Estimation of Magnetic Fields near to High Temperature Low Sag Conductors

Abstract

High temperature low sag (HTLS) conductors are recently being used worldwide due to several advantages of operating at higher ampacity and continuously at much higher temperature in comparison to conventional ACSR conductors. HTLS conductors are of recent origin, there is a need to study and evaluate many parameters. In the present investigation a simulation model based on IEEE-738 standard is developed for computing various parameters, some of the parameters have been verified experimentally in the laboratory. Magnetic field estimation and measurement is one of the main focus of this work on HTLS conductors. Both simulation and experimental mapping of the magnetic field on various conductors has been conducted to ascertain the levels of magnetic field around a conductor. It is believed that the results presented will be useful in formulating safety guidelines in future.
