Phasing Testers
Phasing Testers

Chance Phasing Testers easily determine phase relationships and approximate voltage, line-to-line or line-to-ground.
Each tester consists of two fiberglass poles with end fittings threaded for interchangeable probes. The probe fittings couple with a high-impedance component encased in each pole. To complete the test circuit, a 22-foot length of insu­lated flexible cable stores on the reel affixed to one pole and connects to the voltmeter on the other pole.
Simple to operate, the tester poles first attach to two 6-foot Epoxiglas® insulating universal handles (included in each kit for proper working clearances). Then the probes can be brought into contact with the conductors appropriate for the meter to read phase-to-phase or phase-to-ground voltage.
For convenience on different systems, toggle on dual-range units can switch calibration between the two scales on the meter face. Plus, it can improve readability for low-end
values on the Hi scale. Switched to the Lo range, those values deflect the needle more to give more finite readings. To check instrument before and after each use, test-point jack in front of meter accepts plug from Phasing Voltmeter Tester.

D.C. Hi-Pot URD Test Adapters
Hi-Pot URD Test Adapters

For quick, reliable fault detection on underground cables, two units are available for phase-to-phase system voltages up to 16 kV or 35 kV. By converting AC source voltage to a rectified half-wave, these adapters permit testing of cables with a potential level equal to peak source voltage. This field-effective method proves especially beneficial for:

  1. Testing new cable before initial energizing.
  2. Testing repaired cable before re-energizing.
  3. Testing suspect cable spans for faults.

For metered readout, the Hi-Pot Adapters work with Chance Phasing Tool H1876. A brass male fitting inside the larger end threads onto the meter probe of the phasing tool. For testing and subsequent discharg­ing, a brass female fitting at the smaller end accepts either Chance Elbow Adapters or BushingAdapters for 15 through 35 kV (page 2455).
Illustrated instruction booklet is included. Units contain high-voltage rectifiers encapsulated in Chance orange IV" and VA" diameter Epoxiglas® housings.
Hi-Pot Adapters measure only 13" in length for 35 kV unit, and 10" for 16 kV unit.

• 600V to 69kV
• For Overhead & Underground

Bright display lights indicate voltage class
This smart new-generation instrument makes hot-line volt­age testing easier than ever. Its state-of-the-art electronics eliminate the need for a selector switch. Its automatic-ranging function quickly displays the approximate line-to-linevoltage class. It provides an easy, yet reliable means for the operator to determine if a line is:

  1. De-energized, or
  2. Carrying less than normal system voltage from any source or induced charged from an adjacent live circuit, or
  3. Energized at full system voltage.

Simple to operate, the tester attaches to an Epoxiglas®insulat­ing universal handle of appropriate length to maintain proper OSHA working clearances. A single pushbutton activates the instrument, then a single light indicates either Power On (by glowing solid) or Low Battery (byblinkirig). With a good battery condition, the instrument performs a confirming self­test by illuminating each ofthe six indicator lights in series while emitting an alternating audible signal.
Then the probe can be brought into contact with the conduc­tor. It automatically begins detecting at approximately 480 Volts and holds the display of one of these voltage classes: 600V,4kV, 15kV, 25kV, 35kV or 69kV phase-to-phase. The audible signal begins as a slow beeping that becomes faster as the final reading is displayed.
When not in use, the unit's energy-saving Sleep mode auto­matically conserves the battery.

