Recently, Kunshan Vekan Electronic Technology Co., Ltd. has completed on-site installation and commissioning of the DEMIKS DJF-3KVA 3kV compact partial discharge test chamber. This partial discharge testing system is now in operation within their quality control lab, dedicated to partial discharge testing and power frequency withstand voltage tests on new energy high-voltage busbars, copper bars, shielding parts and electrical connectors, providing professional high voltage power testing for insulation reliability verification before product shipment.
As a manufacturer specializing in precision high voltage electrical components for electric vehicles and energy storage systems, Kunshan Vekan Electronic supplies critical parts for energy storage PACKs and electric control units. High voltage busbars serve as key current-carrying components; voids, delamination and interface defects inside insulation materials may trigger partial discharge under high voltage stress. Continuous partial discharge will degrade insulation gradually and eventually lead to breakdown and safety failures. With increasingly strict global HV safety standards for new energy components, partial discharge testing has become an indispensable factory QC procedure.
The delivered DJF-3KVA 3kV compact partial discharge test chamber is an all-in-one integrated PD test system. It integrates a partial discharge-free voltage booster, high-sensitivity PD acquisition module and built-in shielding cavity. It combines PD test room and hipot test chamber in a single unit, removing the requirement to build a standalone large partial discharge shielding room, which makes it ideal for factory QC laboratories. The touchscreen industrial PC can display HV values and PD patterns in real time, record test data automatically. It supports batch sample testing, measuring pico-coulomb partial discharge signals and evaluating insulation defect severity, complying with type test and factory sampling high voltage power testing requirements.
Equipped with this partial discharge test equipment, Kunshan Vekan Electronic achieves full validation of insulation performance for HV components. Hidden insulation defects can be identified at the production stage to mitigate high-voltage risks for downstream energy storage and EV control systems, meeting international customer test specifications.
DEMIKS specializes in high voltage power test equipment, including compact PD test systems, large partial discharge shielding rooms, variable frequency series resonance sets and lightning impulse generators. This cooperation with Kunshan Vekan Electronic demonstrates the reliability of DEMIKS DJF series partial discharge test equipment for new energy busbar and connector QC testing, offering cost-effective, compact partial discharge measurement solutions for manufacturers of electrical power components.
FAQ People Also Ask:
- Why perform partial discharge testing on new energy high voltage busbars?
Voids or delamination inside busbar insulation will cause partial discharge under high voltage. Persistent PD activity erodes insulation and may cause catastrophic short circuits. Partial discharge test equipment detects invisible insulation defects during factory inspection to ensure safe long-term operation of energy storage and EV systems.
- What are the advantages of the DJF-3KVA compact partial discharge test chamber?
The DJF-3KVA 3kV PD test chamber integrates a shielding cavity and HV booster in one cabinet. It occupies limited floor space and no extra PD shielding room is needed. The built-in PC captures PD patterns and generates test reports automatically. Good anti-interference performance enables partial discharge testing inside factory workshops for samples up to 3kV such as HV busbars and connectors.
- What high voltage power testing can partial discharge test equipment carry out?
The system performs partial discharge testing together with AC withstand voltage tests. It quantifies PD magnitude, generates real-time PRPD patterns and archives test reports for factory sampling inspection, type tests and incoming insulation verification of new energy HV components.
