Discharge testing machine

Motor Coil/Partial Discharge/Insulation Evaluation System

PD ONE

Features

  • Undertaken partial discharge tests, AC withstand voltage tests, and impulse tests is necessary for insulation testing of industrial motors, EV / HEV motors, etc.
  • A voltage application circuit can be selected arbitrarily with a 6CH switching circuit.
  • The partial discharge test supports both AC and impulse, and can measure PDIV and PDEV respectively. Detection is a microwave patch antenna.

Overview

Test circuit

Test circuit can be arbitrary set between phases, turns, grounds, etc.

AC test and impulse test can be performed 6 times each. The Hi / Low settings of terminals 1 to 6 and the GND terminal can be combined freely and can be checked on the screen.


Test screen

Test conditions are created on a PC and stored in the PC. Test results (judgment / numerical data) and waveform images can also be saved on a PC.
