Explanatory notes
1
The scope of the technology is a combination of the concepts specified in the range
statement of Outcome 1 and the applications specified in the range statement of
Outcome 2. It is expected that the assessment processes and evidence
requirements will consider how to use the outcome ranges together.
2
The following apply to the performance of all outcomes of this unit standard:
a
all measurements are to be expressed in Systeme International (SI) units, and,
where required, converted from Imperial units into SI units;
b
all activities must comply with: any policies, procedures, and requirements of
the organisations involved; the ethical codes and standards of relevant
professional bodies; and any relevant cultural, legislative and/or regulatory
requirements, which can include but are not limited to The Treaty of Waitangi,
the Health and Safety in Employment Act 1992, the Electricity Amendment Act
2006, and their subsequent amendments.

This unit standard replaces the requirements of the New Zealand Certificate of
Engineering (NZCE) modules 5279, Power distribution, and 5280 Generation and
transmission.
4
Performance and work practices in relation to the outcomes and evidence
requirements must comply with all current legislation, especially the Electricity
Amendment Act 2006, and any regulations and codes of practice recognised under
that statute; the Health and Safety in Employment Act 1992; and the Resource
Management Act 1991. Electricity supply industry codes of practice and documented
industry procedures include the Safety Manual – Electricity Industry: Requirements
for Safety in the New Zealand Electricity Generation, Transmission and Distribution
Industry (SM-EI) (Wellington: Electricity Engineers’ Association, 2004). A full list of
current legislation and industry codes is available from the Electricity Supply Industry
Training Organisation, PO Box 1245, Hamilton 3240.

The outcomes of this unit standard are equivalent to the learning outcomes of the
New Zealand Board of Engineering Diplomas (NZBED) course component DE6401
Power Systems 1 Level 6. If a candidate has completed the NZBED course
component related to this standard then they can apply to the ITO for Recognised
Prior Learning (RPL). Further information about this process may be obtained from
the Electricity Supply Industry Training Organisation, PO Box 1245, Hamilton 3240.
Outcomes and evidence requirements
Outcome 1
Describe the given concepts in electricity power transmission technology.
Range
concepts – comparison of the methods of neutral earthing, characteristics and
operation of overhead lines and power cables for 11kv and higher voltages; the
process of current interruption, parameters of current interruption oscillograms;
current making and breaking capacities of various load switches and
disconnectors; surge protection and over voltage protection; causes of faults
and their effect on electrical equipment, symmetrical and asymmetrical faults;
protection systems and function, protection discrimination, key components in
protection systems; current and voltage transformers construction and
functions; metering methods and standards used in distribution industry; power
factor correction; network configuration and analysis; substation arrangements;
national and regional control centres and their function; HVDC Inter Island link
and function in national grid; New Zealand wholesale electricity market and
electricity tariffs.

Please note
Providers must be granted consent to assess against standards (accredited) by NZQA,
before they can report credits from assessment against unit standards or deliver courses
of study leading to that assessment.
Industry Training Organisations must be granted consent to assess against standards by
NZQA before they can register credits from assessment against unit standards.
Providers and Industry Training Organisations, which have been granted consent and
which are assessing against unit standards must engage with the moderation system that
applies to those standards.
Requirements for consent to assess and an outline of the moderation system that applies
to this standard are outlined in the Consent and Moderation Requirements (CMRs). The
CMR also includes useful information about special requirements for organisations wishing
to develop education and training programmes, such as minimum qualifications for tutors
and assessors, and special resource requirements.
