if the neutral and ground of ups voltege are connected together in the source itslef then why the voltege b/w neutral and ground comes positive in some other destination inspite of having earth pit. how can we mimmise this?

2087I want to know about DDCMIS in detail ? please explain it. Also give name of reference books in which it is explained in detail in very simple manner.
3754regarding level tx i would like to know how to select the range of the level transmitter in a closed drum(steam drum or deaerator)?
1 7028there is one orifice plate already installed on 3" line, but my previous engineer(who is not working here) removed that tx, but now i want to take it in to the process, so now what i have to do now? flow fluid is hytherm oil of temp. 260deg & pressure is 3bar.
2 5570hi this is noor i wnt know the procedure and precations errection for PRESSURE AND DP transmitters? how to take impusle line for level and flow?(water and steam) impulse line sizes? and type of material ? plz give me answer / reffer any website ? to me "mail2noor.hyd@gmail.com"
