Product Description
HGFS Non-localized Discharge Multi-frequency Inductive Voltage Withstand Test Instrument
II. Performance and Applications
For electromagnetic voltage transformers (PT) rated at 220 kV and below, conduct induction withstand voltage tests and partial discharge tests (some equipment requires inductive compensation).
III. Functional Features
- The trial demonstrates good equivalence. The output of this device is a sine wave with minimal waveform distortion, exhibiting a waveform distortion rate of <3%.
- Small in size, lightweight, and easy to handle, making it highly suitable for on-site use.
- The operation is simple and convenient, with straightforward wiring.
- Safe and reliable, this device integrates multiple protection features, including discharge breakdown protection, overvoltage setting protection, output short-circuit protection, and startup zero-level protection.
- The system employs microcomputer control, ensuring excellent output stability. The signal source in this device is generated by a dedicated chip, delivering high-frequency output stability up to 0.001 Hz. Additionally, the output voltage is precisely controlled by the microcomputer, guaranteeing an instability rate of <1%.
