	During power swing how Distance protection relay will see and what changes will appear in voltage and current at distance relay protection.

	I suggest that you get a copy of GE's Art & Science of Protective Relaying, there's 16 pages on distance relays and how they work. Google and you will find it for free. __________________ “Tell me and I forget. Teach me and I remember. Involve me and I learn.” Ben Franklin.

	This guy is installing a power swing of his own...with red ropes ...I think he needs a distance protection relay... __________________ common knowledge...less common than common sense

	POWER SWING: ...Depending on the severity of the disturbance and the actions of power system controls, the system may remain stable and return to a new equilibrium state experiencing what is referred to as a stable power swing. Severe system disturbances, on the other hand, could cause large separation of generator rotor angles, large swings of power flows, large fluctuations of voltages and currents, and eventual loss of synchronism between groups of generators or between neighboring utility systems.... Power System returned normal state at last without blackout in this sample. __________________ Either exist as you are or be as you look. Rumi
