Tunable Frequency Resonant Test System

Voltage: up to 2400kV

Frequency: 20-300Hz

Variable frequency resonant test system varies the output frequency to tune the system to the load capacitance creating a resonant circuit. And the output frequency is typically in the range of 20 to 300Hz. It is ideal for commissioning tests of power cable and GIS/GIL.

Compared to conventional AC test transformer, the relatively low testing power required, and the ability to make a direct comparison of the factory and field tests, favors the variable frequency resonant test system as the most practical on-site test system.
