Distance relays are widely used as main and back-up protection for transmission lines. Their operation is based on impedance measurement at the relaying point, which can be affected by several factors, including pre-fault line loading and short circuit levels at the line ends. Continues demand for electricity energy leads to increase of the short circuit levels along the network, which itself causes...

Distance relays are widely in use as main and back-up protective devices for transmission lines. Their operation is based on impedance measurement at the relaying point, which can be affected by several factors. Continued demand for electricity energy leads to increase in the short circuit levels along the network, which itself causes new problems. One of the proposed solutions for this problem is...
