Temperature Trip set point of the winding of the big Motor

Dear sir,

If the Temperature Trip set point of the winding of the big Motor is 125 ˚C and the Trip set point of the casing is 80 ˚C, do you think we can make two set points for each one? I mean can we make an alarm set point for the winding e.g. 120 ˚C and the Trip set point is 125 ˚C? or do you think the temperature will rise quickly and we cannot make these two points?

Thank you and I’m waiting for your reply.

RTD-100

2) How big is "big"?

It's type is : SCHORCH 11 KV

3) What is maximum Temperature-Rise over ambient?

Max ambient temperature is : 55 C
 
Learner:
How many RTD's are there?
a) If 3 or more, and output is contact-based, then I suggest 2 of 3 Voting.
b) If 3 or more, but their output is frequency related, also use 2 of 3 voting.
