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