Cable testing allows you to determine the degree and severity of deterioration in cable insulation. From the data, you can infer the amount of current leakage and thus energy loss. You can repair or replace the cables to save energy. However, it is unlikely operations people will agree to shut down just to lower the electric bill. So, what’s the point?
Correctly trended cable tests (more on that to come) provide warning of impending cable failure. Although timely intervention prevents disaster, operations people typically delay a needed shutdown well past the white-knuckle point. Use the energy savings angle to sweeten the pot for them.
