Electrical substation insulator washing

This two-day course provides participants with knowledge and skills of insulator washing principles and procedures, and the skills to wash insulators on energised equipment in electrical substations.

It sets out the minimum standard as detailed in Substation Insulator Washing Maintenance Instruction (DM# 700585). The instruction attempts to ensure the safety of the general public and personnel carrying out this work. The instruction also specifies the minimum standards for equipment required for energised substation washing methods.

This course focuses on all insulator washing work performed by authorised persons on live high voltage apparatus from 6.6 kV up to and including 132 kV, with the same washing principles applied to de-energised washing of 220 and 330 KV terminal station equipment.

Note: To undertake this course the client must provide the necessary plant and equipment on the second day, ie:

  • trigger mechanism fitted with high voltage earth lead and clamp
  • minimum of 450 litre water tank filled with demineralised water at a maximum of 2 ms per/ml
  • high pressure washing unit
  • insulated high pressure hose
  • insulated washing wand
  • silicone wipes
  • an ms water meter
  • a wind meter

Who should attend

This course is suitable for people who are required to be authorised to conduct electrical substation insulator washing on the Western Power network.

Prerequisites

  • Western Australian Electrical Licence or Cert III Distribution Lineworker
  • First Aid certificate (CPR)
  • Substation Entry Level 2
  • Network Authority Card (NAC)

Note: All prerequisites need to be current.

Learning outcomes

As a result of attending this course participants should be able to:

  • identify and apply worksite safety requirements
  • identify and prepare equipment for insulator washing
  • inspect and maintain tools and equipment use for insulator washing
  • test the quality of water used for insulator washing
  • test insulator for defects
  • wash insulators in electrical substations

PPC and PPE requirements

Some of the practical training for this course will take place in an operational area. You are required to have/provide Western Power approved PPC and PPE requirements for the practical work. Refer to the Western Power PPE Procedure Sections 3.1 & 3.2, for these requirements.

Note: Power Training Services does not provide PPE, PPC and tools for training courses.

Assessments

Assessments are included in this course. Participants will not be considered to have completed this course until all assessments have been completed to a satisfactory level.
