The idea is Smart Grid – a dynamic electrical system where at any moment power flows from an available generating station to consumers and the network architecture gets constantly reconfigured to meet momentary power needs and power availability. The direction
Abstract In areas plagued by contamination related flashovers, it is a challenge to decide when to was the transmission line or substation insulators. An experimental study has been performed to investigate the feasibility of using daylight corona detection as a means
According to a DayCor® User “Each has its advantages and disadvantages yet the multi-spectral method combines the 3 effectively to improve the detection accuracy” A 660KV DC transmission line connects 2 provinces in China Yinchuan and Jiaodong spanning 1335 km,
In a research conducted lately by CEPRI – China Electric Power Research Institute that was presented at the SPIE 2014 conference, the use of Ofil’s DayCor® Superb was analyzed. The purpose of the study was to establish operating principles taking
One of the important tasks of electrical utilities is to maintain the reliability of their transmission lines. Due to the growth in power consumption and transmission lines’ length their routine maintenance is a costly one. Aerial inspection is an efficient
to learn more – join CITI Ceramic and glass insulators are being substituted by composite insulators due to their low weight, high resistance to pollution and vandalism and for their lower installation costs. Yet their in-service lifetime is shorter due
The Need for Faster & Hi-Quality Telecommunication Many electric utilities install fiber optic cables on their high voltage lines to satisfy their own internal communication needs and to gain additional revenues by leasing excess capacity to telecommunication network providers. Electric
Mar 1, 2010 12:00 PM By Raymond Ferraro, Public Service Enterprise Group; Emilie Dohleman, Public Service Company of New Modeling predicts corona levels based on configuration, hardware and line voltage. (march 2010 | www.TDworld.com )
David Stuart McLennan – SP AusNetAbstract: Transmission line insulator condition monitoring is of increasing interest with the ageing of many transmission lines constructed since the 1950s. Porcelain and toughened glass and more recently polymeric insulators all have characteristic degradation and pollution
B. Pinnangudi and R. S. GorurIntroduction: Corona discharges can be a significant threat to the integrity of nonceramic insulators (NCI) due to the organic nature of the housing material [1]. For transmission class insulators (69 kV and above), corona can
