• Grounded or ungrounded ac system check
• Five models


For use on any grounded electrical system, DETEX Voltage Detectors are available in seven models that cover a range from distribution class to transmission line voltages up to 550 kV. Biddle offers six electronic "beeper" models and one model with LED indication for greater visibility when testing indoors.

The beeper-style electronic detectors provide audible and visual indication of the presence of phase-to-ground ac voltages, in accordance with ANSI C84.1-1982 standards.

The 6.9-kV model is equipped with a telescopic pole. All other models are fitted for universal spline mounting on a hot line pole rated for the voltage of the system being tested.

Electronic voltage detectors for use on distribution line voltages (Cat. No. 514360 series) provide a single red LED.

Detectors rated for transmission line voltages (Cat. No. 514242 series) provide four LEDs for improved visibility at greater distances.

The LED-indicating voltage detector is designed for indoor testing of grounded ac systems. A bright LED indicator provides easy visibility in poor lighting conditions. During testing, the presence of voltages within the detector's operating range will illuminate the bright LED lamp.

A built-in piezoelectric voltage source provides a test feature to ensure that the detector is operative before use. The self-test is activated by a pushbutton.

The LED detector is equipped with a 48-in. (1219-mm) telescopic pole calibrated and marked for voltages within the ratings of the detector. These demarcations assist the user in adjusting the pole to the length required for safe operation. The pole retracts to 34 in. (864 mm) for convenient storage in a vinyl carrying case when not in use.


High-Pot Testers

AC/DC High-Pot Tester

Circuit Image
Rapid production-line testing to latest UL standards
• Extra safety features
• Rugged design for portability

The AC and AC/DC High-Pot Testers are designed for safety and ease of operation, and readily adapt to development, maintenance and production testing. Three models are available: two ac and one ac/dc. These instruments test the dielectric strength of electrical insulation and the ground circuit continuity of three-wire appliances and other devices. They feature front-panel adjustable leakage current trip, one-second or continuous testing, and automatic failure shutdown.



Circuit Breaker Stab Sets

Circuit Image
Connect to virtually all Multi-Amp circuit breaker test sets
• Provide quick connection to breaker under test
• Can accommodate over 70 types of breakers

Model CBS-1 and Model CBS-2 Circuit Breaker Stab Sets allow connection to virtually all Megger circuit breaker test sets. Their use eliminates the significant losses that occur if leads are used to connect the breaker under test to a test set.

These stab sets allow testing of drawout style metal-clad breakers. (Cables must be used when testing molded-case circuit breakers or other devices that will not connect directly to the stab.)



Circuit Breaker Analyzer (One Break Per Phase)

Circuit Image
Suitable for testing timing and travel on all circuit breakers with single interrupter per phase
• Extremely easy-to-use and reliable
• Two separate timing channels for measurement of auxiliary contacts
• Analog measurement channels for travel transducers or general voltage/current measurements
• Static and dynamic resistance measurements along with the SDRM201 accessory

The Programma EGIL is an automatic timer and motion analyzer for medium- and high-voltage substation circuit breakers. It is intended for use on circuit breakers with one contact per phase. EGIL incorporates features commonly found on more complex test systems, but is designed to be smaller, simpler to use and less expensive than other similar test sets. It’s price makes it attractive to smaller utilities and it is an ideal supplementary product for maintenance departments at larger power companies and for testing contractors.
