Commissioning & Testing

  • 11 available

Course summary

Since many of the engineers and technicians who initially installed and commissioned much of the existing network plant have now left the industry, there is a knowledge gap regarding the integrity of these systems and how they were commissioned.

This course will give you the skills and knowledge to fill that gap, in both testing existing protection systems and commissioning new ones.

The course will share best practice from across the industry by taking you through the end-to-end process of commissioning and testing using a series of practical worked examples, from planning, design and procurement through to energising plant, loading and sign-off.

You will benefit from presentation sessions and practical testing exercises including protection testing techniques, primary injection testing, secondary injection testing, CT testing and automatic relay testing. The course covers safety, voltage testing, switch-on, handover, records of test results and future maintenance. This approach will also provide you with a fault-finding methodology that is relevant to both new and existing installations.

Great course, learnt so much in a really short space of time.

Dolores, 10 & 11 May 2023

Good balance of theory & practical which linked together well.

Bradley, 10 & 11 May 2023

The course was very informative and delivered excellently by the trainers.

Bruce, 27 & 28 Sept 2023

Engaging delivery with a good mix of practical and class work. More time individually carrying out practical exercises with wiring diagrams would be beneficial.
