For the sake of giving a reference to the power supply enterprises to select appropriate mode of operation and feeder switches in the implementation of distribution automation, two modes of DAS, i.e., Automatic Switch based DAS (ASDAS) and Feeder Terminal Unit (FTU) based DAS (FTDAS) are compared. It is pointed out that ASDAS is suitable for distribution in countryside wherever the load density is not high, while FTDAS is suitable for distribution in cities and important industrial area with high load density. A comparison is also performed between load break switches and circuit breakers together with the suggestion on the switch selection. Requirements of pole mounted switches for FA are discussed. Design considerations of circuit breaker based DAS are discussed. A typical design showing the connection of a Feeder Terminal Unit (FTU) with a pole mounted switch is given.
