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 (see annex F).
Diagnosis of the behaviour of specific power apparatus can be aided by digital processing ofpartial discharge data (see annex E) and also by non-electrical methods that are primarilyused for partial discharge location (see annex F).
This standard is primarily concerned with electrical measurements of partial discharges madeduring tests with alternating voltage, but specific problems which arise when tests are madewith direct voltage are considered in clause 11.
The terminology, definitions, basic test circuits and procedures often also apply to tests with other frequencies, but special test procedures and measuring system characteristics, which are not considered in this standard, may be required.
Annex A provides normative requirements for performance tests on calibrators.
