Install wood pole overhead line plant and apparatus in the power industry
Overview
This standard is about installing wood pole overhead line plant and apparatus in an electricity power utilities environment. This could apply to new installations or replacement of existing plant and apparatus. This could apply to both electrical transmission or electrical distribution networks and could typically apply to voltages from low voltage up to and including transmission voltages such as 400,000 volts. Networks could be aligned with systems using traditional or emerging energy technologies.
This standard includes confirming safety documents, permissions and instructions, carrying out risk assessments, checking the system is safe to work on, raising and lowering plant, apparatus, tools and equipment, installing plant and apparatus, testing and checking installations and completing documentation.
This standard is for crafts persons or technicians working for network owners or operators or their sub-contractors who are responsible for installing wood pole overhead line plant and apparatus on electrical networks. This could be carried out by people with different levels of network operational authorisation, but in each case, they will be required to have the degree of supervision which is required for their individual level of authority.
Performance Criteria
You must be able to:
identify work location using system information in line with organisational procedures
carry out all work within the remits of own authority and under the supervision of suitably authorised personnel when required
receive and confirm safety documents, land access permission documents and work instructions about installation activities to be carried out in line with organisational procedures
carry out site specific risk assessments of work areas and condition of plant and apparatus to be worked on, identifying hazards and required control measures in line with organisational procedures
check the system is confirmed as safe to work on in line with organisational operational safety rules
communicate the status of overhead line installation to affected parties and designated people when required and in line with organisational procedures
use approved plant, apparatus, tools, equipment and consumables for overhead line plant and apparatus installation in line with organisational procedures
work in line with health and safety, environmental and other relevant regulations, directives and guidance at all times
ensure plant, apparatus, tools, equipment and consumables are raised, lowered and used in accordance with organisational safety procedures
install overhead line plant and apparatus in line with workplan, safety instructions and organisational procedures
carry out testing procedures before, during and after installation in line with organisational procedures
check completed installation complies with organisational specifications and no damage has occurred to overhead line plant and apparatus
complete documentation for overhead line plant and apparatus installation in line with organisational procedures
confirm completed installation meets safety requirements before energisation of new equipment or reenergisation of the network
leave work areas in a safe condition in line with organisational procedures
deal with network issues and complications in line with safety and organisational procedures
escalate issues that you cannot resolve to the designated person in line with organisational procedures when required
