Power failures disrupt businesses and economies, transport and healthcare. Electrical faults can have serious consequences - including fire, costly damage and a risk to life.

​

VPS consultants can respond quickly to carry out detailed incident investigations. They help clients to pinpoint the underlying causes of any failure of protection systems to perform as required and make recommendations for improvements and changes to prevent the problem happening again.

​

We have worked on investigations in the UK and internationally, across all voltage levels. These include wide‑area power failures involving transmission and distribution networks, loss of generation and disruption to traction power supplies.
