适用范围：1.1 This standard covers the method of measurement of partial discharges in current and voltage transformers.1.2 The capacitive part of capacitive voltage transformers should be tested according to IS : 9348-1979〓.1.3 The minimum voltage levels for which this standard applies are as follows:a) solid insulation : Um — 7.2 kV,b) liquid immersed insulation : Um = 72.5 kV, Um = highest voltage for equipment.1.4 This standard can be applied to unconventional systems ( for example, gas-filled or gas-immersed ) for which less experience is avail-able than for the conventional systems, but their permissible discharge levels shall be subject to agreement between manufacturer and customer.
