Protection and Supervisory Control Systems
Protection and supervisory control systems are indispensable for ensuring the stable delivery of power system reliability. Advanced IT technologies and sensory devices provide high-speed detection of faults, contribute to the prevention of power outages, and minimize outage duration at the time of a blackout.
Protection Relays (MELPRO)
In order to keep the electricity supply stable, protection relays quickly detect possible faults and faulty sections in the power network. This makes it possible to limit blackout area return power to it in the shortest possible period of time.
Substation Automation System (SAS)
The Substation Automation System (SAS) enhances processing efficiency by maintaining an easy-to-use database of a wide variety of substation information.
Special Protection and Control System
A special control system maintains local voltage at appropriate values under usual conditions, and a special protection system maintains the stability of power systems after severe faults by preventing failure extension.
Digital Protection Relays (MELPRO-D/S Series)
Equipped with a high-performance CPU, providing sophisticated capabilities and ease of coordinated protection.
