1. Introduction IEC 60060 is a pivotal standard published by the International Electrotechnical Commission (IEC) . It defines the procedures, equipment, and acceptance criteria for dielectric tests on high-voltage (HV) equipment. The standard ensures that electrical apparatus such as transformers, circuit breakers, cables, insulators, and switchgear can withstand the electrical stresses encountered during normal operation and transient overvoltages. iec60060
