CableWISE® is a unique, non-destructive on-line electrical system condition assessment process that enables electric utilities and a wide range of commercial/industrial facilities to evaluate the condition of cable systems, transformers and switchgear. Knowing a cable system's weaknesses enables owners, asset managers and reliability engineers to be proactive in identifying and repairing problems before they cause outages.

History:
CableWISE technology was developed and initially implemented in 1984 on a 138 kV rated cable system owned and operated by Detroit Edison.  Additional research and development ensued over the next several years with a focus on distribution-class cables.  In 1998, an automobile manufacturer located in Detroit was the first commercial customer to take advantage of this technological breakthrough.  The technology can successfully detect the deterioration in cables, splices and terminations on both new and aged cable systems.  This innovative technology is now available to all utilities and industrial customers.  Over 50 million feet of cable systems (predominantly distribution and transmission-class) have been assessed in the field.  The technology is applicable to all cable types (PILC, XLPE, EPR, Rubber, etc.).  Customers, both electric generators and consumers alike, have applied the CableWISE condition assessment program annually in order to improve the reliability of their power delivery systems.  In January of 2007, the CableWISE Group was acquired by UtilX® Corporation to complement its CableCURE® technology and services.

Features:

On-line Expertise:

  • Assessment is performed on-line at system voltage

  • No outages or switching operations are required

  • Non-destructive

  • Non-invasive

  • No over-voltage is applied

  • CableWISE® assessment does not shorten the remaining life of the cable accessories or other equipment

  • Provides "true" assessment of cable system

Rapid:  On-line data acquisition is performed in minutes

Safe:

  • Subject cables are not required to be disconnected from the system

  • Exposure of personnel to energized environments is minimal

Complete:  Assessment results indicate the condition of the cables, cable accessories and connected equipment under normal operating conditions

Benefits:  Selecting CableWISE to assess transmission and distribution cable systems, results in these direct benefits:

  • Eliminate downtime and potential damage to existing cable systems

  • Prioritize capital expenditures by identifying cables for repair, treatment or replacement

  • Increase customer satisfaction by identifying incipient faults before they become outages

  • Assist asset management in justifying increased funding for improved reliability
