Partial discharge tester UHV-2000A

electricindustriallaboratory

The UHV-2000A is a dual-channel partial discharge (PD) analyzer for detection and analysis of PD in high-voltage equipment such as cables, insulators, bushings and transformers. It provides 2D and 3D visualization of PD activity, supports data and image storage, printing and automatic test report generation.

Product Characteristics

• This console is a dedicated high-voltage non-partial discharge test voltage regulation and operation platform, equipped with start and stop buttons; digital voltage and ammeter indicators, and a time relay for time control and alarming.
• The operating voltage is continuously adjustable, and the waveform is free from distortion and aberration.
• It features a zero position function, as well as protection against overvoltage, undervoltage, overcurrent, and voltage breakdown.
• The alarm is accompanied by sound and light prompts.
• After the test is completed, reduce the pressure back to zero.

Main functions

• Detection and analysis of partial discharges on HV components (cable, insulators, bushings, transformers).
• 2D and 3D display of PD waveforms and maps.
• Data storage, image printing and automatic test report generation.
• Multiple signal input options for integration and export (BNC, optical, USB, network).
