Profile:
For onsite cable testing, the variable frequency resonant test system is a mobile and easy to use solution based on the latest technology in frequency converters for testing up to 500 kV cable class. The HMCXZW series of on-site cable test systems are based on the latest frequency converters to facilitate testing of long lengths of cable in the field with fixed core, variable frequency reactors. These reactors are lighter and more powerful compared to variable inductance fixed frequency reactors. The system’s low noise level is optimized to allow partial discharge measurements with the PD, including PD site location along the length of the power cable.
