Abstract
PURPOSE: To secure the measurement of dielectric loss tangent by a method wherein a one-end-grounded test sample is connected between the main body of a bridge device and a power source and a super-low-frequency power source is employed as the power source.
CONSTITUTION: A bridge device 1 is constituted, as shown by a dotted line, by a variable resistance R3, a parallel circuit of a variable capacitor C4 and a fixed resistance R4 connected in paralled to the resistance R3, and a detector D connected between the above parallel circuit and the variable resisntace R3, and is built monolithically in an apparatus. In addition, a power source Ea and a standard capacitor Cs are also connected. And, by using a super-low-frequency power source as the power source, the floating electrostatic capacity Co between the power source and the earth is controlled to be small and thereby the error in measurement of the electric loss tangent is reduced. In addition, by grounding a test sample at one end thereof and reducing the difference in potential between a point A of the bridge device and a point 0 where the test sample is grounded, the bridge device is prevented from being of high voltage and thus the measurement can be secured.
