We have frame-5 gas turbine machine for power generation with GE mark-5 control system. Now we are getting the alarms "BATTERY 125V DC EARTH GROUND."
We checked the floating voltage on the battery charger panel side found 110 V on positive (+ - 0) side and 15V on negative side (- - 0). Now the machine is in shutdown condition still we getting the alarms. can anybody suggest is this alarm related with battery charger circuitry or related with control system or any i/o circuitry and what are the check points have to carry out?
