NettetBecause of outstanding selectivity and short operating time, current differential protection (CDP) is always first option of primary protection for transmission line. Its criterion of internal fault is given, as in (1) I con + I g ⏟ I op ⩾ K I con - I g ⏟ I res where I op and I res are operating current and restraining current, respectively. Nettet7. sep. 2024 · It uses differential protection principle i.e. under normal working conditions the current entering one end of line is equal to that leaving the other end. If fault develops, the balance is disturbed and the difference of incoming and outgoing current flows through the relay coil and trip signal is produced that operates the CB and thus faulty part is …
