VPI-CM is a new paradigm non- intrusive cable condition monitoring method used to detect insulation degradation in insulated cables and associated splice, connector, and EPA in an electrical circuit.
VPI-CM is a solution that will save nuclear power plants significant costs over traditional cable tests for Aging Management.
Most cable aging management processes rely on visual inspection and Insulation Resistance tests.
GLSEQ’s invention is in-circuit VPI- CM, which is a cable insulation degradation detection technology that monitors the voltage and surges in insulated conductor cables to detect presence and changes of transient voltage surges to ascertain the integrity of the cable.
Multiple parameters are measured simultaneously and displayed in formats that quickly describe overall cable quality health.
Cable quality health data is taken in real-time.
If the circuit is three phase, all three phases and neutral are monitored simultaneously and non-intrusively with the flexible current probes.
The system also demonstrates how motor startups are affecting electrical cable system performance.
If the circuit also contains, splices, conductors and electrical penetrations, the VPI-CM could also detect insulation damage in these components.
VPI-CM is non-invasive and non- intrusive. The electrical signals, voltages, and voltage surges are detected with analyzers capable of measuring up to three phase 600 V circuits simultaneously.
If degraded cable is detected, unique trouble shooting techniques are used to isolate the degraded cable insulation sections.
