Morning All,
Seeing as we are all becoming more energy conscious of late, (especially in Africa) we had a suggestion to automatically switch off certain motors (e.g: conveyors)and other electrical devices in our plant if they happen to run without any material for more than a certain amount of time. (Amongst other criteria as well.)
I was wondering if there was a feasible way of quantifying the power saved by doing this, to determine if it was a worthwhile exercise or not?
All our motors are linked to PLC's via simocodes, so % of full scale current readings are readily available and motor ratings are available from the name plates. Is it as simple as calculating run time x kw rating x cost/kWh and using this as an indicator of money saved?
Any suggestions will be most helpful.
Regards,
Shaun.
