Release 1. This is the first release of this unit of competency in the UET Transmission, Distribution and Rail Sector Training Package Release 4.0.

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

It includes different capacitor bank types, characteristics, isolation and discharge, maintenance requirements, common defects and rectification.

It also includes ancillary components of capacitor banks, testing requirements and the use of specialised tools and equipment.

Note: Entry into this unit is for users who:

• hold the unit UETDREL005 Work safely in the vicinity of live electrical apparatus or equivalent,

and

• hold an Electrician licence or the equivalent issued in an Australian state or territory,

or

• hold an Electrician qualification or the equivalent issued in an Australian state or territory.

This unit can be undertaken in conjunction with the qualification listed above, provided all requirements for completion of the Certificate III qualification are met prior to issuing this unit.

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

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