Section 2 ARC600 overview2.1 OverviewWireless Controller ARC600 is a compact, solution based device for remotecontrolling and monitoring of secondary substations, such as network disconnectors,load break switches and ring main units (RMU) in distribution networks. It enables theSCADA system to wirelessly monitor and control the field devices over the publiccommunication infrastructure (cellular network). Wireless Controller ARC600utilizes the built-in wireless communication features for reliable and secure end-to-end communication providing remote monitoring and control of three switchingdevices and can be expanded as required by using external I/O expansion modules.The use of Wireless Controller ARC600 in distribution networks improves the qualityof power distribution and reduces the outage time in the affected areas. Areas directlyadjacent to these affected areas show reduced outages and overall effects. This alsoreduces the capital expenditures in the distribution network by allowing integration oflegacy devices and contributes to more direct cost savings by facilitating preventativemaintenance. The operational expenditure can be reduced by lowering the SystemAverage Interruption Duration Index (SAIDI) and System Average InterruptionFrequency Index (SAIFI), resulting in lower penalties for undelivered energy.Wireless Controller ARC600 is also ideally suited to be retrofitted to existingapplications thus enabling the remote control of these devices and further extendingthe life cycle of the switching devices itself.Typically, the IEC-104 protocol is utilized for communication to the SCADA systembut for the existing installations with a IEC-101 line or modem, Wireless ControllerARC600 supports also IEC-101 communication (including dial-up) to the SCADAsystem.GUID-533791DB-D17E-49EA-B2AB-8E13618BF244 V1 ENFigure 1: Communication system overview with Wireless Controller ARC600and ring main unit1MRS758459 C Section 2ARC600 overviewARC600 9User Manual
