Thanks Davidbeach for the inputs. Were just seeking for some inputs/ideas from other experts based on their experience and also because our consultant is also suggesting that high impedance relaying should have a dedicated ct and not to be connected with other protection devices or metering for...
Dear All,
Just want to ask for your technical recommendations on this area.
Just a background, we plan to purchase a new 15kV metalclad switchgear for our substation and our protection group proposed that we should install two bus differential protections. One differential relay is for main...
Hi Slavag,
Thanks for your feedback. We did already discussed with ABB about our concern and they are still on the process of conducting the studies. For the meantime, we just want also to ask feedback from other companies who had already used the ISL. You mentioned that you had installed in a...
Thanks everyone for all your help and feedback. Very much appreciated. We did already a detailed studies for which part of the system the ISL will be installed which is now in series with the TIE CB.
I would just like to ask everyone if you guys used the ISL in series with TIE CB (just assume...
Hi to ALL,
Good day to engineers!
I just wanna ask your valuable technical inputs or experiences about the IS Limiter that we are planning to use as one of the solution to limit the fault current.
We are building a new substation with four (4) parallel transformers (115/13.8kV). The 13.8kV...
