generator current phases unbalance

After changing TCPA Card we found some diagnostic alarms like (tcpa failure #09) comeing =1 & reset =0. after that we found that there is a difference between Generator current phases (DCUR-A=16254, DCUR-B=16476, DCUR-C=14356)

Are this problem due to changing TCPA card? Or Due to another reason?

GSA... some detail please:

1) What are corresponding phase-phase voltages?

2) What are corresponding phase-neutral voltages?

3) What are corresponding power and pf measurements?

4) What is the load? Power Electronics like rectification modules?
