Patent number: 9535105Abstract: An apparatus and method for accurately detecting and monitoring leakage currents on porcelain and glass insulator disc strings is disclosed. The sensor apparatus includes a sensor unit configured to attach to a cap of an insulator disc string. The sensor unit includes a sensor disc configured to surround the cap and a housing connected to the sensor disc. The sensor disc includes a conducting lower disc set, a conducting upper disc set, an insulating disc set sandwiched between the upper and lower conducting disc sets, and a conducting mesh connected to a bottom of the lower disc set. The housing including electronics configured to measure and communicate leakage currents on an insulator disc. Leakage currents on a surface of the insulator disc are intercepted by the sensor disc and transferred to the housing for processing and communication by the electronics.Type: GrantFiled: December 12, 2013Date of Patent: January 3, 2017Assignee: Electric Power Research Institute, Inc.Inventors: Andrew John Phillips, Christiaan Stephan Engelbrecht, J.
