The resistance-capacitance absorber is used in conjunction with the shunt reactor and is an important power grid equipment used to absorb the intercepted over-voltage generated during the switching process of the vacuum circuit breaker. However, the quality of the RC absorber itself affects the normal operation of the system to a certain extent.In this paper, group-cracking and oil-spilling fault of RC absorber in a 220kV transformer substation is on-site inspection, comparison test and disintegration. On this basis, solutions have been proposed, which have a certain significance to solve the group-cracking and oil-spilling fault of RC absorber.
