Investigation into a double-circuit line fault using the mutual coupling impedance
This paper investigates a double-circuit line fault with non-selective tripping caused by the parameterization of the relay based on inaccurate/insufficient knowledge of the line impedances. Analysis of the fault is based on the measured line impedances and the simulation/system-based testing using RelaySimTest. An appropriate procedure was adopted and documented to measure the line impedances of double-circuit lines in a minimally invasive manner.
Labour pledge to tackle four key barriers in UK energy transition
I'm all for clarity and would welcome anyone who can enlighten me about what Labour's plans are for the size and scale of this Great British Energy....
