Aims

To provide an insight into the philosophy and design of network and substation earthing systems, and a comprehensive review of recent developments in the related standards, specifications and earthing arrangements.

Outline Of Syllabus

Standard definitions and terminology. Legislation and industry standards. Earth referencing for electricity supply networks. Earthing in MV and HV networks. Earthing in LV networks. Earth potential rise in MV and HV networks. Touch, step and transferred voltages. Resistance of electrodes and earth system. Earth conductor size and jointing methods. Construction, maintenance and cond. Assessment of earth systems.

Teaching Rationale And Relationship

The Online sessions, PiP Sessions and the Distance Learning material provide core material and guidance for further reading. The Distance Learning material also provides problem solving practice and improves planning skills and on-line and computer competences and gives the students the opportunity to manage their own learning. Besides, the post module assignment develops research skills and the ability to utilise relevant information from different sources.

Alternatives will be offered to students unable to be present-in-person due to the prevailing C-19 circumstances.
Student’s should consult their individual timetable for up-to-date delivery information.

Assessment Rationale And Relationship

The post module assignments are an appropriate way to assess both theoretical knowledge and understanding and problem solving skills under time-constraint as required in industry. They enable a more realistic engineering design problem to be set and will also assess data and information acquisition and evaluation skills.
