IMPROVEMENTS INTRODUCED IN MONITORING SYSTEM OF DIELECTRIC STATE OF HIGH VOLTAGE EQUIPMENTS WITH CAPACITIVE INSULATION, SUCH AS CONDENSIVE BUSHINGS, CURRENT TRANSFORMERS, POTENTIAL TRANSFORMERS AND SIMILAR
摘要:
A system and method for monitoring a dielectric state of high voltage equipment. A leakage current is measured and compared to a programmed limit value. An alarm is activated if the leakage exceeds the limit value to indicate that insulation has seriously deteriorated. The leakage current measurement is verified using a comparison of individual leakage currents with a change in a vector sum of leakage currents.
