SEL-547 Distributed Generator Interconnection Relay
Apply low-cost, compact package with essential protection and control elements for distributed generation.

Apply the flexible SEL-547 at the transfer switch site (interconnection point between the utility and the customer) and at each individual generator site. When the SEL-547 at the transfer switch site detects utility supply problems, it separates the customer system from the utility supply. When the SEL-547 at an individual generator site detects a system problem that could adversely affect the generator, it separates the individual generator from the rest of the system. The SEL-547 product flyer figures show examples of the SEL-547 "in action" at the transfer switch site and at an individual generator site. Other applications and scenarios are possible.
