Transcription

1 Page 1 of 5 Title Install high voltage (HV) electricity network overhead conductors Level 4 Credits 8 Purpose People credited with this unit standard are able to: interpret scope of work for installing high voltage (HV) electricity network overhead conductors; string electricity network HV conductors; tension and terminate electricity network conductors; install and attach electricity network conductors to line hardware; conduct pre-commissioning checks and tests on overhead conductors; and report work done on HV electricity network overhead conductor installation; in accordance with industry requirements. Classification Electricity Supply > Electricity Supply - Distribution Networks Available grade Achieved Entry information Critical health and safety prerequisites Unit 10509, Climb and work on electricity network structures; Unit 28112, Operate and store machinery, plant, and equipment in an electricity network environment; and Unit 10512, Joint electricity network overhead conductors; or demonstrate equivalent knowledge and skills. Explanatory notes 1 This unit standard is intended for, but not restricted to, workplace assessment. The range statements within the unit standard can be applied according to enterprise specific equipment, procedures and processes. 2 Safety of personnel and plant must be a priority throughout the assessment. If the safety requirements are not met the assessment must stop and the candidate will be assessed as not yet competent.

These include, Safety Manual Electricity Industry (SM-EI) (2004) Wellington: Electricity Engineers Association. A full list of current legislation and industry codes is available from: PO Box 1245 HAMILTON. 4 The phrase in accordance with industry requirements is implicit in all outcomes and evidence requirements in this unit standard. 5 Definitions 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. 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. Asset owner standards are the approved documented work site methods for carrying out work on an electrical supply network to the standard required by the asset owner. 6 This unit standard is intended for use in the assessment of Distribution and Transmission Line Mechanics and all terminology should be related to that sector of the industry. 7 Assessment of practical skills against the outcomes in this standard requires three practical observations from three different workplace activities. Outcomes and evidence requirements Outcome 1 Interpret scope of work for installing HV electricity network overhead conductors. 1.1 Conductor requirement is established. size, type. 1.2 Structure arrangement and type is established. 1.3 Installation work plan and method are established.

3 Page 3 of 5 may include but is not limited to equipment location, protection of equipment, pull length, rigging set up, structure access, safety considerations; evidence of four is required. 1.4 HV conductor sag tension is established. sag charts, clearances, line configuration, structure type, loadings. Outcome 2 String electricity network HV conductors. 2.1 Conductors are handled. 2.2 Conductors are installed. electrical protection, mechanical protection, manufacturer s specifications, safety considerations. Outcome 3 Tension and terminate electricity network conductors. 3.1 Conductors are installed to specified sag and tension requirements. may include but is not limited to sag charts, visual sag, clearances, line configuration, loadings of structures, asset owners specifications; evidence of two sources is required. 3.2 Conductors are terminated in dead end. binding, chafers, clamp, compression, preformed; evidence of two methods is required. Outcome 4 Install and attach electricity network conductors to line hardware. 4.1 Conductors are attached to insulators. binding, chafers, clamp, compression, preformed; evidence of two methods is required. 4.2 Construction earths are connected to structure hardware.

4 Page 4 of Conductor hardware is attached. includes but is not limited to armour rods, jumpers; evidence of two is required. Outcome 5 Conduct pre-commissioning checks and tests on overhead conductors. 5.1 Visual checks are conducted. includes but is not limited to connections, hazards. 5.2 Tests are carried out. includes but is not limited to voltage, polarity, phase rotation. Outcome 6 Report work done on HV electricity network overhead conductor installation. includes but is not limited to electric line history, test reports and results, service report, work report; evidence of one type of report is required. 6.1 Reported information is complete, concise, and legible. 6.2 Information is recorded in the required company or asset owner s format and filed within the scheduled time-frame.

5 Page 5 of 5 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.
