标准摘要
Gives insulation requirements for power transformers and the corresponding insulation tests for specific windings and their terminals. Includes appendices on: partial discharge measurements during induced overvoltage withstand tests on transformers; overvoltage transferred from a high-voltage winding to a low-voltage winding; information to be supplied with enquiries and orders.
