To reverse the power flow, line commutated converter based HVDC transmission systems use polarity reversal. Insulation is an integral part of any power system, therefore it is of importance to analyze the performance of insulating material for better reliability and safety. The paper attempts to address the performance of insulation under polarity reversals and effect of these reversals on age/life...
Insulation in electrical equipment is a very crucial aspect while designing any electrical system especially in case of high voltages in any part of a power system. Hence it is crucial to determine the properties and performance of an insulating material. The experiments deal with the measurement of breakdown voltages and determination of ageing of an insulating material under accelerated AC fields...
