MODULE DETAILS

 

Shielding, EMC/EMI, Noise Reduction and Grounding/Earthing DBESGE605

Nominal duration: 36 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, general principles of electromagnetism, the fundamental concepts of electromagnetic interference/electromagnetic compatibility (EMI/EMC), shielding, grounding, sources of electrical noise, circuit protection and filtering, effective measurement of EM, and EMC management of power supplies.

MODULE PURPOSE

The purpose of the module is for participants to gain the necessary knowledge to identify design issues and prevent or fix common EMC/EMI problems, with focus on grounding/earthing and shielding techniques.

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.
