Dismantle substation plant and apparatus in the power industry
Overview
This standard is about dismantling plant and apparatus in substations in an electricity power utilities environment. 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 and instructions, carrying out risk assessments, checking the system is safe to work on, dismantling plant and apparatus, testing before, during and after dismantling, checking completed work, completing documentation and confirming installation meets safety requirements before energisation.
This standard is for crafts persons or technicians working for network owners or operators or their sub-contractors who are responsible for dismantling plant and apparatus in substations 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 the 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 and instructions about dismantling 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 substation plant and apparatus dismantling activity to affected parties and designated people when required and in line with organisational procedures
use approved tools, equipment and consumables to dismantle substation plant and apparatus in line with organisational procedures
work in line with health and safety, environmental and other relevant regulations, directives and guidance at all times
dismantle substation plant and apparatus in line with workplan, safety instructions and organisational procedures
carry out testing procedures before, during and after dismantling activity in line with organisational procedures
store dismantled plant and apparatus in line with organisational procedures until it can be removed or disposed of
check dismantled plant and apparatus complies with organisational specifications and no damage has occurred to nearby plant and apparatus
complete documentation for substation plant and apparatus dismantling activity in line with organisational procedures
confirm dismantled plant and apparatus meets safety requirements before energisation of neighbouring 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
Knowledge and Understanding
You need to know and understand:
Electrical power principles including three phase alternating current and direct current theories; voltage; dynamic and static engineering systems; application of electrical and electronic circuit theory and interfaces between the system voltage
Electricity network design, construction, capabilities, complexities, operations, boundaries, topologies and control boundaries
Apparatus which makes up the transmission or distribution network and the design, operation, function and limitations of transmission or distribution plant and equipment, substations, transformers, overhead lines, switchgear and auxiliary equipment
Standard terminology, abbreviations and nomenclature in relation to substation plant and apparatus and identification and dismantling techniques
The regulatory requirements associated with safety while carrying out work associated in power networks on substation plant and apparatus
How to assess the location and structure and safe procedures for access, egress and proximity to live equipment
The general and inherent dangers of working with electrical systems of different voltages under outage and non-outage conditions and required measures to address them
Organisational procedures and safety instructions for receiving and confirming operational, network related instructions in normal and fault conditions, including remote and emerging technological advances
The principles of pre task and point of work dynamic risk assessment, when they are required and how to carry them out and record findings
Operational restrictions, their purpose and actions to be taken and how to recognise and use physical signage and network diagram indicators
Who to notify about network related operations, when to notify them and organisational procedures for doing so
Electricity network principles of operation of substations in normal and fault conditions and associated protective devices and their indicators in the event of system fault scenarios
Sources of system information and how to interpret them to identify points of isolation and earthing arrangements including system diagrams, work instructions, fault logs, protection data
The sequence of processes, procedures, stages and operational safety rules relating to dismantling activity
The environmental impact of disposal, organisational decontamination procedures and what to do if things go wrong, including the use of spill kits
The approved plant, apparatus, tools and consumables required for substation plant and apparatus installation and how to obtain, inspect, prepare, carry out pre-use checks, use, maintain and store them
Temporary or standby auxiliary supplies, when they are required and how to use them
How to dismantle plant and apparatus including transformers, switchgear, package substation, low voltage frames, panel wiring, batteries and chargers, cables, low voltage apparatus, automation equipment, switchgear housing, busbars, circuit breakers, isolators, compressed air equipment, neutral earthing resistors, interrupter heads, TX dehydration and other bespoke equipment
Processes to follow to prevent damage to plant and apparatus being dismantled and nearby plant and apparatus
How to identify plant, apparatus and components that are re-useable and those that require disposal
Organisational procedures and designated areas for storing dismantled plant, apparatus and components prior to disposal or long-term storage
Safety, earthing and bonding materials and where and when they should be applied
The purpose of checks and tests for substation plant and apparatus, when they are required and how to carry them out including visual checks, functional checks, electrical tests
Organisational procedures and systems for recording and storing operational information and to meet cybersecurity and data governance requirements, including role-based access, secure storage, audit logging, data retention
The route to authorisation and supervision at different levels and the training, experience and certification required for your role
