SAFE ELECTRICAL ISOLATION COURSE

COURSE 420: 1 DAY: Max 8 Candidates

This course is designed to provide real evidence that personnel can safely carry out electrical and mechanical isolations. Repeating the course at regular intervals ensures that personnel retain the essential knowledge and continue to use best practices. For companies that prefer the course on-site, site-specific company documentation and procedures can be incorporated into the course, The course also explores the very different issues associated with the dangers of moving machinery and the dangers of electricity.

PARTICIPANTS

The course is aimed at electrical engineering / electrical maintenance personnel who need to perform, supervise or check electrical and mechanical isolations.

COURSE PRESENTATION

Each candidate is given a series of demonstration training rigs on which to practice electrical and mechanical isolations. These simulate the most common scenarios that are likely to be encountered in industrial situations. Comprehensive course notes are provided.

COURSE OBJECTIVES

On completion of the course, participants will be able to:

Successful completion of the course leads to the award of the Technical Training Solutions competence certificate 420: Safe Electrical Isolation.

What do candidates on the Safe Electrical Isolation course actually do?

In order to ensure that the candidates really understand the legal requirements, they spend the first part of the course refreshing their understanding of the Electricity At Work Regulations and the issues of live working, isolation procedures, testing for dead etc. They are also introduced to typical examples of employer's electrical policies and procedures (Company-specific policies can be introduced into the course at this stage).

The candidates then proceed to apply their knowledge in a demonstrable manner by completing a number of practical equipment isolation exercises. These isolations encompass single phase and three phase isolations on industrial, commercial and domestic systems.

The following is one of the units that are used to check that the candidates are able to isolate a single-phase system properly:

The rigs used are slightly different, requiring the candidates to think carefully about the advantages and disadvantages of panel isolations, local or remote isolation etc.

Candidates on the Electrical Isolation course also have to show that they can create a sensitively thought-out isolation procedure for scenarios where production downtime versus the dangers of moving machinery have to be carefully balanced.

The act of testing for dead is explored, and the various ways in which this could be done is explained. We advocate using properly approved voltage testers and proving units. To ensure that the candidates understand this we use a rig that simulates three three-phase motor terminal boxes wired through three isolators. The candidates have to test for dead at each set of motor terminals and some will test out OK whereas others won't and the candidates have to explain what the reasons for this are.

The voltage testing rig used on the safe electrical isolation course, where candidates use the voltage testers to test for dead on three sets of motor terminals: Some test out OK but some don't and the candidates need to be able to explain why this is.
