Industry requirements include all asset owner requirements; manufacturers’
specifications; and enterprise requirements which cover the documented workplace
policies, procedures, specifications, business, and quality management requirements
relevant to the workplace in which assessment is carried out.

The following terms and abbreviations relate to this unit standard:
Asset owner refers to the owner of an electricity supply network that takes its point of
supply from Transpower NZ and delivers electricity to industrial, commercial and
residential customers.
Data refers to information in a written or numerical form. The latter may include
summary statistics, information in tables and numbers displayed in a variety of
graphs.
Switching plan (sometimes referred to as an operating order) is a document that
outlines the sequence of work steps, switching requirements, and instructions
required to carry out maintenance, replacement, and/or repair of equipment on an
electrical network.
Power system events are routine occurrences that threaten the operational efficiency
and performance of power system components, electrical route ways, circuits, plant,
and equipment, and may pose a threat to the continuity of supply of electricity to
customers.
The terms power network and power system have the same meaning.
SCADA – Supervisory Control and Data Acquisition system used for control,
indication, and monitoring purposes.
7
For this unit standard emergencies may include but are not limited to – volcanic
eruption, flood, landslide, dam break, earthquake, storms, extensive equipment
failure, bomb threat, serious environmental issues, fire, serious accidents, armed
threat, events that seriously threaten the continuity of supply of electricity to
customers.
