SCADA Transducer

[bejoyengineer]

In SCADA, the analog output value of a transducer for a tap changing indication gave me a fluctuated value at the output of the transducer. The more we increase the taps of the transformer.. the more the transducer output value fluctuates and thereby not displaying the actual value in SCADA. What is it that could be the reason and how can I solve this issue. The transducer calibration used is 0-21 tap positions = 0 -1 mA ​

hi there

you would be better off on a controls web site i think this is for mostly electrical installation work

just wondered if you are having an harmonic problem

far as i can go
cheers

if incase it's a harmonic problem,what exactly would be the solution that you would be doing??

hi there

I would look to see if there is anything in the circuit sharing common neutrals etc

Is the transformer earthed if it is needed to be and if there is a conflict between the supply output from the transformer to what ever it feeds

do the transfomer cables run in the same area as power supply etc induced voltages

thats all i can help you with mate

cheers

just thought if it is harmonics filtering
