    boiler level control with honeywell UDC 6300

    dear itsmoked, It is fine.I am ready to share.But unfortuatly,i want a faster solution as I am really want to put it back as the system i have put is a makeshift arrangement which i have taken from my plant.I want to put back my sysytem also.So i promise you that i can put back the result in...

    boiler level control with honeywell UDC 6300

    Dear Dan, Thanks for your reply.It was wonderful.I am not clear with point 4 of ur note ( ratio and bias settings).Is it possible to throw more light on that? Your ranges of 0 to 28 for feed water flow and steam flow seem problematic. ( i have defined this as the engineering units low and hi...

    boiler level control with honeywell UDC 6300

    Thanks for your response. Yes.This is the control strategy.The diag u have given is for the UDC 3500 the present version.But the logics are same except that it is having passwords.I checked that.But not much of help from that site. In UDC 6300 the sq rt has been given in the loop1 and loop2 also...

    boiler level control with honeywell UDC 6300

    Dear Danw2, I need the UDC6300 confiuration for boler drum level control.It is a big story.The original configuration done by the commissining engineer was not correct and he did not connected external hardware properly and he had connected both steam and fee water flow in one circuit and...

    11kv motor vs 3.3 kv motor in a 33 kv system

    ok.waross and scooty uk,thanks.This is basically for a a 1200 kw motor.The supply will be better at 33kv.the idea will be hook up at the 11 kv bus in case of 11 kv motor ( the bus is supplied from a 33/11 kv tx)and put an additional transformer of 11/3.3 kv in case of 3.3 kv. soft start starting...

    11kv motor vs 3.3 kv motor in a 33 kv system

    hi all, I would like to know your views on this subjcet which will be a better option with the incomming supply to the plant is 33 kv moderately stable voltage thanks in advance 7465

    DC motor commissioning problem

    Thanks Mr.gunar to give a valuble feedback.I will do the experiment.ow this motor being run is both constant torque and constant power,it should have two field current values as I have given the other motor name plate.One is in constant torque mode ( which will have a higher field current value)...

    DC motor commissioning problem

    dear edison,ok.i got it.I measured the value at the motor terminals.Unless the feield regulating resistance were given inside the motor,which I don th ave the idea.But what is the knee point so that I can find with the little experiment the field current.From your explanation i can make out you...

    DC motor commissioning problem

    Dear edison 123and Gunnar, Thanks for the base speed advise.but I dont think the the direct relationship for the field current is correct.because,the resistance of the field winding is 5.4 ohms.the voltage is 180v.As per yours it is then 180/5.4=33.3A.It can not be.The resistance I measured was...

    DC motor commissioning problem

    Hi, I need urgently your help.Some 3 years ago our DC drive (thyrsitor leonard drive) failed.The basic data of the motor is (95 kw,arm current274A,Field voltage180v SEPA??,380/1200 rpm) I immediately replaced with a abb ACS 800 drive with a new AC motor and run the plant without any problem.Now...

    Inverter for 600KW 60Hz to 50Hz

    i dont understand what you need?first of all most of the inverters are rated for both frequencies. only you have to change the setting. if you are buying one then you can specify first only to the manufactures. iam now talkingabout the incomming frequency. if you are talking of output frequency...

    Generator field saturation

    It will not reduce the out put.THe change in the field excitation is only conncted to the reactive power.There by only the voltage will change if it is running in solo or the power factor will change if it is running in paralell.The active power will not get changed and it is enterly depends on...
