∙ 12y ago
Following is the Voltage calculation for a 3 Phase Full wave rectifier bridge circuit with 6 diodes:
Vac rms (Ph-Ph input) = 2pi / 3√2 x Vdc (output)
Vac rms (Ph-Ph input) = 0.74 x Vdc (output)
Hope that helps :)

∙ 12y agoPercent ripple = (Vmax - Vmin)/Vmax
Vmax = (30.5)*(20.5)*VRMS
Vmin= 1.5*(20.5)*VRMS

Can a 415volt 3phase motor run on 525 volt 3 phase?
It is not advisable to run lower voltage motor on a higher voltage.
Why do we use 1.73 as multiplication factor to calculate Phase to Neutral voltage?
because 3Phase power - V X I X Cos Phi X Square root of 3 and square root of 3 - 1.73
Why do you use single phase in house wiring?
bcoz we dont require too much voltage when working in home so in home generally 220v is preferred & in industries 3phase connection is used for heavy loads (440v)
What size wire is needed for a 150 foot 350amp 208V 3phase circuit?
A 500 MCM copper conductor will limit the voltage drop to 3% or less when supplying 350 amps for 150 feet on a 208 volt system.
You get high voltage and burn your appliances due to neutral failure?
It would happen in case of 3phase domestic use where consumer side load balancing is not being done and there is loose connection in the neutral wire. Due to the unbalance and poor neutral, the system neutral will be shifted and un balanced voltages will be recorded in all the 3 phases of the house. The phase loaded with much utilities will indicate less voltage and other will have high voltage. Gadgets connected to this phase will be damaged.
Can a 415volt 3phase motor run on 525 volt 3 phase?
It is not advisable to run lower voltage motor on a higher voltage.
What size wire for a 200 amp 3phase service 100 feet away?
This is a voltage drop question. A voltage must be stated to answer this question.
What is the different between 3phase plus N generator coil and motor coil?
Generator coils generate the voltage, motor coils use the generated voltage.
Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
How you calculate voltage drops in a cable knowing resistance or impedance and line current in a 3phase system?
Ohm's Law - V = IR.
When calculating kilowatts from known amps on a 3 phase circuit do you use 415 volts or the 240 line volts in the equation?
You can use either. I assume the 240 volts is the line to neutral voltage, and the 415 is the line to line voltages. They will both give you the correct answer. It is important to note these values are RMS, not 0 - peak voltages, but this may be beyond your question. The equations below are for calculated from RMS values (both voltage and current).If you are using a L-L voltage, P = I*V*sqrt(3)If you are using the L-N voltage, 1-phase power P = I*V (for the power in a single phase, for all three, multiply by 3), or 3phase power P = 3*I*VYou will get the same answer, since the L-N voltage is (1/sqr(3)) times the L-L voltage.
What will be cable rating for 5kva 3phase system?
It depends on the voltage: 208 v 14 amps, 415 v 7 amps, 480 v 6 amps.
How measure 3phase power without wattmeter?
Take the current average of the three lines.Ex.Phase A = 10AmpsPhase B = 9 AmpsPhase C = 11 AmpsAverage = 10AmpsTake the voltage average of the three lines to ground,Phase A = 460VPhase B = 450VPhase C = 470VAverage 460VPower = V*I (Voltage times Current)Since we have a AC circuit,Power = V*I*1.732CommentUnfortunately, the above equation for power only works if you use line voltage; your explanation describes phase voltages. And, of course, it doesn't take power factor into account.
How many amps will a 50KVA 3phase bank carry on 277 - 480 volts?
50 kVA is 16.667 kVA per phase and you divide that by the phase voltage. Current = 16667 / 277 = 60 Amps
How many AMPs does a 7.5HP motor need?
depending on 1phase or 3phase voltage motor , the amphere requirement is found outfor 3phase AC motor use this formula: (HP x 746)/(1.73 x E x Eff x PF)for 1phase AC motor : (HP x 746) / (E x Eff x PF)
