How many 16 Amps per phase welding outlet can you install to a 30 KvA rating transformer?
..the questions does not say wether the 30kVA transformer is 3 phase transformer or single phase transformer..but it is implying that a single phase welding load at 16A per phase is to be connect to it, it is assumed then that the transformer is 3 phase transformer..we assume load is rated 240V.. ..though not much details is given about the transformer voltage specs. but if is rated 3 phase 415/240V, the approx full load current per phase is given by 30KVAx1.3912=41.736A.. ..but if the transformer was rated single phase 240V say, the approx full load current FLC=30000/240V gives 125ampers.. ..if you further devide the FLC by the intended load current.. ..Recommended no of welders per for a 3 phase 415V transformer and assuming single welding sets =41.736/16=2.6..so you can connect max two welding sets to this transformer per phase,..max 6 weld sets can connect at an approx load factor of 76%.. ..for the single phase transformer, FLC/16=125/16, gives 7.8 but is also recommended not to connect more than 6 welding sets to such transformer for the same reasons..
What are standard speeds of single phase motors?
Single Phase motorRPM (Revolution Per Minute) depends on Frequency used & the number of poles of motor.So this RPM of single phase motor usually 300 to 3000 depending upon F & P.
Who is the CEO of the NEC corporation?
NEC does not have a CEO per se. However, the President is Nobuhiro Endo.
What is the different single phase unit price and three phase unit price?
If, by 'unit price', you mean the cost per kilowatt hour, then there is normally no difference between the cost of energy supplied whether by single-phase or three-phase supplies.
What is the maximum dose of Demerol per single dose administration?
What is the max dosage per day for Demerol
How does single phase alternator differ form a dc ganerator?
Single phase alters from positive to negative at 50 (50hz) or 60 (60hz) times per minute. While in dc it does not vary but stays at a constant positive phase.
Why three-phase rectifier is preferred upon single-phase rectifier?
The choice of single or three phase depends on the available supply. But a three-phase full wave rectifier provides 6 pulses of DC per cycle, while a single-phase full-wave rectifier provides only two. That makes the output DC easier to smooth.
What is the formula for calculating the full load current of 11 kV generator?
Basically the formula is I = P / V where I = amps, P = power (kV) and V = volts for a single phase 11 kV genset the formula is 11000/400 = 27.5 amps max load. For a 3 PHASE GEN then 11000x0.8/400/3 = 7.3 amps per phase.
What amount of kitchen counter requires a receptacle?
No point on a countertop can be more than 24 inches from a receptacle per NEC 210.52. They have to be GFCI outlets per NEC 210.8.
Is the kva rating of a three phase generator per phase or a total of the three phases example is a 3 phase 75 kva generator 25 kva per phase or 75 per phase?
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
