ABSTRACT:
After removing foreign matters on surfaces of joint portions of two members of a potential transformer, a first sealing agent obtained by mixing liquid A including an epoxy resin as a main component and liquid B including liquid polymercaptan as a main component is coated on the cleaned surfaces and hardened. A second sealing agent obtained by mixing liquid C including an epoxy resin as a main component and liquid D including liquid modified polyamine as a main component may be applied to the hardened first sealing agent, so that oil contained in the potential transformer can be positively prevented, and, at the same time, repairing work of a portion where oil leaks can be easily and quickly carried out.
