This Malaysian Standard specifies the measurement of partial discharges which occur in electrical apparatus, components or systems when tested with alternating voltages up to 400 Hz or with direct voltage.
This standard
–defines the terms used;–defines the quantities to be measured;
–describes test and measuring circuits which may be used;
–defines analogue and digital measuring methods required for common applications;
–specifies methods for calibration and requirements of instruments used for calibration;
–gives guidance on test procedures;
–gives some assistance concerning the discrimination of partial discharges from external interference.
The provisions of this standard should be used in the drafting of specifications relating topartial discharge measurements for specific power apparatus. It deals with electricalmeasurements of impulsive (short-duration) partial discharges, but reference is also made tonon-electrical methods primarily used for partial discharge location
