Abstract

All dielectric self-supporting (ADSS) fiber optic cable is known to have a limited installation lifetime in some environments when installed near high voltage transmission lines. Dry band arcing has been identified as a contributing factor in the short service life for some of these cables. It has been hypothesized that contamination on the jacket of the fiber optic cable will be an indicator of cable installations that will have a short service life. In this work a portable transducer for measuring contamination levels on the jacket of ADSS cable is being designed, constructed and calibrated in a high voltage environment. The transducer will be designed to operate in both wet and dry conditions. It will measure the electrical resistance per meter of contaminated in-service ADSS fiber optic cable. The transducer will be effective in the range 10/sup 5/ to 10/sup 7/ /spl Omega//m. It will be computer controlled thus requiring little intervention by the operator. This research will include laboratory scale tests with ADSS cable and a 365 kV AC power supply.

便携式ADSS表面污染计

全介质自支撑(ADSS)光纤电缆在高压输电线路附近安装时，在某些环境中具有有限的安装寿命。干带电弧已被确定为一些电缆使用寿命短的一个因素。据推测，光纤电缆护套上的污染将是电缆装置使用寿命短的一个指标。在这项工作中，正在设计、制造和校准一种便携式传感器，用于测量高压环境下ADSS电缆外壳上的污染水平。换能器将被设计为在潮湿和干燥条件下工作。它将测量在使用中被污染的ADSS光纤电缆每米的电阻。换能器将在10/sup 5/至10/sup 7/ /spl ω //m范围内有效。它将由计算机控制，因此几乎不需要操作员的干预。这项研究将包括使用ADSS电缆和365千伏交流电源进行实验室规模的测试。
