About the 565-5-5-O-A-E
Relay model 565-5-5-O-A-E is one of the Digital Feeder Management units produced by General Electric Multilin and is primarily used for protecting three-phase feeders. Not only does it protect the feeders and associated equipment, but it can also help prevent any type of personal injury. Continuous and reliable power will be sent to the distribution network to ensure that the feeder protection relay is protecting personnel using the model as well as the network it is being used on. The minimum requirements for the relay are ground current and voltage network monitoring and phase current monitoring which will provide indications of potential faults.
The system status of the 565-5-5-O-A-E relay will be displayed at all times by the LED indicators. If more information is required or wanted the display screen will have full information is requested from the keypad on the device. The screen on this relay can display what has caused a potential alarm or trip.
There are terminals located on the back of the 565-5-5-O-A-E device. Terminals one through eight of this model can accept external switch inputs. These switches are also considered user-configurable and can be set to whatever setting the user requires. The terminals will also prevent certain types of feeder breaker trips and can also introduce a time-delayed alarm if required as well.
All of the above information can be found in the GE 1601-0017 E2.73 565/575 Feeder Management Relay Instruction Manual which has information regarding the Display and Keyboard, Actual Values Mode, Relay Testing, and more.
