National Certificate in Electricity Supply (Sub Station Maintainer) (Level4)
Level 4
Credits 140
Purpose
This national certificate is awarded to people who have demonstrated competence in the skills and knowledge required for employment in the electricity supply industry as a Sub Station Maintainer. It provides entry into the National Diploma in Electricity Supply (Level5) [Ref: 0674].
It caters for trainees within this industry whose primary role is carrying out maintenance activities on the primary plant and equipment installed in high voltage electricity sub stations.
Holders of the qualification will be able to:
· Joint electricity network overhead conductors
· Carry out in-service visual inspections on sub station equipment and auxiliary plant
· Carry out routine inspections and servicing of power transformers, distribution power transformers, high voltage minimum and bulk oil circuit breakers, pole mounted re-closer circuit breakers, high voltage indoor metal clad circuit breakers and bus
· Carry out routine inspections and servicing on sub station emergency and security services
· Install sub station earthing and bonding system
· Carry out routine service on instrument transformers, and routine inspection and minor servicing on high voltage SF6 outdoor circuit breakers
· Service and repair high voltage disconnectors, earth switches and bus equipment
· Apply and remove safety measures in an electricity supply environment
· Use and maintain test instruments used within the high voltage electrical industry.
· Carry out insulating oil sampling and voltage breakdown tests.
The qualification contains unit standards that build on the knowledge and skills recognised by the National Certificate in Electricity Supply (Electrical) (Level 4) [Ref:0921], National Certificate in Electricity Supply (Mechanical Fitter) (Level 4) with strands in Hydro, Networks, and Thermal; and an optional strand in Electrical Services [Ref:0918], and National Certificate in Electricity Supply (Electrical Services Technician) (Level 3) [Ref:1098].
