MODULE DETAILS

 

Earthing and Lightning / Surge Protection DEEELS610

 

NOMINAL DURATION IN HOURS

60 hours total time commitment

This time commitment includes the structured activities, preparation reading, and attendance at each webinar, completing exercises, practical assessments and proctored assessments.

It is also expected that students spend additional time on readings, personal study, independent research and learning, practicing on remote labs and required software and working on any projects and assignments.

This module covers fundamentals of earthing in electrical systems, national and international standards, earthing and bonding, systems that cannot be earthed, shielding of sensitive communications cables from noise and interference, surge and transient protection, troubleshooting and fixing earthing and surge problems.

MODULE PURPOSE

 

The purpose of the module is for participants to develop a detailed working knowledge of effective earthing, lightning and surge protection associated with industrial applications.

ASSESSMENT STRATEGY

 

METHODS OF ASSESSMENT

Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor's reports, project work, structured assessments, samples and questioning. This will include short answer questions on the knowledge content, the use of remote and virtual labs, and writing tasks to apply the learning to academic tasks.

 

CONDITIONS OF ASSESSMENT

Assessor Requirements:

Assessors must satisfy the assessor requirements in the standards for registered training organisation (RTOs) current at the time of assessment.

 

Assessors must also hold a tertiary qualification in engineering or related field.

 

The RTO must also ensure that trainers and assessors keep their industry knowledge up to date through ongoing professional development.

Assessment Conditions:

 

Questioning techniques should not require language, literacy and numeracy skills beyond those required in this module. The candidate must have access to all tools, equipment, materials and documentation required.

 

The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

 

Assessments may be open book assessment and may be completed off campus. Invigilation software will be used for some assessments to ensure authenticity of work completed.

 

Model answers must be provided for all knowledge-based assessments to ensure reliability of assessment judgements when marking is undertaken by different assessors.
