10. HIGH VOLTAGE ELECTRICAL WORK

Requirements for electrical work on high voltage equipment after switching, isolation, short circuiting and earthing are specialised requirements. Only competent electrical workers who have received appropriate training in high voltage electrical work are permitted to work on high-voltage electrical equipment.
For more information you should seek further advice about working on or near high-voltage electrical installations from a specialist electrical contractor or the local electricity supply authority.

Additional risks associated with high voltage
The electrical risks and consequences of an electrical incident involving high voltage may be significantly higher than low voltage. Under fault conditions, the higher voltages (potentials) and fault current levels release massive quantities of energy. These risks must be effectively managed.

Planning for high voltage installation work
Persons conducting a business or undertaking who have a high voltage electrical installation should prepare an Installation Safety Management Plan for their workplace. The plan should address the risks associated with the operation and maintenance of the high voltage installation.
This may include:
    * a single line diagram for the installation, showing all switches and circuit breakers and their identifying labels or numbers
    * site-specific operating rules covering all aspects of operating the high voltage installation, including procedures for arranging isolation of the installation from the local electricity network
    * procedures for identifying hazardous areas including any confined spaces associated with the installation
    * competency requirements for persons who may be permitted to operate or work on the high voltage installation, including appropriate requirements for re-training, re-testing and re-accreditation
    * induction procedures for new contractors
    * regular inspection and maintenance programs to ensure the installation remains serviceable and safe
    * procedures for ensuring there is no extension or alteration of the installation without permission from the local electricity supply authority
    * procedures for the safe handling of insulating oils and other substances that may be required for maintenance or repair
    * procedures including warning signs for ensuring that all parts of the high voltage installation (e.g. underground cables and high voltage overhead power lines) are not damaged by heavy vehicles or other mobile plant, for example mobile cranes.

APPENDIX A – MEANING OF KEY TERMS
Competent person means:

    * for electrical work on energised electrical equipment or energised electrical installations (other than testing referred to in Regulations 150 and 165), a licensed or registered electrician or any other person permitted to carry out or supervise electrical work under relevant State or territory legislation (e.g. electrical engineer, electrical apprentice)
    * for any other case, a person who has acquired through training, qualification or experience and the knowledge and skills to carry out
