Abstract
PURPOSE: To improve the workability, by performing the detection of failed part for long insulator through the relative change between the primary voltage and primary current of the transformer.
CONSTITUTION: The voltage E produced at the secondary of the transformer Tr2 is fed to the wire and cable 1 in running state lengthwise. The voltages Es and Eo appeared across the full wave rectifying stacks Rec1 and Rec2 are measured at the comparator and the relative relation between both the voltages Es and Eo is all informed to the relay. This relay is operated when the relative change between both the voltages Es and Eo is taken place and it is informed to the measuring personnel via the alarm unit.
