TESTING SLIDING GROUNDING CLAMP FOR EARTHING CONDUCTORS TO DOUBLE-CIRCUIT 110 KV TRANSMISSION LINE
KOMUNALNA ENERGETIKA / POWER ENGINERING, 20
This paper presents the testing Sliding clamps for grounding conductor transmission line. For the purpose of an effective transmission line grounding in working with vicinity of high voltage a special form of sliding clamps for grounding has been designed. Grounding device is intended for grounding transmission line conductors, which are dragged along conductor installation on a double-circuit transmission line, the second system operates normally which represents a significant risk for single-phase ground fault . The device must provide such a connection during the sliding along the guide, so that it prevents the arc and effectively discharges ground current into the ground.
Prior to regular usage, it was necessary for grounding the device to perform a series of tests, which are described in this article. A test with the realization of single-phase ground fault was also carried out on the transmission network of 110 kV ELES. All tests have been successful and positive.
