27TN protection for a 150MW power generator

thread237-493076

27TN protection for a 150MW power generator

27TN protection for a 150MW power generator

(OP)
Can someone help me to adjust the protection values of the 27TN function in a GE UR G60 relay? I understand that it is the site where the third harmonic voltage data should be measured, from the generator neutral transformer.

RE: 27TN protection for a 150MW power generator

If you register at SELINC.com, you can download the manual for the SEL-300G, which has an extensive procedure for calculations and fine tuning in the field. Further, SEL has a paper "Setting the 64G1 and 64G2 Elements in
SEL Generator Protection Relays", that goes into greater detail. Of course, you will have to translate the different settings names and operating principles between the two vendors.

I've never seen this protection work right, but to each his own if you get it to work.
