Motor Coil/Partial Discharge/Insulation Evaluation System
[Contact Us]
The PD ONE Motor Coil Partial Discharge and Insulation Evaluation System by ECG KOKUSAI is designed for comprehensive insulation testing of industrial motors and EV/HEV motor coils.
It supports AC and impulse partial discharge testing, AC withstand voltage testing, and flexible test circuit configuration via a 6-channel switching system.
Using a microwave patch antenna for detection, PD ONE accurately measures PDIV and PDEV, enabling reliable insulation quality evaluation and defect detection.
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
Image
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.
