Megger manufactures voltage detectors and phasing testers, detex . The product is used on any grounded electrical system. Voltage detectors are available in seven models that cover a range from distribution class to transmission line voltages up to 550 kv. There are six electronic beeper models and one model with led indication for greater visibility when used for testing indoors. The beeper-style electronic detectors provide audible and visual indication of the presence of phase-to-ground ac voltages. All models are fitted for universal spline mounting on a hot line pole rated for the voltage of the system being tested. The led-indicating voltage detector is designed for indoor testing of grounded ac systems. The salient features of the voltage detectors and phasing testers:
