Partial Discharge Surveys

We deliver solutions to Data Centres in a timely, comprehensive and cost efficient manner.

Our Partial Discharge Surveys

We provide a Partial Discharge Testing Service for some of the leading Data Centres. With over 25 years’ experience working on Medium & High Voltage equipment, our Partial Discharge Testing Service combines our expertise with the latest in technology to offer you a quality and unrivalled service.

Over 85% of disruptive failures in medium voltage (MV) & high voltage (HV) equipment are Partial Discharge related. Once PD activity starts it inevitably leads to failure. Our PD testing service requires no shutdown and is an ideal way to plan maintenance, repair or replacement activities in a cost effective and efficicient manner.

Following the partial discharge survey a comprehensive PD Test report is issued, listing any problems found and corresponding recommendations.

What Is Partial Discharge?

A partial discharge (PD) is an electrical discharge or spark that bridges a small portion of the insulation between two conducting electrodes. PD can occur at any point in the insulation system, where the electric field strength exceeds the breakdown strength of that portion of the insulating material.

Partial Discharge Emissions

Partial Discharges emit energy as:

  • Electromagnetic emissions, in the form of radio waves, light and heat.
  • Acoustic emissions, in the audible and ultrasonic ranges.
  • Ozone and nitrous oxide gases.
