ABB REA101-AAA ARC PROTECTION

Circuit-breaker failure protection The circuit-breaker failure protection is implemented by delaying either the HSO2 output or the TRIP3 output, or both, if required. Note that if both outputs are used, the delay time of both outputs is the same, but the pickup time of the electromechanical output relay (5...15 ms) must be added to the TRIP3 relay. The selected delay time, 100 ms or 150 ms, starts running, once the HSO1 output is activated. The delayed tripping does not take place if the overcurrent signal disappears before the specified time delay has elapsed. Fiber-optic link communication The REA 101 module contains two communication link terminals: Optolink 1 and Optolink 

2. The purpose of the communication links is to send and receive ON/OFF type 6 1MRS756449 B messages between the main modules over a signal transfer fiber. One of the following selectable messages, LIGHT, OVERCURRENT or TRIP, can be transferred over a distance of max. 40 m, when plastic fiber cables (to be used with type REA101-AAA or REA101-CAA) or up to 2 km, when glass fiber cables (to be used with type REA101-AAAG) are used. Self-supervision The built-in self-supervision system of the REA 101 module continuously monitors the operating voltages, the integrity of the cabling between the main module and the extension modules, and the fiber-optic link connections between the main modules. Any fault or malfunction detected by the self supervision system will be used for alerting the operator. A detected fault will block the module to prevent incorrect operation.

Extension modules Extension module REA 103 

 REA 103 is an extension module to be used together with the main arc fault protection module REA 101. The REA 103 extension module is operating as a light detecting module in the REA arc fault protection system. REA 103 detects light and provides the operator with information about the location of the 2 GUID-D260D3EF-891E-435B-A75E-C61724D0F0FE V1 EN 1MRS756449 B fault. For light detection REA 103 can use two loop-type or radial sensor fibers. The built-in self-supervision system of the REA 103 module continuously monitors the operating voltages of the module and the continuity of the sensor fiber loops. Any fault or malfunction detected will be used for alerting the operator via the REA 101 main module.

Extension module REA 107 

 REA 107 is an extension module to be used together with the main arc fault protection module REA 101. The REA 107 extension module is operating as a light detecting unit in the REA arc fault protection system. REA 107 allows connection of up to eight lens-type sensors. The sensor input specific LED indicators of REA 107 facilitate fault location by guiding the staff to inspect the area of coverage of the sensor(s) that detected the arc. REA 107 is equipped with two alarm contact outputs, which enable the partition of the lens sensors into two groups. 8 The built-in self-supervision system of the REA 107 module continuously monitors the operating voltages of the device. Any fault or malfunction detected will be used for alerting the operator via the REA 101 module. A detected fault will block the device to prevent incorrect operation. The lens-type sensors are especially suitable for retrofit installations by providing a more convenient installation of the sensors compared to the fiber sensor solution.
