Is applicable to devices and to complete measuring systems used for the measurement of very fast front overvoltages generated by switching or due to disruptive discharge within gas-insulated metal-enclosed substations. The procedure to evaluate the uncertainty on the measurement described applies to test levels of internal fast front overvoltages stated in IEC 1259. Defines the terms used,describes the characteristics of very fast front overvoltages, gives the requirements for measuring systems, describes some possible measuring systems, describes calibration procedures.
