As modern electrical grids evolve with the increasing integration of renewable energy sources and the complexities of smart grid technologies, the need for precise and comprehensive power quality (PQ) monitoring has never been greater.

Electricity energy metering accuracy is an important step in ensuring data integrity. Anomalies in measurements can, over a period of time, create hundreds or thousands of dollars in errors.

National Instrument Test Procedures (NITP) form part of the legal quality assurance systems, as mandated by the National Measurement Institute (NMI). NMI works to assure accuracy verification is done for all electricity meters used within Australia for Trade Measurement or Billing. National Instrument Test Procedures for electricity utility meters is known as NITP-14. Electricity metersRead more

The new Power of Choice (PoC) reforms implemented within Australia work to provide benefit to consumers combined with the Australian Energy Market Commission (AEMC) expanding competition in metering and related services review.

Electricity energy meters for use in the Australian market must be Pattern Approved, this involves a process of assessing and testing the electricity energy meter to comply with metrology conditions per NMI M 6-1.

Many sceptics thought it was impossible to achieve NMI Approval for a Multifunction Electricity Meter designed in a compact DIN rail footprint. In fact many doomsday forecasters predicted electrical switchboard enclosures, distribution boards, riser/cupboard spaces for multifunction metering would have to be increased in size to accommodate larger electrical metering to be in compliance for Energy Meters per NMI M 6-1.

Today’s world of electricity measurements is important to ensure various levels of readings are accurate, repeatable for data validation, billing accuracy and assurance of data integrity.
