Network & Substation Services

Complete Diagnostic Solutions – That’s the Doble Difference

High-voltage equipment is exposed to electrical, mechanical and thermal stresses as well as environmental conditions that can act to accelerate the deterioration of insulation, and hence electrical integrity, eventually leading to failure. Performing periodic tests throughout the service life of your infrastructure will keep you up to date on the state of your equipment, and help you to re-define the service-life expectations.

Let Doble Power Services carry out a full suite of on-line surveys to ascertain the health of your substation and plant equipment. We will identify the risks for on-going use of your equipment before they become a serious problem.

Doble Power Services offers the following:

• On-line partial discharge testing
  • RFI survey
  • Partial discharge (UHF)
• Additional on-line tests
  • Infrared
  • Acoustic
  • SF6 leak detection
  • Moisture in oil
  • Earthing
• Surge arrester testing
• GIS commissioning & applied voltage testing
• GIS partial discharge survey

Benefits of substation testing include:

• Identify aging accelerators relating to the site and the application/ utilization of individual key items of plant
• Identify evidence of any abnormalities in the equipment technical condition likely to lead to a shorter life
• Undertake a systematic aging evaluation comparing each key unit to normal life expectancy currently ascribed for the company stock for the group
