Converter transients imposed on HVDC converter transformers

  High voltage direct current (HVDC) line commutated converter (LCC) systems have been in operation for over 50 years. At present there are more than 100 systems in operation transmitting more than 100 000 MW of power. Converter transients, imposed on HVDC converter transformers, can produce voltages and currents which result in equipment failure. The […]

Amorphous core material offers lower losses for distribution transformers

  Traditionally transformer cores have been constructed of grain orientated steel alloys, but a new material which has an amorphous structure is being used increasingly in distribution transformers. The material offers advantages over traditional materials and transformers using the core material are being used in a wide range of applications. Distribution transformers constitute the largest […]
