Evidence Required

This provides essential advice for assessment of the unit of competency and must be read in conjunction with the performance criteria and the range statement of the unit of competency and the Training Package Assessment Guidelines The Evidence Guide forms an integral part of this Competency Standard Unit and shall be used in conjunction with all component parts of this unit and performed in accordance with the Assessment Guidelines of this Training Package

Overview of Assessment

Longitudinal competency development approaches to assessment such as Profiling require data to be reliably gathered in a form that can be consistently interpreted over time This approach is best utilised in Apprenticeship programs and reduces assessment intervention It is the Industrys preferred model for apprenticeships However where summative or final assessment is used it is to include the application of the competency in the normal work environment or at a minimum the application of the competency in a realistically simulated work environment It is recognised that in some circumstances assessment in part or full can occur outside the workplace However it must be in accord with Industry and Regulatory policy in this regard Methods chosen for a particular assessment will be influenced by various factors These include the extent of the assessment the most effective locations for the assessment activities to take place access to physical resources additional safety measures that may be required and the critical nature of the competencies being assessed The critical safety nature of working with electricity electrical equipment gas or any other hazardous substancematerial carries risk in deeming a person competent Hence sources of evidence need to be rich in nature so as to minimise error in judgment Activities associated with normal every day work have a bearing on the decision as to how much and how detailed the data gathered will contribute to its richness Some skills are more critical to safety and operational requirements while the same skills may be more or less frequently practiced These points are raised for the assessors to consider when choosing an assessment method and developing assessment instruments Sample assessment instruments are included for Assessors in the Assessment Guidelines of this Training Package

It allows for different work environments and situations that will affect performance. This Competency Standard Unit shall be demonstrated in relation to the inspection, maintenance and restoration of overhead distribution network infrastructure. Inspection may be carried out on foot, and/or by conventional ground-based vehicle, or from the air. Aircraft may be helicopters or fixed-wing types. Inspection techniques include use of X-ray and infrared camera. Items to be inspected may include overhead poles and or structures, but not towers. Types of electrical apparatus to be inspected include overhead conductors and cables, overhead transition points and, electrical equipment such as pole-mounted transformers and air-break switches, hardware, such as insulators, surge arrestors and cross-arms and or earthing systems. The maintenance of overhead energised low voltage conductors and cables must take into account the potential hazards, the calculation of physical loads, including an understanding of the effects of traffic loads and de-rating of circuits. Maintenance may include the removal, repair and replacement of cables, conductors and associated hardware. Structures include poles, and columns. Work methods require the use of insulating gloves and specialised live working equipment and tools. Work may be performed from elevating work platform, ladder, portable pole platform, or the ground. Testing and recording devices include voltage detectors, tong ammeters, polarity testers, recording meters and phase sequence indicators. Specialised live working equipment includes insulating mats and sleeves, insulating gloves, temporary bridges/hoppers, insulated cable tensioning devices and ladder/pole shrouds and equipotential bonding.
