Hi
i need to know if the steel (St 52-3) is suitable to build a duct working at (400 degree C) for the cement factory.
could any one tell me which mechanical proerties affect the thermal ducts design.
any ref.,links, files would be so appreciated.
thanks
hi
i need to know the types of rectifier diodes and rectification methodes suitable for obtaining a dc power of 110kv at 1 amp. suitable for supplying the electrostatic precipitator of cement factory
best regards
hi
i need to know why is the precipitator cable cross section area used in cement factory = 70 sq.mm although its average dc current < 1 amp. Also i need to know why it is generally be Copper and not Aluminum cable.
any information or link will be appreciated
hi
i need to know exactly the specific heat of silicon steel used in building the transformer cores.
is it same as the (iron/steel) specific heat that is ( 452 J/Kg/K )
thank you
i need to know what is the meaning of ( limit output=200VA ) written on the name plate of a potential transfomer of 6600/100 volt ratio, with a rated output of ( 30 VA ) this pt is single phase class=0.5 transformer.
hi
i need to know whats the meaning of class ( 6p ) that i found in the name plate of a potential transformer of two secondary windings ( first coil class is 0.5 ) and the pt is made in China.
where could i find any detailed information about this please
thank you
i built 0.1 ohm power resistor in order to use it in induction furnace start cct.
the current that must pass throught is: 1000 amper for one second.
could any one help me finding an equation that connect the temperature with time for the resistor.
for more details the resistor width is 60 mm ...
Dear friends
i tried to built an electronic control circuit for earth fault protection, so i built a current transformer with the information listed below ( as i know some informations of how to built them ). the current transformer load is 200 ohm resistive, the voltage that i need to deal with...
