Overview
The variable frequency resonant test device is widely used in electric power, metallurgy, petroleum, chemical and other industries. It is suitable for large-capacity, high-voltage capacitive test objects, such as generators, transformers, GIS, high-voltage cross-linked cables, mutual inductors, 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.
