best gas insulated substation leak pointer

Sep 21, 2016A defective gauge pointer along with a small oil leak can result in catastrophic failure of a bushing, causing damage to the apparatus and other switchyard equipment nearby. Low oil levels in the busing should be corrected by checking the mounting bolts for adequate torque and inspecting the gasket for proper compression.
