Thanks foe explanation...this seems very clear...
I would just like to know how to calculate Idiff pickup for different situations and how does voltage influence on the calculations.
Here are some Example settings, and test situations:
charging current= 400A
Idiff>480A (1.2*400)
CT 1000/1A
Ic=1...
Thanks for response....
It's around 50km of cable, 220kV.
Ic is setting (according manual) ''Is stabilization/ Ic rated. Parameter which should increase stabilization when we lost voltage.
For example, if differential setting is 480A (when voltage is present), what would be the pickup value...
Hi all...
I have found some difficulties understanding charging-current compensation (Ic), in my case when working with line differential protection.
I have a relay with setting Ic=1, and charging current of 400A, and differential setting of 480A.
How this Ic has influence on pickup value of...
