Electrical Power Protection Relays :

Numerical Protection Relays :

1. These are 'Aditya Series' Numerical Relays, which are based on DSP technology. Various protection functions are incorporated in that such as Over Current, Under Current, LBB, Trip circuit, etc.
2. General Protection Relays :
These are meant for 3 phase High-Voltage application for use by public utilities & HT Consumers. These micro-controller based devices are designed with a very simple front-panel control.
3. Traction Protection Relays :
This covers specialised protection relays for 25KV AC Traction protection for Railways. Most of these are sophisticated relays based on Numerical technology.
4. RMU Protection Relay: Numerical Self-Powered RMU Protection Relay and Earth Fault & Short Circuit Indicator
5. Auxiliary Protection Relays :
Auxiliary relays covers electro-mechanical relays used for 'Master Trip' or contact multiplying applications.
