Can someone enlighten me about correction curve with frequency. I have read about correction curve for ambient conditions (P,T,RH) but was wondering if anything exists for Frequency.

Another information I would like to get is regarding the performance test of GT. Do we need to keep the speed to rated speed during test.

Thanks in advance.

 

Can someone please give a reply to this post. Thanks in advance.

 

Would you still like a response on this? This is a stale thread and I am not sure if you are still following it.

For a contractual test ..Yes. You need frequency correction curve. If you don't have any, then normally the valid frequency regime for the test has to be defined based on mutual agreement. In practice +/-0.2 Hz is acceptable. Almost similar goes no power factor (PF). Normally correction for various PF is available.
