Certificate in High Voltage Electrical Systems

This module provides a review of the theory and principles of AC Electrical Theory and Circuits. Learners will cover an introduction to three phase circuits, balanced and unbalanced loads and a basic introduction to power factor correction and fault calculations.

This module provides an overview of the transmission & distribution networks of a typical electrical supply system. Learners are introduced to the main elements of electrical infrastructure and cover the selection and testing of cables used in HV electrical installations. An overview of the electricity supply market DSO/TSO, meter, tariffs is provided. Distributed generation will also be discussed.

This module introduces the learner to the various Health & Safety Requirements for Electrical Personnel working on and planning works on HV Electrical Installations. Safety, Health & Welfare at Work Act is covered where learners explore the importance of the Project Supervisor Design Process (PSDP), Project Supervisor Construction Stage (PSCS), the roles of “Authorised Person” and “Senior Authorised Person” as well as the process of preparing RAMS (Risk Assessment, Method Statements).

This module provides an overview of the design and layout of a typical High Voltage (HV) substation. The key elements of a substation will be reviewed and the common configurations and layout will be covered. Earthing of substations and calculations of step and touch distances will also be covered. Maintenance and safety procedures and the range of technical studies required for the safe deign of a substation will also be reviewed.

This module promotes reflection in relation to the learner’s own learning in line with their personal, professional and/or academic interest/needs. The learner demonstrates evaluation and analysis of their own learning and takes the initiative on this evaluation and demonstration. Learners are supported in the development of competencies in High Voltage Electrical systems by utilising a portfolio approach to capture the application of technical learning to a range of industry tasks. Learners will demonstrate a comprehensive range of specialist HV skills and tools as examples of evidence and complete activities to facilitate an understanding of the HV related processes involved in thinking more critically. This module will have a specific set of activities linked to the technical learning of the following modules in Semester 1: High Voltage Safety Compliance AC Electrical Theory Substation Design & Layout High Voltage Power Grid & Infrastructure.

This module provides an overview of the Qualities Required of Protection, Components of Protective Schemes, Protection Systems, Distance Protection, Unit Protection Schemes, Generator Protection, Transformer Protection, Feeder Protection, System Monitoring and Control, System Security and Emergency Control. Learners are introduced to fundamental requirements of Protective Relaying, Basic Relays, Electromagnetic Attraction Relays, Induction Relays, Relay timing, Important terms, Time P.S.M. curve, Calculation of relay operating time the main elements of protection systems, Basic Relay operation and design, timing, specification. Practical application in setting up and testing of Overcurrent and Earth Fault. An overview of instrumentations transformers, discrimination, protection functions (ANSI Codes) control, Interlocking, and logic will also be discussed.

This module develops the learners¿ knowledge of the various Health & Safety Requirements for
Electrical Personnel working on and planning works on HV Electrical Installations. The learner explores EN 61936 and IS EN 50110, the Safety requirements when working on installations with voltages exceeding 1,000 volts and the steps involved in developing a Safe Switching Plan. Learners explore the particular dangers and risks when working in MV/ HV environments and examine how to develop a safe switching plan and lock out/tag out procedures.

The High Voltage (HV) Switchgear module develops a thorough understanding of switchgear requirements for the HV electrical power system. It includes the design, selection, installation and
testing of switchgear.

The Transformer Theory and Practice module develops a knowledge of the modern theory and practice of transformers. The module provides the learner with knowledge of the types, sizing, characteristics, applications and control of transformers in industrial networks and plant.

This module advances the reflection in relation to the learner’s own learning in line with their personal, professional and/or academic interest/needs in High Voltage Electrical. Learners are supported in advancing competencies in High Voltage Electrical systems by utilising a portfolio approach to capture the application of technical learning to a range of industry tasks. Learners will advance the comprehensive range of specialist HV skills and tools as examples of evidence and complete activities to facilitate an understanding of the HV related processes involved in thinking more critically. This module will have a specific set of activities linked to the technical learning of the following modules in Semester 2. High Voltage Safe Working Systems High Voltage Protection Systems Transformer Theory & Practice High Voltage Switchgear.
