A system is devised to detect insulation faults in buried power distribution cables. The system uses a clamp-on device known as a “blocker,” placed at some distance from a signal-injection clamp. The blocker uses feedback control to cancel the injected signal current, approximating an open circuit at the blocker location. To ensure stability of the control loop, the blocker includes a compensator whose parameters are chosen based on an initial line impedance phase measurement. Theoretical and experimental results show that the resulting impedance measurements can be correlated with the condition of the cable insulation in the neighborhood of the signal-injection clamp.

Dr. Robert Veillette received the BSEE from Virginia Tech in 1982, MSEE from Clemson University in 1985, and the PhD in EE from the University of Illinois at UrbanaChampaign in 1990. He is currently an associate professor in the Dept. of ECE at the Univ. of Akron with 27 years of academic experiences.
