This part of NRS 048 specifies the voltage characteristics, compatibility levels, limits and assessment methods for the quality of electricity supplied by South African licensees to end customers. It is intended to provide a) the National Electricity Regulator (NER) with a means of evaluating and regulating the quality of supply (QOS) provided by licensees (see note 1); b) licensees and their customers with a reference for establishing appropriate QOS contracts; c) licensees with QOS standards and criteria for planning, designing, operating and managing their networks; d) customers with standards and criteria for evaluating the QOS delivered by utilities (see note 2), and e) customers and equipment suppliers with standards and criteria to be taken into consideration when designing their plant and specifying equipment. NOTE 1 The annual reporting requirements and system performance criteria for licensees will be specified separately by the NER. It is intended that for the purpose of such reporting, the reporting and assessment methods in this part of NRS 048 will apply at each monitored site. NOTE 2 It is intended that licensees meet the appropriate compatibility levels and limits specified in this part of NRS 048 for each customer.
