Superconducting power link for power transmission and fault current limitation
Physica C: Superconductivity, 2001 Superconducting power links (SUPERPOLI) will offer the opportunity for low-loss power transmission of high nominal currents and fault current limitation simultaneously in a single device. This paper presents the status of European SUPERPOLI project where the long term goal is to build a GVA class, 20 kV, three-phased, 200 m long superconducting power ...

Fault classification on transmission line of 10kV rural power grid [PDF]
Proceedings of the 2015 4th International Conference on Sensors, Measurement and Intelligent Materials, 2016 This paper proposes a technique using Discrete Wavelet Transform (DWT) and Back-Propagation Neural Network (BPNN) to identify the fault types on transmission line of 10kv rural power grid. The PSCAD is used to simulate fault signals. The mother wavelet daubechies4 (db4) is employed to decompose high frequency component from these signals.
