Nowadays, in the age of Smart Grids, power systems are getting more complicated in order monitor and avoid system down time. End users /operators require the ability to control everything from big substations to small hangover substations; even to each MV cabinet or recloser located in remote areas such as at a consumer site or along power lines.
So do you meet these requirement within a  reasonable cost especially in existing substations, MV cabinets where installation space is very limited.

Solution with ReSy 104 + PLC

The ReSy 104 remote control communication library is based on the IEC 60870-5-104 protocol.

The remote control system enables communication between the control center and substation via a standard TCP/IP network. You can also use transmission via DSL, SHDSL, GPRS, EDGE, and 3G.

With PLC for Fieldbuses and Ethernet, Phoenix Contact offers a flexible system structure that covers a wide range of application options in a centralized or distributed format. Thanks to a compact design and numerous supported protocols, Phoenix Contact PLC is ideal for applications where compact size and high-quality is required at a competitive price.
