摘要/描述

A principle for resonance measurement based on injectingresonant frequency signal is presented in this letter. The groundingcapacitance of lines and equipment and the grounding fault resistancecan be measured on-line in ineffectively grounded systems.Petersen-coil automatic tuning is implemented, and 100% statorgrounding fault protection for generator stator windings is also proposed.The prototype for Petersen-coil tuning has been tested on networksfor many years. In addition the new method for generator statorgrounding fault protection is verified by simulation.
