Substation automation, protection and control systems are critical to the electric power system and are widely implemented by electrical utilities due to the significant role they play in improving the overall safety, efficiency and reliability of the power system.
Sigma resources have the capability and expertise to specify, design, configure, implement, pre-commission, commission and support various substation automation, protection and control systems. Sigma’s expertise stems from a solid understanding of power system theory and fundamentals. This knowledge, combined with our extensive project experience in the electrical utility industry, enables us to offer services in a number of areas and with numerous devices including:
- Protection relays
- Automation controllers
- Data concentrators
- Digital meters
- Programmable logic controllers (PLC)
- Operator interfaces or human machine interfaces (HMI)
- Remote terminal units (RTU)
- Dedicated intelligent electronic devices (IED)
