Hello all,
I have a 138kV potential transformers with two metering secondary windings 0.3WXYZ. I am wondering if there would be a problem saturating the PT's if a connect the signals to the relays as well for overvoltage and undervoltage protection.
Thank you,

Hello all,
I am specifying a voltage and current transformer for metering purposes on a 138kV system operation voltage under ANSI standards. I thought of specifying a 0.3WXYZ (200VA Burden) for the voltage transformer and a 0.3B1.8 (45VA Burden) for the current transformer.
As you might...
Hello all,
I am not really that familiar with distance relays since the type of work I do is not really transmission lines, but the project that I am working on we need to add a 1/2 km 138kV transmission line that is going to feed a new substation. Originally, I was thinking on protecting this...
Hey guys, I am new to the forum so this is my first post with a question.
I am working in an industrial project where we are designing the substation, we are receiving from the utility company 115kV and we are stepping down to 13.8kV with a 18/24/30MVA transformer to a medium voltage...
