Abstract

Paper insulated lead covered (PILC) cables provide the backbone of underground power distribution in the United States and other parts of the world. Efficient replacement of aged PILC is a looming challenge for the utility industry. Interdigital dielectrometry sensors that measure the dielectric properties of PILC cable are presented. Such sensors may be used to perform low cost health assessment of excavated cable samples. An overview of the theoretical groundwork is presented along with steady state and transient experimental results.
