Generator and Transformer properties.

Hello,

I'm filling out a Large Generator Interconnection Procedure for NE-ISO and I can seem to find two pieces of data it's asking me for.

1. *Generator AC Resistance.* I'm almost positive that they're asking for the wire (cold) resistance data.

2. *Positive Sequence X/R ratio primary to secondary * for the Transformer. The transformer's test reports provide impedance, IR%, and IX% information for Tap Position 1, 3, and 5. I'm not sure how to use this data to get the answer I need.

I apologize for the basic questions, but this is not my forte. Any guidance/help will be much appreciated.

Best,

They're probably asking for the Impedance (resistor).

Most generators are connected in Wye - and the wye is grounded. It's often grounded with a resistor for many reasons... so it's probably asking for that resistor
