Dear All,

I was asked by my colleague regarding the working range of an RTD, I mean, upto what temperature can we use a RTD(PT-100) beyond should it be definetly thermocouple ?. Why cant RTD go upto high temperatures

Does it have anything to do with linearity of the platinum, i mean, d

cant we use trip coils' (-) polarity instead of CB 52a ?

trip contacts connects to digital inputs (-)

is it possible?

we can know position all pole of CB if we can measure (-) polarity of trip coils' belong all phase.

your comments please.

Could help me know about COP and EER in Air cooled Chillers and witch range of COP shows us the chiller is better from another type or brands.

Greeting all,

I need some information regarding to surge impedance load and surge impedance characteristic.

I need, what is its usage in transmission line.

Can an Guru or an expert user tell me how work the ICE MAKER mode on CGAM series from Trane air cooled chillers .??????
