Transcription

1 Power Unit 78 Install Substation Switchgear The specification details the required skills, knowledge and behaviours to establish competence to carry out the installation of electricity switchgear. The specification details the requirements for THREE separate categories. Candidates may be assessed and receive registration for any ONE or a COMBINATION of the following: 1. Transmission Switchgear 2. Primary Switchgear 3. Distribution Switchgear (up to 20 kv) This specification details the minimum skills, knowledge and behaviours that would be required by a candidate to be assessed as competent. This does not preclude employers adding to the skills and knowledge detailed by the specification in their own training programmes. What does competence look like? SGM1 Being able to confidently use tools and equipment to carry out a range of maintenance procedures on switchgear in a substation environment in accordance with Company procedures SGM2 Demonstrating a safety conscious approach to the control of hazards associated with the activity whilst working and communicating effectively with other team members to achieve tasks Achievement of each modules performance criteria should be gained over a period of time by carrying out a range of installation activities on differing types of equipment. What do I need to take this module? Candidates to be assessed as competent in this skill area shall have completed the modules shown below or have evidence demonstrating an equivalent level of competence. 078 October 2015 V1 Page 1
