Thanks Guys for your post.
Also i have noticed that the system/transformer is low impedance grounding using earthing transformer (max current is 2000A)
Here as per the settings, 2720A (0.85% of 3200A) is available. obviously the protection will not operate for earth fault currents since the max...
Hi,
I need explanation for the below.
In one of my project, partial Differential BB is available using Incomer and Buc coupler CTs. Also series resistor is available in the circuit like High impedance circuit but no metrosil. And the settings seems as a overcurrent settings. the protection...
