VLF Hipot Tester-Catalog

Product catalog summary

Product Introduction
The VLF Hipot Test Set by Wuhan UHV Power Technology Co., Ltd. is designed for high-voltage withstand voltage testing of electrical equipment, crucial for insulation preventive tests. It supports both AC and DC tests, with a focus on the 0.1Hz ultra-low frequency technology recommended by the International Electrotechnical Commission. This method is favored for its efficiency and reduced equipment size and weight compared to traditional power frequency tests.

Advantages of 0.1Hz Ultra-Low Frequency Testing
The 0.1Hz ultra-low frequency test is an alternative to power frequency tests, offering equivalence in results while significantly reducing equipment size and weight. It is particularly beneficial for large-capacity test samples like generators and power cables, where traditional methods require bulky and expensive transformers.
