Abstract

PURPOSE:To simplify the configuration of a capacitor voltage dropping circuit by connecting a series circuit of a main capacitor and a voltage dividing capacitor between a high voltage wire and an earth and connecting an electric device in parallel with the voltage dividing capacitor. CONSTITUTION:A voltage 31 to be dropped is divided by a ratio of the impedances of a main capacitor 32 and a voltage dividing capacitor 33, and a dropped voltage is presented across the capacitor 33. The capacitor 33 has the capacity of the degree capable of ignoring the affect of the capacity at this time so that the variation in the capacity of an electric device caused by replacing the electric device 35 may not affect the ratio of the dividing voltage.
