High Discharge Temperature Setpoint for Reciprocating Compressors
Does anyone know if a rule of thumb exists for calculating what the high discharge temperature shutdown set point should be for a reciprocating compressor based on the theoretical normal operating temperature of the discharge valves? The TC is installed in the discharge manifold.
Electronic Survey Assistance Needed
hi
il will be performing an survey in our plant. I will be survey all the electronic equipment and checking whether it is protected adequatly against lightening,faults etc. need to check whether earthing is properly done.and whether surge arrestors are installed on sensitive equipment. also
earthing
I would like to know what is the cross sectional area required for copper mat used for earthing a normal residential building? i know it will depend on the fault current and soil resistivity. but can i get some ball park figures.?is their any standards for earthing usinng copper mat for residential,
Synchronous Condensers
This power plant is considering converting a generator to synchronous condenser operation. If anyone has experience with this, I would like to hear about it: challenges, cost, operational issues, maintenance issues, equipment changes, etc. There are 2 large generators (ST prime mover) on the order o
Air Mover Properties
I have an air mover. This is a unit that uses a small amount of air to drag in a larger amount of air. The problem I have is that the air is going down a small diameter tube. This tube gets momentarily blocked. This really plays with the principle of the airmover and it decides to blow air the oppos

Generator Voltage Drop
Generator CAT3306 - 180kVA - 380V output...when running for hours. Suddenly output voltage drops to 300V, same rpm/Hz drops during 2minutes, then rpm quickly goes up and frequency passing 54 Hz and generator engine goes off. Same symptoms come up after restarting. What do you guys think...\r\nThx fo
No Load Loss Testing
How to check the no load loss of the Alternator?
We do measure the Input power of the Prime Mover coupled to the alternator, but the Losses of the Induction Motor are not considered, Secondly the PF of the Induction motor running at very less load is also unknown?
