This code of practice specifies the procedures and standards to be adhered to by electricity licensees and their agents in operating and servicing new and existing metering installations which are to be used for billing purposes. The code of practice is applicable to metering installations in their entirety, including all measuring transformers, wiring, cabling, metering panel construction, active and reactive meters, data loggers, and associated test facilities.
2 This code of practice sets out best practices to be adopted by electricity licensees, wherever practicable. (See NOTES 1 and 2.)
NOTE 1 Some requirements might be the subject of mandatory compliance through reference In codes regulated by the NER. In cases where compliance with mandatory requirements will not be practicable, the NER should be approached for exemption.
NOTE 2 This code of practice should be interpreted as applicable to new and refurbished metering systems. Practices in place before the publication of this code of practice might be deemed to be acceptable for an agreed time frame.
3 This code of practice specifies requirements for the initial calibration and certification of metering equipment and compliance testing of metering installations. It describes procedures to ensure that metering installations continue to comply with standards and sets out steps to be taken to reconfirm compliance after any modifications to the metering installation or when certification of any equipment has expired.
4 This code of practice specifies procedures for the manipulation and storage of metering data. Metering installations are categorized, and for each category the qualifications required for meter workers are specified.
5 This code of practice specifies a standard format for the unique numbering of meters.
6 This code of practice does not attempt to cover all possible variations in metering installations. Where features additional or alternative to those specified in this code of practice are required, they will be appropriately tested or inspected (or both) to confirm the integrity of the overall metering installation.
NOTE This code of practice does not specify procedures and standards for prepayment metering installations; these are under consideration.
