High Voltage Auditing

High Voltage Auditing

High Voltage Auditing

A High Voltage Audit is an independent and final step in the design and construction process for new electrical installations or an existing electrical installation that has had electrical installation work performed on it.

Protech PAS provides accredited HV Auditors to carry out an audit of a new or altered high voltage installation as per the requirements of the Electrical Safety Regulation 2013 in Queensland.

This is done by determining and requesting the required documentation for review and conducting a physical inspection of the new or altered high voltage installation after the electrical work has been performed.

An energization clearance authority is issued once the documentation review and site inspection is deemed to be compliant with the relevant standards.

High voltage is defined as greater than 1000V AC RMS or 1500V ripple-free DC

Section 221 of the Electrical Safety Regulation 2013 requires that an accredited auditor inspect high voltage electrical installations prior to connection or reconnection to a source of electricity, if:

Section 221 of the Electrical Safety Regulation 2013 requires that an accredited auditor inspect high voltage electrical installations prior to connection or reconnection to a source of electricity, if:

  1. The high voltage electrical installation is being connected for the first time
  2. Electrical installation work has been performed on the HV electrical installation.

The owner of the high voltage installation must ensure that:

  1. The installation is inspected, tested and found to be electrically safe by an accredited auditor before the installation is connected or reconnect to the electricity supply; and
  2.  All requirements, as stipulated by the accredited auditor, are met and are maintained during the life of the installation.

A pre-commissioning inspection ensures that the installation, related electrical equipment and protective equipment have correct certification and comply with certification documentation and appropriate standards.

Protech PAS Queensland Government accredited high voltage auditor will provide an independent review of our customer’s high voltage installations, protection and other high voltage equipment.

A HV Audit Report will be provided that will advise customers on how to rectify any areas of non-compliance, remedial actions required and other compliance information. All new or modified installations must have a high voltage audit completed to comply with the Queensland Electrical Safety Act.

Periodic Audits are the best way to ensure that electrical installations continue to meet safety requirements and ensure both plant and workers remain as safe as possible.

Failure to adhere to the obligations under part 27 regarding the Electrical Safety Act 2002 may end in legal proceedings that may include charges up to $1,000,000 ($200,000 for an individual) or three years imprisonment.

Under area 153 of the Electrical Protection Regulation 2002, a person must not connect or reconnect a top voltage electrical installation as a way to obtain electricity, after electrical work has been performed on the installation, unless the electric work was inspected by a certified auditor and found to be electrically safe and compliant with the Wiring Rules (AS/NZS 3000) and other relevant Australian standards, such as AS2067 (Substations and high voltage installations surpassing 1 kV AC).

More Information

In Queensland under Section 221 of the Electrical Safety Regulation 2013, a person must not connect or reconnect a high voltage electrical installation to a source of electricity, after electrical work has been performed on the installation, unless the electrical work has been inspected by an accredited auditor and found to be electrically safe and compliant with the Wiring Rules (AS/NZS 3000) and other relevant Australian standards.

The accredited HV auditor is an independent and the final step in the design and construction process. By conducting a documentation review and physical inspection of the works, they can identify potential safety concerns with the design, installation or testing phases of the electrical works. Identifying these issues may significantly reduce or eliminate the cost of death and injury to individuals, families and the community and destruction of equipment that could be caused by the normal or abnormal operation of the high voltage equipment once energized or reenergized.

Owners of high voltage installations also have a legislative responsibility to ensure safe operation of their high voltage infrastructure. HV audits, regular inspections, carefully tailored maintenance strategies and frequencies will prolong the lifetime of the high voltage equipment while correct and detailed operating procedures and documentation will ensure a safe working environment for operators and people working in the vicinity of the high voltage equipment.

Other HV audits we can provide include:

HV equipment general health check and maintenance and maintenance frequency recommendations.

HV equipment engineering audit for the more complex studies such as equipment operation analysis, equipment fault protection adequacy, earth grid adequacy, predicted life cycles of equipment, and identifying harmonic issues.

HV equipment compliance for older installations or equipment not necessarily covered in Section 221 of the Electrical Safety Regulation 2013.
