Network Access and Switching Authorities

The information on this webpage is designed to provide established Network Operator Switching Classes and Network Access Forms including VESI Authorisations for personnel who are required to access Victorian Distribution Networks assets. These Classes are mutually recognised between the 5 Distribution Network Operators and meet the requirements of the Green Book which describes the Electrical Safety Rules for Victorian Distribution Networks.

For specific access requirements to the Network operators please refer to the Network operator responsible person.

Purpose

Network access procedures in Victoria are established in accordance with the VESI Green Book which describes five Authority types:

  • Receive Access Permits
  • High Voltage Switching
  • Enter Enclosures
  • Make Application for; and
  • Receive Sanction for Test

These Authorities allow network operators and their contractors to plan, perform and test work. For detailed information regarding network access, persons should refer to the VESI Green Book.

There is no charter for this work, is this is performed by a working group as a sub-committee of the Skills and Training Reference Committee.

Committee Members

Membership of the Network Access working group is made up of the following VESI employees:

VESI - HIGH VOLTAGE SWITCHING AUTHORITY CLASSES

The Victorian Electricity Supply Industry (VESI) High Voltage Switching Authority Classes are agreed HV Switching classifications which are mutually recognised between Network Operators. The classifications are based on the basic principles of operating and may have restrictions placed on them by the issuing Network Operator. Such restrictions may typically be geographical or itemised plant and shall be recorded in the Network Authority section of the Australian Skills Passport. Where necessary, inductions may be undertaken by a Network Operator.

Training Modules for these Authorities can be viewed at the Skills and Training webpage by clicking here

Log Books

VESI Log Books have been developed for RSO, DS, DSO and ZSS Switching. These Log Books will assist the trainee in documenting evidence of the practical (on the job) component of HV Switching to enable them to be assessed for authorisation.

The Log Books available in the links below are a sample only and are not to be used. Log Books can be requested from each Network Operator.

Network Access

The following Network Access forms are mutually agreed by the Victorian Electricity Supply Industry (VESI) to ensure consistency across all Network Operators.

The forms are a sample only and not to be used. Books of the forms can be obtained from each Network Operator.
