The National Cleaner Production Centre South Africa (NCPC-SA) aims to raise awareness of the importance of Power Quality in the manufacturing industry at this year’s Africa Energy Indaba (AEI).

Power Quality refers to the degree to which a power system conforms to established standards; in the South African context the standard is NRS048. It refers to voltage, waveform, and frequency parameters of power, and deviations in these parameters affect equipment connected to the power system in its ability to function properly.

The NCPC-SA is a programme of the Department of Trade Industry and Competition and is hosted by the Council for Scientific and Industrial Research. It is a national support programme that drives the shift towards a green economy through resource efficiency and cleaner production interventions in South Africa.

“Power Quality is relevant for South Africa as the country moves from coal-fired thermal power towards renewable energy generation,” says NCPC-SA quality assurance manager Tanya van Zyl.

She explains that local Power Quality issues arise because of solar photovoltaic and wind power generation; the proliferation of non-linear loads, such as variable-speed drives and light emitting diode lighting; larger loads, such as electrical arc furnaces; and natural causes of voltage dips, including lightning strikes.
