Title: Corona detecting method
Inventor: TANI MASAAKI
IPC: G01R31/12
Filed: 1992-04-08
Abstract: PURPOSE:To detect corona where a frequency is close to a higher harmonic component by relatively regular superposition onto a fundamental wave including the higher harmonic component. CONSTITUTION:Only a higher harmonic component which is superposed on a fundamental wave is extracted by a high-pass filter 1 and the waveform is shaped into a pulse by a comparator 2. The number of pulses is counted by a counter part 6. The number of counts corresponding to the high harmonic component which is obtained previously from the superposition state to the fundamental wave of the higher harmonic component is subtracted from the count value of the counter part 6 using a higher harmonic component elimination means A. The subtraction result is converted to an analog data by a D/A conversion part 7. By integrating the analog conversion data using a low-pass filter 13, a time-averaged value is obtained. The average value is compared with the reference value by a comparator 14 and presence of corona is determined when the reference value is exceeded.

Abstract: PURPOSE:To make a dot display where an original physical phenomenon waveform is reflected by displaying the maximum and minimum value of the physical phenomenon waveform which are extracted by a maximum and minimum value extracting means and displayed with bits to be thinned out along with a physical phenomenon waveform value which is indicated with display bits. CONSTITUTION:A CPU 1 fetches the physical phenomenon waveform value from a sensor 3 in time series through an interface 4 and stores it in a main memory 2 temporarily. Then when the CPU 1 reduces and displays the physical phenomenon waveform value stored in the memory 2 on the screen of a CRT 7, the CPU 2 reads the physical phenomenon waveform value out of the memory 2 while thinning out specific bits, and then write it in a buffer 5 and also finds the maximum value and minimum value of the physical phenomenon waveform value indicated with the thinned-out bits, thereby writing it in the buffer 5 along with the physical waveform value of display bits. A CRT controller 6 displays the physical phenomenon waveform value written in the buffer 5 at the same horizontal position on the CRT 7. In this case, if there is a gap encircled with dots at the same position on the CRT 7, the controller 6 performs control so as to make a display while filling the part with dots.
