MYBRAIN20 - MASTER / PHD APPLICATION

For those interested in pursuing a Master’s or PhD in the fields of fault location, protection schemes, or any other area of power systems, feel free to PM me personally. We can provide training in Matlab/ATPDraw. 🙂

The deadline to apply for MyBrain20 is August 21, 2024.


Basic Components Of A Protection System

There are several basic components of a protection system as listed below:


CT (current transformer) 

  • Convert the primary current to secondary current and transmit the secondary current to protective relay.

VT (voltage transformer)

  • Convert the primary voltage to secondary voltage and transmit the secondary voltage to protective relay.

Protective relay 

  • Detect and locate the fault and send a trip signal to the circuit breaker.
  • When a fault occurred, the relay will operate by closing the relay contact to complete the trip circuit.

Battery / DC system

  • To supply the power for the relay and also to the trip circuit.

Trip coil

  • As the trip coil of the circuit breaker energized, the CB operating mechanism actuated and will make the CB to open and isolate the fault.
