9) This provides essential advice for assessment of the competency standard unit and must be read in conjunction with the Performance Criteria and the Range Statement of the competency standard unit 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 | 9.1) 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 Industry's 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 substance/material 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. |
Critical aspects of evidence required to demonstrate competency in this unit | 9.2) Before the critical aspects of evidence are considered all prerequisites shall be met. |
Evidence for competence in this unit shall be considered holistically. Each Element and associated Performance Criteria shall be demonstrated on at least two occasions in accordance with the "Assessment Guidelines - UET09". Evidence shall also comprise: A representative body of Performance Criteria demonstrated within the timeframes typically expected of the discipline, work function and industrial environment. In particular this shall incorporate evidence that shows a candidate is able to: |
| Implement Occupational Health and Safety workplace procedures and practices including the use of risk control measures as specified in the Performance Criteria and range; and Apply sustainable energy principles and practices as specified in the Performance Criteria and range; and Demonstrate an understanding of the essential knowledge and associated skills described in this unit to such an extent that the learner's performance outcome is reported in accordance with the preferred approach; namely a percentile graded result, where required by the regulated environment; and Demonstrate an appropriate level of employability skills; and Conduct work observing the relevant Anti Discrimination legislation, regulations, policies and workplace procedures; and |
| Demonstrated performance across a representative range of contexts from the prescribed items below: |
| | Range of tools/equipment/materials/procedures/workplaces/other variables |
| | Group No | The minimum number of items on which skill is to be demonstrated | Item List |
| | A | Demonstrate at least three (3) switching programs that between them encompass the following: | A transformer with a HV winding and fixed tap A transformer with a HV winding and on-load tap changer HV busbars HV isolators HV switchgear (applicable to enterprise equipment) Phasing and phase rotation Commissioning an item of HV plant A planned interruption to a HV customer/s Installation of a mobile generators (if applicable to enterprise equipment) Placing distribution feeders in parallel where special considerations are required to cope with capacitors, phase shifts between different bulk supply systems, sensitive earth fault protection, single phase switching. |
| | B | Prepare switching instructions to isolate, test and earth all of the following | All enterprise transformer types All enterprise busbar types All enterprise feeder types All enterprise circuit breakers, isolators or switches |
| | C | Prepare, write and check switching sheets to do all of the following: | Manage load Manage voltage Minimise losses Maximise network reliability |
| | D | Do all of the following: | Check all above types of switching instructions Coordinate all above types of switching instructions Calculation of plant loading |
| | E | At least one occasion | Dealing with an unplanned event by drawing on essential knowledge and associated skills to provide appropriate solutions incorporated in the holistic assessment with the above listed items. |
Context of and specific resources for assessment | 9.3) This unit should be assessed as it relates to normal work practice using procedures, information and resources typical of a workplace. This should include: OHS policy and work procedures and instructions. Suitable work environment, facilities, equipment and materials to undertake actual the preparation of HV Distribution and Sub transmission Switching programs. Note: Access will be needed to: relevant protection, control, metering, and alarm equipment, network drawings, computerised electrical plant control and monitoring facilities, operational event data, enterprise operational policies, procedures and work practices and enterprise crisis management procedures. |
| In addition to the resources listed above, in Context of and specific resources for assessment, evidence should show demonstrated competency working in realistic environment and a variety of conditions. |
Method of assessment | 9.4) This Competency Standard Unit shall be assessed by methods given in Volume 1, Part 3 "Assessment Guidelines". Note:
Competent performance with inherent safe working practices is expected in the Transmission, Distribution and Rail Traction Industry. This requires that the specified essential knowledge and associated skills are assessed in a structured environment which is primarily intended for learning/assessment and incorporates all necessary equipment and facilities for learners to develop and demonstrate the essential knowledge and associated skills described in this unit. |
Concurrent assessment and relationship with other units | 9.5) |
For optimisation of training and assessment effort, competence in this unit may be assessed concurrently with units: |
UETTDRSO06B | Develop LV distribution switching programs |
| UETTDRSO08B | Develop and evaluate Transmission switching programs |
