Overview
Wireless Controller ARC600 is a compact, solution based device for remote
controlling and monitoring of secondary substations, such as network disconnectors,
load break switches and ring main units (RMU) in distribution networks. It enables the
SCADA system to wirelessly monitor and control the field devices over the public
communication infrastructure (cellular network). Wireless Controller ARC600
utilizes the built-in wireless communication features for reliable and secure end-to-
end communication providing remote monitoring and control of three switching
devices and can be expanded as required by using external I/O expansion modules.
The use of Wireless Controller ARC600 in distribution networks improves the quality
of power distribution and reduces the outage time in the affected areas. Areas directly
adjacent to these affected areas show reduced outages and overall effects. This also
reduces the capital expenditures in the distribution network by allowing integration of
legacy devices and contributes to more direct cost savings by facilitating preventative
maintenance. The operational expenditure can be reduced by lowering the System
Average Interruption Duration Index (SAIDI) and System Average Interruption
Frequency Index (SAIFI), resulting in lower penalties for undelivered energy.
Wireless Controller ARC600 is also ideally suited to be retrofitted to existing
applications thus enabling the remote control of these devices and further extending
the life cycle of the switching devices itself.
Typically, the IEC-104 protocol is utilized for communication to the SCADA system
but for the existing installations with a IEC-101 line or modem, Wireless Controller
ARC600 supports also IEC-101 communication (including dial-up) to the SCADA
system.
