SEL-547
Distributed Generator Interconnection Relay
SEL recommends selecting the SEL-751 Feeder Protection Relay or the SEL-849 Motor Management Relay in place of the SEL-547.
The SEL-751 provides complete feeder protection—including over-/undervoltage, over-/underfrequency, and rate-of-change of frequency—to detect power system problems and separate the local supply from the utility. It is available with a color touchscreen display for simplified operation and supervision.
The SEL-849 protects low- or medium-voltage three-phase induction and variable-frequency drive-fed motors. It detects power system problems and separates the load from the utility using over-/undervoltage and over-/underfrequency elements.
SEL will continue to support and warranty the SEL-547.
