Title: Simple method for measuring insulation resistance of low-voltage wiring and the like
Inventor: MATSUNO TATSUJI
IPC: G01R27/18
Filed: 1988-12-08
Abstract: PURPOSE:To enable outdoor measurement of insulation resistance by impressing a signal frequency for measurement on a wiring while detecting a voltage existing between a necessary part of the wiring and the ground and by minimizing the component of the signal frequency for measurement contained in an output of a current transformer. CONSTITUTION:An injection transformer OT is coupled to an electric wire inside or outside a home whereon a load apparatus H0 is set, while an oscillator OSC is connected to the transformer OT, and a signal frequency for measurement is injected into electric circuits L1 and L2. Moreover, a zero-phase current transformer ZCT is made to pierce through the electric circuits L1 and L2, an output thereof is inputted to a filter FIL for extracting a frequency component, and an output of the filter FIL is rectified by a rectifier DT and then indicated by a meter M. Besides, a voltage between the electric circuit near a node of the transformer OT and the ground is detected by a high input impedance amplifier A1 and an output thereof is impressed on a conductor through which the current transformer ZCT is pierced, while the conductor terminates at a variable resistor RV. In this constitution, the value of the resistor RV connected to the conductor is varied so that the value of the meter M be minimum, and insulation resistance R is measured from the resistance value of the resistor RV which turns to be minimum.
