Hi guys,
Currently I am working on two parallel cable, it has phase directional relay both in the end load,.Vamp 230 phase directional.
How can we set direction of protection??
what U/I angle meaning??
I Have experience,under normal condition U/I line 2 is -100 degree and Line 1 is 64 degree, the phasor measurement almost in the same angle. But for angle offset in directional protection is -45 and +45 unles the relay will trip under normal condition..
Can you guys help me to interpret this??
