Interdigital Capacitance Sensor for Cable Insulation Test and Monitoring
- BATTELLE (PACIFIC NW LAB)
A substantial body of work suggests feasibility to measure cable jacket and insulation conditions using various forms of interdigital capacitance (IDC) sensors. The sensors can either be used to manually test local cable conditions or as permanently installed sensors. Eligible cables subject to these measurements do not include shielded cables but the set of candidate cables is expanded from only unjacketed cables by the ability to assess insulation condition through the jacket. Dual gap IDC sensors are confirmed to be able to sense the insulation condition beneath a polymer jacket and, moreover, the IDC is the only known way to assess the insulation condition through the jacket. PNNL has filed a patent for this approach and is exploring commercial partnerships to exploit IDC technology for actionable field measurements.
