TPT420

Voltage Detector

  • CAT IV/1000 V
  • IP64 Rated
  • 12 - 1000 V AC
  • 12 - 1500 V DC
  • Continuity test function with a visual and acoustic indication
  • Voltage indication with no batteries
  • Single pole voltage test
  • Phase rotation indication
  • Integrated torchlight

The Megger TPT420 voltage tester is designed to provide electricians and electrical engineers with an easy-to-use voltage indicating instrument. The meter will continue to warn the operator of dangerous test voltages even when the batteries are exhausted. With both LCD and LED displays, the TPT420 provides both AC and DC voltage measurement - from 12 to 1000 V AC and up to 1500 V DC. In addition, a continuity function within the range 0 to 500 kΩ, is included and for added safety, continuity and voltage measurements are also accompanied by an acoustic sounder.

DETEX

Voltage detectors and phasing testers

  • Voltage detector
    • Seven models available
    • Continuous monitoring
    • IEC conformance
  • Phasing tester
    • Two models available
    • Grounded or ungrounded AC system check

For use on any grounded electrical system, the DETEX voltage detectors and phasing testers are also piezo verifiers. Piezo verifiers are an essential safety tool used to confirm the correct operation of voltage detectors and phasing testers that do not have a self-testing capability. When the verifier handle is depressed at the rate of 3 strokes per second, a piezo crystal generates approximately 1800 volts. This voltage, when applied to the tip of the detector, tests the integrity of the current path and ensures the proper operation of the indicators.

All DETEX models provide continuous monitoring with no on/off switch.

Voltage detectors

The voltage detectors come in seven models that cover everything from distribution class to transmission line voltages up to 550 kV. These models include six electronic 'beeper' models that provide audible and visual indication of the presence of phase-to-ground AC voltages, in accordance with ANSI C84.1-1982 standards. They also include one model that uses an LED indicator designed for indoor testing grounded AC systems as the bright LED provides easy visibility in poor lighting conditions.

Phasing testers

The phasing testers come in two models for applications up to 34.5 kV systems. These models have LED indication
