The CHANCE® DC hi-pot adapter has proven to be a very valuable tool for locating faulted cables in an underground loop. It is a simple, reliable tool that adds capability to the lineman’s existing CHANCE 5/16kV or 16kV phasing sets, allowing immediate cable testing during storms and new construction. The compact size and low cost, compared to other available diagnostic cable testers, allows for multiple trucks to do cable testing without long outages while waiting for more expensive and complicated equipment to arrive on the job site.
The CHANCE® Drivecast™ screw displacement pile underwent three installations in the northeast, each achieving significantly positive test results.
As a power utility company, it is critical to understand the benefits and challenges when it comes to substation communications IP migration. There can be major benefits when migrating from TDM to packet networks.
