Protection of Short Transmission Lines Using Microprocessor-Based Distance Relay [PDF]
, 2004 Distance protection is used for the protection of transmission or sub-transmission lines, usually 33 KV, 66 KV and 132 KV lines. A distance relay measures the distance between the relay location and the point of fault in terms of impedance, reactance ...

Energy Conversion and Economics, EarlyView.Abstract An effective method for detecting cyberattacks is essential to the security of smart grids (SGs). In SGs, data from both cyber and physical domains can support attack detection. However, existing works insufficiently consider the heterogeneity, high dimensionality, and cross‐domain correlations of multi‐source data, affecting model ...
