  • Measurement Of Resistance Or Impedance (AREA)

Abstract

PURPOSE: To measure insulation resistance easily and safely by the method wherein the effect of the induced AC component of the line to be measured is removed by a resistor and a condenser, and by impressing high DC voltage on both terminals of the condenser, the DC voltage of the line to be measured is measured.
CONSTITUTION: Resistor 5, which combines the function of a voltage resisting protective resistor capable of withstanding high voltage and a standard resistor for measuring insulation resistance, is connected in series with condenser 6. The ratio of the impedance with respect to the commercial AC frequency of resistor 5 to that of condenser 6 is taken sufficiently large. A series circuit of high DC voltage generator 9 and indicator 10 is connected to both terminals of condenser 6. Consequently, inducted AC voltage on both terminals of condenser 6 becomes very small, and condenser 6 becomes a large impedance compared with line insulation resistance 3 with respect to DC, so that it is possible to measure insulation resistance safely by measuring DC resistance accurately even when line 2 to measured is subjected to larger induction as compared with neighboring line 1.
