Product Description
680kVA 270kV Variable Frequency AC Resonant Test System
The 680kVA 270kV Variable Frequency AC Resonant Test System is intended to support specified AC withstand voltage testing applications for compatible capacitive electrical equipment. The rated capacity and rated voltage are important initial references when evaluating the system for a transformer testing project. The final selection must take into account the transformer's electrical characteristics, required test voltage, capacitance, test duration, operating conditions, site environment, and applicable technical specification.
Large power transformers and high-voltage bushings are relevant application objects to consider, including testing projects associated with 110kV and 220kV main transformers. Each transformer project has its own requirements, and the system must be checked against the specified test conditions before its suitability is confirmed. Sansion Power can review the information supplied by the customer and discuss the appropriate equipment scope, including the proposed resonant reactor arrangement, power supply, excitation transformer, voltage measurement, control functions, and agreed accessories. The final configuration should be stated in the project-specific technical documentation.
