How do controllers and transducers react to varying voltage/frequency
How do controllers and transducers react to varying voltage/frequency
(OP)
Dear collegues,
I'm busy with a project on the respons of our systems to varying grid parameters: voltage and frequency.
There are a lot of controllers in action in the plant, and it would be usefull to know what the respons would be of the transducers and controllers (mostely analogue but also some digital) in degrading grid conditions.
Can anybody tell me what I can expect to happen if the voltage and or frequency changes (raises or drops)?
thanks!
greetings,
Frits

If you really must know specifically, you need to actually look at each one's manual and determine the max and min limits.

There may be situations where you have a ferroresonant stabilizer (constant voltage transformer) supplying a transducer or controller. Frequency variations affect them strongly. A few Hz takes them out of operation. Better remove them if frequency variations are your problem.