Multi-Range Voltage Detector
Multi-Ranging Voltage Detector

Lighted-dial model for systems through 40 kV
Easier-to-read, illuminated dial
The lighted-dial option sets this unit apart from features standard on Multi-Range Voltage Detector (MRVD) C4030979, shown below. Powered by the unit's internal battery (included), a long-life bulb gives a glow to the meter face so the scale is easy to read in most conditions.
To conserve the battery, a special switch locks the light off when not in use. Its spring-loaded toggle must be pulled up to move it over the stop between its on and off positions. This helps keep the switch from being flipped on accidentally while the unit is not in use.
Standard features
To confirm that a line is de-energized prior to performing maintenance on it, the MRVD presents field practicality. Actually a field intensity meter, the MRVD is calibrated to read approximate line-to-line voltage when connected to any phase conductor. It responds to the magnitude of the field gradient between its end probe and floating electrode (at the universal hots tick -attachment fitting). If the universal fitting is close to a ground, another phase or another. voltage source, the reading should tend to be high; if it's close to a jumper or equipment of the same phase, the reading should be low.
The MRVD gives metered readout capable of distinguishing actual line voltage from static or feedover from an adjacent line. Readings from an MRVD can be compared with numeri­cal certainty rather than the subjective judgments associated with "fuzz-sticking" or "glow-detecting." Since the MRVD is not a voltmeter, no specific accuracy is claimed by the manufacturer or can be assumed by the user.
Operation
The MRVD must be mounted on proper length hotstick for the voltage class involved. Complete instructions are furnished with easy, illustrated step-by~step procedures. Internal circuit and pushbutton permit check before and after each use to confirm operational condition of instrument and battery.

URD Voltage Detector

Multi-Range Voltage Detectors for Overhead & URD Systems to 40 kV
This Multi-Range Voltage Detector (MRVD) tests both overhead and underground distribution systems in voltage classes from 5 through 40 k V. This model provides an easy, yet reliable means for the operator to determine if a line is:

  1. De-energized, or
  2. Carrying less than normal system voltage from any source or induced charged from an adjacent live circuit, or
  3. Energized at full system voltage.

For this basic function, this model adapts to both overhead lines as well as URD circuits with 200 and 600 Amp load­break elbows, including those with and without capacitance test-points. Interchangeable probes and adapters just thread into the MRVD end fitting and the selector switch dials to the voltage range or test point (T.P.) setting appropriate to each application. Furnished owner's manual illustrates operating details for all models.

Digital Voltage Indicators
Digital Voltage Indicators

Digital Voltage Indicators for Distribution and Transmission Systems
• Calibrated to read approximate phase-to-phase voltage
Application
As tools for linework, these two Digital Voltage Indicators (DVI) apply to most system voltages. The Distribution DVI provides 1 to 40 kV readouts; and the Transmission DVI covers 16 to 161 kV. For overhead applications, the hooked probe hangs directly onto the conductor or apparatus. For underground systems, the Distribution DVI can indicate voltage at elbow test points or through bushings and elbows.
For such uses as confirming a "dead" condition before plac­ing temporary grounds for de-energized maintenance, both models provide an easy, yet reliable, means to determine if a line is:

  • De-energized ...
  • Carrying less than normal system voltage from any source or induced charges from an adjacent live circuit ...
  • Energized at full system voltage.

Special Design Features
Simply by selecting "Peak Hold," the DVI will retain the display of its approximate highest reading for 10-15 seconds.
A built-in self-test function allows for a quick check of the meter before and after each use.

URD voltage presence test on cable with elbow placed on a feed-thru device can be performed by DVI fitted with Bushing Adapter T4030857. For this test, "Line" must be selected on switch panel of Distribution DVI model. Transmission DVI model does not have Line/Test Point switch.
URD voltage presence test on elbows with test points can be performed only by Distribution DVI model C4032794 fitted with straight Probe and "Test Point" selected on switch panel.

Energized Insulator Testers

  • for Distribution and Transmission Systems

Operation
A sensitive voltmeter, the tester measures the difference in potential across each insulator in a suspect string. Comparative readings from satisfactory strings in the same operating situation quickly indicate the state of every insulator in the string being tested. The meter places only a minimal load on the phase as it requires only a small leakage current to make a reading.
Two straight steel probes threaded into the tester forks simply contact the metal fittings on both ends of each insulator at the same time. Mounted on a 1W'-diameter Epoxiglas® pole with a universal fitting, before each use the tester should be attached to the proper length hot stick for the system voltage involved.
The distribution model's scale reads up to 11 kV. The trans­mission model's scale reads a maximum of 16 kV.
Applications
Without interrupting service, one of these testers quickly can check the condition of each insulator in a string. This greatly reduces maintenance costs. Rather than changing out entire strings, only the insulators identified as damaged require replacements.
Available in two models, the testers serve specific applications: One for deadend insulators on distribution systems through 35 kV, and the other for suspension insulators on 44 kV through 500 kV transmission systems.

