At the heart of Power Survey’s GridHealthTM service is the SVD2000 mobile electric field detection system. Mobile electric field detection is the most sensitive and accurate non-invasive testing method available for locating faults in underground electric distribution systems.  The SVD2000 is a purpose built mobile detector specifically designed to detect the low level electric fields that emanate from the surfaces of structures that have become energized due to an underground distribution system fault. It simultaneously detects voltage on all surfaces in an area: streetlights, manholes, fences, hand-hole covers, roadways, and sidewalks.

A world class team of over 75 physicists, scientists, engineers and technicians embarked on a 2-year development effort to create the technology and concepts comprising the SVD2000. The result is an industry benchmark system that has not been equaled in sensitivity or performance.

The SVD2000 has been certified by an internationally accredited independent laboratory for reliable detection of contact voltage in field operating environments.

Our fleet of SVD2000 systems have successfully serviced dozens of utility clients in over 60 cities across the US, Canada, and Europe.  In total, our SVD systems have tested millions of structures and detected over 80,000 instances of contact voltage, more than any company or group of companies on earth combined.  The SVD2000 is the only certified, proven solution trusted by the world’s leading electric utilities.

Power Survey’s GridHealthTM service has been applied in a variety of electric distribution related projects, including:

  • Street Lighting Asset Maintenance and Valuation
  • Distribution System Assets
  • Distributed System Assets
  • Public & Worker Safety
  • Cable Replacement
