Title: Insulation resistance measuring method
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1981-10-01
Abstract: PURPOSE:To measure easily an insulation resistance in the live-wire state, by integrating a leakage current in two kinds of intergrating tiem which are integral multiples of the fundamental period of commercial frequency and obtaining average values in respective integrating times and operating them in four rules of arithmetics. CONSTITUTION:The leakage current fed back to an earth line EL is detected by, for example, a current detecting probe CD and is amplified by an amplifier AMP. As the output of the amplifier AMP, the result of the addition between a measure signal current waveform and leakage current components of commercial frequency components is obtained. The output of the amplifier AMP is led to two integrators INTEG1 and INTEG2, and integrating times are set to integral multiples of the period of commercial frequency components. Averages in respective integrating times are obtained and are operated in four rules of arithmetics to calculate and measure the insulation resistance. Thus, since the influence of commercial frequency components upon average values is eliminated, the insulation resistance in the livewire state is measured very easily.
