PDIV Tester for EV Motor
PDIV 500-T
Shanghai Dean Electrical Co., Ltd
Differing from partial discharge with high frequency pulse which produce sound and light phenomenon, the power frequency AC voltage reaches a certain threshold, can only produce instantaneous current leakage around the tested sample, it can be detected through discharge capacity (unit: PC) to evaluate partial discharge phenomena..The instrument PDIV 500-T is designed to put samples such as enameled wire, insulation paper/film, and electric motor stator in the High temperature / humidity environment chamber, applying a power frequency voltage with a programed rising speed, and prefect ground connection must be guaranteed , through the coupling capacitor as the medium, the continuous detection of discharge capacity against the voltages will create formulation between the Voltages and discharge capacities (pc), the software will find the discharge voltage threshold called PDIV.