Plug-in jack on Insulator Tester meter housing permits line personnel to quickly verify its operable condition with a Phasing Voltmeter Tester (Cat. No. C4030838) before and after each use.

Voltage Tester for Underground Transformers
Voltage Tester for Underground Transformers

The Chance Voltage Tester is a portable device which permits the checking ofthe AC voltages on Underground Distribution circuits through 20 kV for the purpose of determining the approximate line-to-ground voltage of the circuits.
The basic instrument, C4031369, is designed for reading voltages up to 10 kV on the meter. The resistance units are encapsulated in an epoxy compound to protect them from mechanical damage and to prevent moisture penetration or accumulation around the resistors. No calibration is required, the tool is preset at the factory.
For use on voltages above 10 kV phase-to-ground, an extension resistor, is provided, increasing the voltage range to 20 kV phase-to-ground. (Do not use more than one extension resistor element per tool.)
The ground connection is made to a stud on the stick below the meter housing. This stud MUST be electrically connected to a good ground source.
Before the Voltage Tester is used to test elbows or bushings on dead front URD equipment, the proper adapter must be attached to the tool.
Elbow must be controlled or restrained with an insulated hot stick while using Voltage Tester to check elbows. Elbow must be properly parked when bushing is being checked.

Energized Cable Sensor
Energized Cable Sensor

The purpose of the Energized Cable Sensor is to allow the lineman to readily determine whether a URD cable is energized or de-energized. The sensor consists of an amplifier which is designed to give a meter reading when the small AC voltage between the semi-conductive sheath and the concentric neutral of the energized URD cable is applied to the test probe. The amplifier is housed in a rugged thermoplastic case. Sensor may be used to check for energized condition on concentric-neutral cable below an elbow without test points (as above). At cable mid-span (left), hose clamps bridge all strands of concentric neutral at the test location. Sensor's neutral lead clips to one of the hose clamps. Tip on probe lead contacts only semi-conductive cable sheath to test for voltage presence.

Line Fault Locator
Line Fault Locator

The device is for use on underground distribution lines, 115 volts through 34.5 kV, with fault location potential up to one megohm.
The Chance Line/Fault Locator consists of four units.
The Line Locator is made of Epoxiglas and is self-standing for free use of both hands. It is used as a "wand", sending a null-out to the audible sound through the unit as an indica­tion of proximity to induced current in a buried cable.
The Fault Locator, also made of Epoxiglas, is designed to receive a signal from the transmitter through the two earth probes, interrupting the signal when the two probes are equidistant from the fault: 90° locations are then established from the handle of the tool to pinpoint the fault.
The Transmitter emits a 90-volt square wave, 115-cycle signal and is complete with one 12-volt battery installed in the carrying case.
The Receiver amplifies the signal of the Transmitter and/or the 60-cycle field around a conductor carrying current; includes six "AA" Biz-volt batteries, volume control and neck strap. Earphones are available for plugging into the receiver, eliminating background noises.

Protective-Grounding Set Tester
Grounding Set Tester 1
Grounding Set Tester 2
  • U.S. Patent 5,811,979
  • Meets ASTM Standard F 2249
  • Microprocessor technology for easy, accurate diagnostics

