Proposes the adoption of IEC 61000-4-7:1991 which is a guide to instrumentation intended for measuring voltage components with frequencies in the range d.c. to 2500 Hz which are superimposed on the voltage or current at the power supply frequency. It also provides guidance on measurement instrumentation intended for testing individual items of equipment in accordance with emission limits given in Standards as well as for the measurement of harmonic voltages and currents in actual supply systems. Frequency domain instrumentation are both and time considered in this Standard. Proposed as a Joint Australian/New Zealand Standard. Copies of IEC 61000-4-7 may be purchased from or viewed at any Standards Australia office.
