Cables for Power Systems: Part One

This course is designed to give you a concise yet comprehensive overview of all the main aspects of power cable engineering, from initial design and specification to ongoing asset management.

The aim of the course is to deliver a thorough initial grounding in power cables, joints and terminations, including current best practice and standard operational procedures. The course will assess what is currently available in the cables market, including the latest cable technology, as well as the issues surrounding cable installation and testing.

A highly experienced team of speakers has been selected for their cables experience and expertise, and they will be available throughout the course for you to discuss your cable projects and problems.

By attending the course, you will gain an understanding of:

  • Legislative and safety requirements
  • The role of protection in network design
  • Components of protection systems
  • Relay types and principles of operation
  • Grading principles
  • Basic fault calculations
  • Principles of LV and HV network protection
  • LV electronic relay principles and settings

Day one

Basic Cable Design & Types

  • Definition of a cable
  • LV, MV and HV
  • Protective multiple earthing

Materials & Manufacture

  • How power cables are made, what materials are used and why
  • Processes used in the manufacture of power cables
  • Important characteristics of cable insulation, especially for higher voltage cables

Cable Ratings

  • Current rating reference documents
  • Current rating of cables
  • Temperature rating of cables
  • Rating factors

Day two

Joints & Terminations

  • How power cables are joined together and connected to equipment
  • Role and importance of joints and terminations in power cable networks
  • Various types of accessories in use by UK utilities and industry

Cable Installation

  • Routes-excavation techniques
  • Cable laying, survey, contractor, costs

Standards & Specifications

  • Rules for design and performance of power cables and their accessories
  • Understanding of the various types of cable and accessory standards, what they are for, who makes and controls them, and what are their benefits and limitations

Fault Location

  • Typical fault causes and symptoms
  • Effects and implications

Fault Analysis

  • Best Practice to minimise cable and accessory service failures
  • Understanding why cables and accessories may fail in service, and what can be done to maximise their reliability

Programme may be subject to amendment

This course is designed for engineers and technicians in roles which require an understanding of the principles of power system protection, as well as those working specifically in protection disciplines. It will be of benefit to people working in commissioning, testing, operational and maintenance roles.
As it provides a sound underpinning knowledge it will also be beneficial to the development of new engineers, managers and supervisors and people working in Network Design and Asset Management roles.
The follow-on course, Power Systems Protection: Part Two, is designed for a more specialised audience and takes delegates through protection theory, practice and fault calculations at a level that involves complex numbers.

Recent delegates who have attended this course include:

  • Authorised Electrical Engineers
  • Asset Managers
  • Commissioning Engineers
  • Design Engineers
  • Electrical Engineers
  • Electrical Maintenance Planners
  • Electrification & Plant Engineers
  • Graduate Engineers
  • High Voltage Engineers
  • HV Project Engineers
  • I&E Technicians
  • I&E Engineers / Supervisors
  • Power & Distribution Engineers
  • Protection and Commissioning Technicians
  • Senior Electrical Engineers
  • Service Electricians
  • Utilities Commissioning Team Leaders
  • Wind Farm Managers
