APPARATUS AND METHOD FOR MEASURING LEAKAGE CURRENTS ON PORCELAIN AND GLASS INSULATOR DISC STRINGS |
摘要 |
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. |
