Unit 1185, Prepare electrical machines for rewinding
Unit 19470, Rewind electric machines
Unit 19471, Reassemble and test electric machines following rewinding.
Reinstallation and commissioning are covered in:
Unit 2014, Overhaul a.c. rotating machines and control equipment
Unit 5928, Overhaul d.c. rotating machines and control equipment.

Evidence requirements
1.1
Tests are carried out in accordance with industry practice.
tests – continuity of supply conductors, insulation resistance
between windings and earth, resistance of windings; growler test
on machines containing armatures.
Range
1.2
Results of tests are recorded in accordance with company requirements.
Outcome 2
Locate and diagnose faults in electrical machine windings.
Range
faults – open circuit, short circuit, leakage to earth, differences in readings
between windings.
Assessment must involve at least one of each type of fault, real or simulated.
Evidence requirements
2.1
Test results are interpreted and faults located in accordance with industry
practice.
2.2
Likely cause of fault is diagnosed from test results and visual inspection.
2.3
The machines are tagged and documentation completed in accordance with
company requirements.

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 (CMR). 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.
