This unit covers the testing and maintenance of energy/revenue metering schemes in complex situations. Complex metering schemes include summation, subtraction, generation, bulk supply, interconnector and wholesale metering installations. Testing and maintenance include isolation, accuracy testing, inspection, monitoring, adjustment, repair or overhaul and functional checks of complex energy/revenue metering schemes.

It includes the requirements to prove the functionality of the metering scheme in accordance with electrical installation (state and national) standards, metrology procedures and compliance to tariff requirements.

This also includes the identification of faults with metering equipment, energy registration and revenue billing in accordance with established procedures.

The application of the skills and knowledge described in this unit requires a licence/registration to practice in the workplace subject to regulations for undertaking of electrical work.

Other conditions may apply under state and territory legislative and regulatory licencing requirements which must be confirmed prior to commencing this unit.
