-
Compact, safe, and environmentally friendly -
Eliminate the need for bulky air-insulated designs
2. Power Transformers
-
Step voltage up or down with high efficiency and reliability
3. Disconnectors, Earthing Switches & Busbars
-
Ensure safe isolation and system configuration
4. Current & Voltage Transformers (CTs / VTs)
-
Provide critical inputs for measurement and protection
Core Software & Control Systems
1. Intelligent Electronic Devices (IEDs)
-
Combine protection, monitoring, and control in one device
2. SCADA (Supervisory Control and Data Acquisition)
-
Enables remote monitoring and operation of substations
3. Digital Relays
-
Offer faster, more precise fault detection than traditional electromechanical relays
4. Communication Protocols (IEC 61850, DNP3, Modbus TCP)
-
Allow seamless data sharing between devices and control centers