Self-contained, portable convenience
This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel. Powered by 120 VAC, the tester applies Direct Current across the test specimen. A seven-minute videotape, included with each unit, shows how simple the tester is to use. Procedure details are given in the instruction manual. All components store in the tester's integral carrying case.
Simple, one-button testing
From pushing a single button, the digital display shows the resistance measured in milliohms compared with a preset threshold for the size grounding cable selected (#2, 1/0,2/0 or 4/0). A green "Pass" or red "Fail" light also indicates the test result's relation to the threshold.
For system-specific requirements, the user can easily change the Tester's basis for voltage allowed across a lineworker, which comes factory preset at 100 Volts. Adjusting this limit automatically causes a corresponding shift in the resistance thresholds for all the grounding cable sizes.
Regardless of the voltage-allowed setting or cable size selected, the Tester displays the resistance of each specimen in milliohms with ±1 % accuracy, from 1 micro-ohm to 6.5 ohms. The utility must establish the maximum resistance allowed for protective grounding sets used on each specific area of its systems. How the utility calculates these values depends on several factors outlined in the Tester instructions. Sample calculations with reference tables and charts are given in the manual.
Troubleshooting mode
If a ground set does not pass the initial test, the Tester can help isolate the problems. Often, the source of high resistance can be remedied by simple repairs to the cable set. Retesting then can quickly verify the effects of repairs.
For this troubleshooting mode, a pair of test probes are furnished to plug into the Tester. A switch activates them instead of the ball-stud terminals. The probes then are used to test across each contact interface in the ground set. The results display in milliohms, just as in the first test mode.
Optional terminals for special ground sets The Tester's standard ball-stud terminals accept most types of ground clamps, including Chance ball-socket clamps.
To test special-application grounding sets for underground­distribution transformers or switchgear, two optional adapters shown above are available as separate items.

LoadLooker Ammeter

  • Models for Distribution, Transmission and Substation uses
  • Hold feature for easy hotstick use
  • U.S. Patent 5,057,769

User-friendly electronic-loop design
Instead of you manipulating a hinged or clamp-type inductive pick-up, the patented LoadLooker electronically closes the loop for you. Its unique U-shape jaw senses the amperage present between its tines. The open-end design lets you check loads on components not accessible by other hot-line ammeters.
Live-line-ready hotstick mount
A standard fitting on the LoadLooker lets it mount on your insulated hotsticks just as any other universal tool. Your hot-line crews can begin using it immediately, in compliance with prescribed safe-working clearances for your system voltages.
Simple pushbutton operation, direct-reading accuracy
A single button controls the operation. Push it once to turn on the LoadLooker. Push it a second time and LoadLooker will display the word HOLD and continue to display the next reading it "sees" until you push the button to clear it. This lets you bring it down from the line to eye level to read it. After five idle minutes, the unit will itself turn off or you can manually turn it off by keeping the button depressed for five seconds. A detailed Operators Manual and storage case are included with each LoadLooker.
Rugged, application-specific design Materials selected for the LoadLooker and how it is constructed are designed for the rigors offield conditions. Typical applications include identifying load imbalances, verifying the accuracy of current transformers, determining load to select properly sized jumpers, and measuring load before opening switches.

Wet/Dry Hot Stick Tester
Wet/Dry Hot Stick Tester

• U.S. Patent No. 5,684,405

Wet/Dry Hot Stick Tester for easy, portable compliance with industry standards Controls and meter for all requirements
Simple to operate, this portable unit makes easy work of testing insulated live-line tools. It features wet and dry modes selected by a toggle switch and follows procedures specified
by ASTM, IEEE and OSHA. Its graduated meter gives precise readout of each tool's leakage current.
Portable operating ease
For testing any length fiberglass-reinforced plastic (FRP) hot stick up to 3 inches in diameter, the WetJDry Tester offers convenience for spot checks at fieldjobsites or periodic diagnostics in the workshop. It's like having full-scale test setups for both Wet 75kV-per­foot and Dry 100kV-per-foot in a compact, self-contained unit easily carried and operated by just one person. In the Setup procedure before each use, a zeroing knob is used to set the meter to zero without a tool in the tester. Then the furnished Check Bar is used as a self-check to make sure the tester is functional. A seven-minute videotape included with each unit demonstrates "how-to" basics for Setup, Dry and Wet tests. The illustrated Owners Manual gives specifics which must be read and understood before operating the tester.
Quantitative test results
When the tester is placed on a tool, the meter displays any increase in leakage current due to the hot stick's presence. This gives an immediate indication of the stick's true leakage condition, independent of stray currents (through the air, internal to testers, etc.) zeroed out in advance.
The tester detects leakage currents due to surface contamination, internal moisture and such internal conductive materials as carbon tracks.
