Complete guide to IEC 61869 compliant high accuracy current transformers for electrical metering. Learn about accuracy class CTs, LPCT technology and Australian industry compliance requirements.

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.

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.

SATEC Australia’s Engineering Manager, Marcelo Silva had the pleasure of working with the NSW Department of Planning, Industry and Environment to produce the Electricity Metering and Monitoring Guide.

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.

Electricity meters come in many forms. Understanding features and capabilities, as well as the requirements of an application, can ensure that today’s meter will meet tomorrow’s requirements.

Days of analogue instruments are fading, as is the use of ‘pulse only electrical meters’, or to the lesser extent, real-time-meters without internal memory and an internal clock. The evolution of multi-function electrical meter sees a wide gap in technology by vendors.

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.
