PROTECTIVE RELAYING

Engineering and Design for:

1. Transmission, Sub-transmission and Distribution Lines – impedance, differential, over- current protection and automatic reclosing
2. Transformers – differential and over-current protection
3. Autotransformers– differential and over-current protection
4. Capacitor Banks– unbalance (blown fuse detection) and over-current protection
5. Shunt Reactors – over-current protection
6. Buses – differential protection
7. Breakers – breaker failure schemes
8. Generators – complete protection systems
9. Power Line Carrier (Frequency and Equipment selection)
