MEGGER 514242-2 VOLTAGE DETECTOR - For use on any grounded electrical system, These Voltage Detectors are available in seven models that cover a range from distribution class to transmission line voltages up to 550 kV. Megger -Biddle offers six electronic ?beeper? models and one model with neon 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.
