Protection Relays by Application
From overcurrent protection or motor to complex distance protection, our protection relay give you the safety and reliability needed to operate with confidence. Add IEC 61850 Ethernet for best-in-class interoperability and communication in MV and HV power networks.
Overcurrent protection can be used for primary protection, or as a backup for phase overcurrent or earth fault protection. Instantaneous, definite time, IDMT, directional or non-directional are types of overcurrent characteristics often used in protection from basic to advanced feeder applications. Available in a range from basic devices, to complex numerical devices with IEC 61850 communication and cybersecurity.

Arc flash protection safeguards both people and equipment from dangerous electrical hazards. These devices detect arcs in low- and medium-voltage equipment and rapidly isolate power to minimise energy release and risk. Our solutions meet industry safety standards to reduce downtime and create a safer workplace.
Our Motor Protection relays are designed for motor applications where efficiency and reliability are essential. From simple or basic protection to advanced Motor Protection applications, they use dedicated functions and communication like IEC 61850 that enable you to manage motors more effectively and save time.
As transformers are high-cost, essential assets in power systems, protection schemes should be designed to detect and clear any abnormal conditions quickly. In our advanced transformer protection and control devices, we use leading techniques such as multiple winding differential, REF and thermal algorithms, and gather service data to help schedule preventive maintenance.
