Substation Automation Systems (SAS)

We manufacture Control & Relay Panels (CRP) for up to 400kV Systems using IEDs from various OEMs including Schneider & Hitachi.

Bay monitoring & control. Comprise various communication protocols IEC104, IEC61850, Modbus, Modbus TCP/ IP etc and retransmits data to HMI & Gateways.

HMI provides graphical Interface of Substation to Operators / users. Facilitates alarms & events management and stores historical trends for analysis.

 Phasor Measurement Unit (PMU) is a vital component of Wide Area Monitoring Systems (WAMS) capable of measuring the voltage magnitude and phase angle at every system 

 bus in the power system, and the current magnitude and phase angle at every branch (lines, transformers and other series elements), simultaneously and continuously. Using Phasor Measurement Units the WAMS can produce synchrophasors, or derived time-synchronized phasor values, to complete the picture of the functioning electricity grid.

 A disturbance recorder, also known as a fault recorder or event recorder, is a device used in electrical power systems to capture and record information about disturbances or events that occur on the power network. It is an essential tool for monitoring and analyzing the behavior of the electrical grid. 

Facilitates collection of data from IED's / DC on IEC61850 protocol and retransmits to LDCs/ ALDC's/ SLDC's on IEC101 & IEC104 protocols.
