Unit Of competency

Modification History

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

Application

This unit involves the skills and knowledge required to perform straight through high voltage (HV) paper insulated cable to polymeric transition joint cable in the electricity supply industry (ESI).

It includes the formation of a HV/low voltage (LV) transition joint(s) from paper insulated to polymeric cable on belted and screened cables, the determination of electrical values of belt papers and core insulation, protection of core and belt papers prior to setting, core setting, termination of belt papers, construction of bell mouth and moisture testing.

It also includes isolation of systems and circuits, the procedures of issuing/accepting electrical access permits, undertaking pre-commissioning and/or re-commissioning tests and updating system data/maintenance records.

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.
