Controls for the reclosers range from the original electromechanical systems to digital electronics with metering and SCADA functions. The ratings of reclosers run from 2.4–38 kV for load currents from 10–1200 A and fault currents from 1–16 kA. [7] [8] On a 3-phase circuit, a recloser is more beneficial than three separate fuse cutouts.
Substation integration refers to combining data from the IED's local to a substation so that there is a single point of contact in the substation for all of the I&C data. Power-system automation processes rely on data acquisition; power-system supervision and power-system control all working together in a coordinated automatic fashion.
Most IEDs have a communication port and built-in support for standard communication protocols (DNP3, IEC104 or IEC61850), so they can communicate directly with the SCADA system or a substation programmable logic controller. Alternatively, they can be connected to a substation RTU that acts as a gateway towards the SCADA server.
Analysis software for lightning protection used on a power substation. Power engineering software is a software used to create models, analyze or calculate the design of Power stations, Overhead power lines, Transmission towers, Electrical grids, Grounding and Lightning [clarification needed] systems and others. It is a type of application ...
IEEE Std 1815 was co-sponsored by the Transmission and Distribution Committee and Substations Committee of the IEEE Power & Energy Society, with additional input from the DNP Users Group. In April 2012, the IEEE approved Std 1815-2012 for publication. IEEE Std 1815-2010 has been deprecated. The 2012 version of the standard includes features for ...

A 115 kV to 41.6/12.47 kV 5 MVA 60 Hz substation with circuit switcher, regulators, reclosers and control building at Warren, Minnesota. It shows elements of low-profile construction, with apparatus mounted on individual columns. A substation is a part of an electrical generation, transmission, and distribution system.
IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations.It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1]
