| Abstract;Here were introduced an energy diagnosis apparatus (EDA) mounted at a receiving cubicle and a distribution board in customers to measure electric power at every loads such as air conditioning, illustration, and so on, and an insulation monitoring apparatus (IMA) to normally monitor low voltage electric systems in an electric installation to detect electric leakage (grounding accident) based on its insulation faults. For EDA, its cost down was planned by adopting a wide range of CT as a sensor for current measurement, and for IMA, by adopting a method obtaining components based on grounding accidents from grounded currents by vector operation, its cost down and workability upgrading were realized. |
