PT Potential Transformer Replacement Operation Standard Procedure and Temporary Power Supply Device Load Break Switches for Underground Line

摘要

The ground switch PT replacement standardization method using the temporary power transmission device (1) of the present invention is based on the standard operation manual when the PT (Potential Transformer) 140 of the ground switch 100 is defective or damaged (S20) ,S30~S50/S30-1,S30-2,S100), temporary power transmission establishment (S60-1), defective PT on-site replacement (S70), and defective PT on-site inspection (S80) In the temporary transmission establishment state using (1), the on-site replacement of defective PT (S70) is constructed on-site according to the work procedure of the standard work manual, so it is possible to improve the safety/efficiency of the PT replacement and minimize the blackout time, especially the PT replacement standardization method Through the establishment of standard operation manual of
