We are having a Frame-V gas turbine machine using Mark-V control system and now we are facing one problem related to SRV LVDT feed back differential trouble alarm. this alarm is coming and become normal after some seconds. we checked both LVDT feed back, and found that one LVDT feed back is fluctuating between 1.6V TO 2 V. the good one is always showing 2V. also we checked the excitation voltage and tightness of the LVDT core found normal.
Can anybody suggest what will be the possible cause of this voltage drop issue? and is it advisable to check in running condition, even though the Mark-V is taking feed back from the higher value (i.e.,2V)?
