NZQA Expiring unit standard 19325 version 6 Page 1 of 4 Title Demonstrate knowledge of the fundamentals of electricity generation in New Zealand Level 3 Credits 3 Purpose People credited with this unit standard are able to: demonstrate knowledge of the principles of electricity generation; and the types of electricity generation in New Zealand. Classification Electricity Supply > Electricity Supply - Core Skills Available grade Achieved Explanatory notes 1 This unit standard is intended for, but not restricted to, workplace assessment. The range statements across the unit standard can be applied according to industry specific equipment, procedures and processes. 2 Performance and work practices in relation to the outcomes and evidence requirements must comply with all current legislation, especially the Electricity Act 1992, 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 current version of the Safety Manual – Electricity Industry (SM-EI) (Wellington: Electricity Engineers’ Association). A full list of current legislation and industry codes is available from the Electricity Supply Industry Training Organisation, PO Box 1245, Waikato Mail Centre, Hamilton 3240. 3 4 This unit standard is The phrase in accordance with industry requirements is implicit in all outcomes and evidence requirements in this expiring unit standard. Industry requirements include all industry and workplace documented policies, procedures, specifications, and business and quality management relevant to the workplace where assessment is carried out. Infrastructure ITO SSB Code 101813 New Zealand Qualifications Authority 2016 NZQA Expiring unit standard 19325 version 6 Page 2 of 4 Outcomes and evidence requirements Outcome 1 Demonstrate knowledge of the principles of electricity generation. Range conservation of energy, magnetic field and current relationships. Evidence requirements 1.1 The effect of current carrying conductor is explained in terms of magnetic field present around conductor. 1.2 The effect of passing current through conductor in magnetic field is explained in terms of force moving a conductor across field flux lines. 1.3 The effect on conductor forced through magnetic field is explained in terms of current induced in conductor. 1.4 The concept of electromagnetic fields is explained in terms of magnetic field effect of conductor coil. 1.5 Simple AC generation by field rotation is explained in terms of rotating field and electromagnetic force induced in stator winding. 1.6 Commutation and DC generation are explained in terms of field, electromagnetic force induced in rotating winding, commutator and brushes to provide unidirectional output. 1.7 The effect on the generated electromotive force of varying the current in the electromagnetic field coils in a generator is outlined in terms of flux increased, induced voltage increased. 1.8 The effects of balance and imbalance between generator power output and load power consumption are explained in terms of rotational speed constant, increases or decreases. 1.9 The concept of an infinite busbar is explained in terms of constant system frequency and voltage. 1.10 The effects of varying the magnetic field and generated power with generator connected to infinite busbar are explained in terms of current leads or lags system voltage, generator accepts greater or lesser load. 1.11 The concepts of single phase and three phase generation are explained in terms of single set of waveforms, three sets of waveforms and 120º displacement.

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.
