This unit involves the skills and knowledge required to maintain capacitor bank equipment for voltage regulation in the electricity supply industry (ESI).

It includes maintaining and repairing substation voltage regulating equipment and is restricted to high voltage (HV) capacitor banks and associated switching reactors and the inspection, recording of information, testing and measurement of the associated control circuits. It also includes the range of acceptance tests and discharge requirements for complete units within a substation in accordance with industry standards and workplace procedures, fault diagnosis and return to service tests and interpretation of test results against agreed specifications.

The application of the skills and knowledge described in this unit may require a licence/registration to practice in the workplace.

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