Our Products



Control and Relay Panel with Substation Automation System (SAS)


We, Prasiddham Enterprises offer fully engineered Control & Relay Panels (CRPs) used for the protection of electrical networks ranging from 11kV to 500kV. Our state-of-the-art engineering tools are efficient to undertake coordination drawings & cable schedules for the entire substation with ease. We are open to use all internationally accepted IEDs in our CRP solutions.


RCS-9700C - Bay Control Unit (BCU)
This BCU series serves as the monitoring control unit of our SAS. The device is based on modular design,with 32-bit

CPU,multi-tasking operating system, a wide range of IO variations including 14 big high accuracy A/D converters with quantity measurement up to 15th harmonic component. Besides basic electrical measurement, also energy, power and power factor calculations are performed. BCUs are time synchronized via the LAN and adopted time tagging resolution is 1 ms. Interlocking functions, logic control and sync-check functions are based on IEC 61131-3 compliant tools. The hardware is designed for a wide range of ambient conditions with enhanced EMC immunity performance.

Our Substation Interrogation and Monitoring System (SIMS) is a fully integrated and standardized system that can connect any world brand recognized protection relay for the purpose of monitoring and data respectively fault analysis interrogation. All communication is based on the recognized IEC 60870-5-103 protocol. The HMI runs on an industrial PC and provides a systematic, graphical and hierarchical structure from substation level to feeder, bay and device level without limitations. In addition, all kinds of documents such as operation manuals, maintenance manuals, layout drawings, wiring diagrams, device pictures, etc are available online for fast maintenance and troubleshooting at every substation.
