A MODULE TEST-SET UP AND METHOD FOR HIGH VOLTAGE GIS BAY DI-ELECTRIC EVALUATION

摘要

A module test-setup to facilitate testing procedure of gas insulated circuit breaker (CB), disconnector switch (DS), earth switches (ES), gas to air bushing, current transformer (CT), voltage transformer (VT), surge arrestor (SA), bus bars and bus ducts designed to form different substation configurations. Gas insulated substation bay comprising these modules are subjected to undergo a variety of tests during manufacturing stage, requiring high voltage connection between the high voltage generator and the module to be tested. The proposed method of evaluation is also suitable for compact gas insulated bus duct / lines wherein all the three phases are in a single enclosure.
