Conventional transducers are widely used for high voltage measurement and monitoring purposes. However, these transducers are known to have several drawbacks. This limits their widespread deployment in large numbers especially in high voltage applications such as substation equipment or overhead lines located in rural areas. Hence, a voltage transducer is proposed based on a novel exploitation of...
Voltage uprating is a reliable method for increasing the power transfer capability of an existing overhead line. It is essential to meet the primary air clearance requirements for power frequency, switching and lightning overvoltages while evaluating the suitability to uprate the line to a higher voltage level. In this paper, a method is discussed to establish the necessary clearance envelopes for...
While uprating an overhead line to a higher voltage level, it is often difficult to achieve the required clearance level for the uprated structure. Use of Transmission Line Arresters (TLAs) is an effective technique in controlling overvoltages and thereby, achieving the required clearance margin. In this paper, suitability of this technique in reducing the clearance margin is discussed. A case study...
