1.The multi-frequency induced withstand voltage test device is
mainly used for induced withstand voltage tests on transformers and
instrument transformers. It can perform induced withstand voltage
tests on the longitudinal insulation between turns, layers,
sections, and phases of instrument transformers and transformer
windings.
2.This device employs power electronics technology, with a
frequency converter as its core component. It includes parameter
presets, protection settings, frequency selection, and voltage
regulation control.
3.It utilizes digital control technology with a built-in computer.
4.The output power is relatively high, up to 200Hz. Compared to
traditional third-harmonic frequency generators, it has higher
operating efficiency, more stable output voltage, higher
measurement accuracy, and better repeatability.
5.Ten layers of protection ensure personnel and equipment safety:
The instrument provides multiple protections including user
emergency stop, user shutdown, hardware protection, source output
overcurrent protection, temperature protection, overvoltage
protection, and protection against sudden increases and decreases
in high voltage and current, thus maximizing the safety of
personnel and equipment.
6.Output can be disconnected within one output cycle:
If an anomaly is detected during the test, the instrument can
disconnect the output within one output cycle.
7.Real-time high voltage recording and printing for convenient test
analysis:
The instrument records the external high voltage value every second
during the test and saves it in the background. After the test, the
real-time high voltage data for each second can be printed out for
convenient user analysis.
