Most of current arc suppression coil compensation system works based on the magnitude of post-fault distributed capacitance. This system can not offer compensation before fault, so in power system with large distributed capacitance current, short circuit shock is inevitable. This paper proposes an automatic arc suppression coil compensation technology based on fixed-frequency signal injection, it...
The new generation of current sensors, such as Rogowski coils, have performance characteristics that can improve design and operation of modern power systems. This paper presents novel solutions that integrate protection, control, and metering functions for power transformers and cables by sharing signals from the same Rogowski coils.
Protection of power systems requires a high degree of reliability. Whenever a protection is called upon to operate, it must do so. Failure to do so may result in costly damage to plant, loss of supply to many consumers, and potentially, danger to life. Protection relays are designed in such a way as to ensure reliability of operation. Very often, the main threat to reliable operation is the circuit...
