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 power frequency, switching and lightning overvoltages. The results are based on an investigation… CONTINUE READING
