DETERIORATION DETECTOR FOR ARESTER INSULATOR

摘要

PURPOSE: To carry out the measuring work for the electric characteristic of an arrester insulator easily and safely by connecting a contactor at the top edge of a detection part in simple manner with the arc ring of the arrester insulator. ;CONSTITUTION: A high voltage protecting circuit 33 is connected with contactors 29 and 30. On the input side of the high voltage protecting circuit 33, a condenser Cx having the electrostatic capacity larger by 2-3 digits than the electrostatic capacity Cs of an arrester insulator 7 and the electrostatic capacity Cg of the aerial discharge gap G is connected in parallel to the arrests insulator 7.;COPYRIGHT: (C)1993,JPO&Japio
