Product Description

Series Resonance Test Equipment Factory Direct

Darui Electric recommends:

The series resonance principle is a product. The variable frequency series resonance test device uses the series resonance principle, using an excitation transformer to excite the series resonance circuit, adjusting the output frequency of the variable frequency controller so that the loop inductance L and the test product C resonate in series, and the resonance voltage is the voltage applied to the test product. The variable frequency resonance test device is widely used in electric power, metallurgy, petroleum, chemical and other industries, suitable for handover and preventive tests of large-capacity, high-voltage capacitive test products.

Test Objects

1. AC withstand voltage test for 6kV-500kV high-voltage cross-linked cables

2. AC withstand voltage test for generators

3. AC withstand voltage test for GIS and SF6 switches

4. Power frequency withstand voltage test for 6kV-500kV transformers

5. AC withstand voltage test for other high-voltage power equipment such as busbars, bushings, and instrument transformers.

Selection Basis

The variable frequency series resonance test equipment is different from general-purpose testing instruments. The biggest feature is that the same set of equipment can be used for AC withstand voltage tests of different electrical equipment such as cross-linked cables, transformers, GIS, motors, and generators. In addition to the series of typical commonly used models provided in this selection catalog for users to choose, it is usually necessary to design configuration schemes based on the user's test object range and test requirements to meet the test requirements of different regions, different users, and different test objects.
