Mobile HV AC Test System
The system stays within the load and size limitations for permission-free road use. Additionally, the matching transformer and the reactor are filled with ester instead mineral oil. Thus, it can be easily transported to a substation, power plant, or other high voltage areas for testing HV components after installation or repair. Additionally, it is applicable for condition assessment and fault investigations. PD measurements can be performed in non-shielded environments as part of the on-site acceptance test on a power transformer, or as a method to locate PD failures acoustically, or by electrical measurement.
