Description

This unit provides the skills and knowledge to perform high-voltage switching on Sub-Transmission and Distribution apparatus within zone substations. It covers Green Book principles, roles and responsibilities, operational procedures, hazard identification, safe work practices, PPE use, earthing procedures, communication protocols, and emergency response. Participants will learn to interpret HV single line diagrams, conduct systematic switching, operate HV switchgear safely, issue and cancel Electrical Access Authorities, and manage faults and protection systems.

Prerequisites

UETDRSB001 – Perform substation switching operations to a given schedule.

Course aim

On completion, learners will have the knowledge and skills to perform High Voltage Electrical Switching on all Sub-Transmission and Distribution apparatus within zone substations.

Target learner group

For persons who are required to work on, near or in the vicinity of the electricity network assets

Learning activities

Delivery mode

  • Face-to-face led training
  • Theory assessment

Learning outcomes

After successfully completing this unit, a learner should be able to:

  • Locate, interpret, and apply appropriate Regulations, The Green Book and Network Operators switching procedures relating to HV electrical safety.
  • Identify the function, operation, and precautions associated with high voltage electrical apparatus and associated hardware.
  • Interpret HV single line diagrams and prepare a switching program.
  • Demonstrate switching processes, procedures and communication protocol for the safe switching of Zone Substations.
  • Demonstrate effective communication protocol and earthing practices and procedures when earthing HV electrical apparatus for access.
  • Describe the purpose, preparation, and procedure for use of operational forms, access authorities and permits associated with HV switching.
  • Issue and cancel access authorities appropriate to the nominated tasks.
  • Describe the functions and operation of common high voltage protection systems and suppression functionality.
  • Identify the requirements for identifying and switching the HV network in fault situations

Assessment approach

Learners are assessed using the following methods

  • Theory and written assessments.
  • Direct observation and practical assessment.

Course entry requirements

Learners in this course are required:

  • To have basic literacy and numeracy skills so learners can understand the theory and assessments.
  • Hold the current certification in the required prerequisites.
  • Be sufficiently fit to participate in training. (especially if there are physical elements or field-work context)

Accreditation status

On successful completion of this course, learners will receive a completion certificate.

Equipment & PPE

Learners are required to have the following Personal Protective Equipment:

Safety helmet, safety footwear, high-visibility clothing, safety glasses and insulated gloves.
