Title: Electric leak detection device
Inventor: OSAWA KEN
IPC: G01R31/02
Filed: 2001-07-10
Abstract: PROBLEM TO BE SOLVED: To detect accurately existence of an electric leak between a high- voltage circuit and a low-voltage circuit. SOLUTION: Even if a short-time noise is superimposed on a sine-wave output from the high-voltage circuit 10 through a coupling capacitor 32, a soft filter means 351 removes only voltage data for leak detection corresponding to a minute time part in which a noise component is detected from the voltage data for leak detection, and a leak detection means 352 compares the maximum voltage value Vmax in the remaining voltage data for leak detection after soft filter processing with a threshold VT for leak detection, to thereby detect the existence of the leak between the high-voltage circuit 10 and the low-voltage circuit 20. Therefore, false detection of the leak caused by the noise can be prevented.  Otherwise, the existence of the leak can be detected by integrating the voltage data for leak detection with a prescribed period T to operate an effective value of a sine-wave rectification output, and comparing the effective value with a reference effective value.
