Overview
The variable frequency resonant test device is widely used in electric power, metallurgy, petroleum, chemical and other industries. It is suitable for capacitive test objects with large capacity and high voltage, such as generators, transformers, GIS, high-voltage cross-linked cables, transformers, bushings, etc., for commissioning tests and preventive tests.
Device Composition
The variable frequency resonant test device consists of a variable frequency power supply, an excitation transformer, a reactor, a voltage divider, and a compensation capacitor.
