Testing & Commissioning

Our highly skilled electrical engineers can perform testing and commissioning on the most complex electrical systems

Our testing capabilities include switchgear, protection, transformers and more

Health and safety legislation requires that electrical equipment must be periodically inspected and properly maintained. While the frequency of testing varies according to the voltage, as a rule, HV assets should be inspected annually and serviced every five years. Inspecting electrical equipment at regular intervals can detect any degradation in performance and prompt the company to create a plan to replace faulty items before they fail completely.
