Abstract :
The need for a distribution current limiting device (DCLD) by the utility industry is addressed. An evaluation was made of what specifications would be acceptable and what DCLD technique would fill the utilities´ needs. Using this survey and a distribution system analysis, a DCLD that could limit a 20 kA fault to 10 kA in a 15 kV circuit was shown to be the primary candidate for further development. The study showed that gate turn-off thyristors (GTOs) are the best technology available that could be developed into a practical DCLD. A recommendation was made to develop a DCLD using GTOs
