What is the formula to get neutral current in three phase transformer where three phase cureent are given?
Neutral current is the vector sum of the phase currents. You should be able to add up the phase currents from their polar quantities.
How do you calculate 3 phase earth fault loop?
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.
How do you calculate how to split a 7.5Kw load over 3 phases?
A 7.5 kW three phase load will be balanced by the manufacturer. When connected to a three phase source the line current on each phase will be equal.
If you are given that the line to line voltage is 380V how do you calculate the voltage of each of the 3-phase's?
380V ÷ √3 = 219.4
How do you calculate 3 phase kWh from measuring the total phase current current?
In a balanced 3-phase system, if the three loads are star connected, the line current is equal to the load current. If the loads are delta connected, the line current is less than the load current by a factor of 1/sqrt(3).
When will there be any current in phase?
Current is always flowing in the phase due to the continuous voltage application. the current in phase can be used when it is given a - ve terminal or earth the current would complete the circuit.
How do you calculate output power?
power=work/time=fd/t=watt This is how you would figure out your power or wattage. i hope i could be of help to you!
How do you calculate the total input current from a 3-phase power source when the current from each phase is known?
Add them upAnswerThere is no 'total' current in a three-phase system. The current flowing in each line (not 'phase') is considered separately. And you most definitely don't 'add them up'!
How to Calculate three phase watts with unbalanced phase current?
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
How do you calculate the current for single phase water heater?
You check on the ends of the immersion heater elements. The wattage will be stamped on it. The other thing you can do is look at the instruction manual and find the specs. for the tank. Watts = amps x volts. Amps = Watts/240 volts.
What is the formula to get neutral current in three phase transformer where three phase cureent are given?
Neutral current is the vector sum of the phase currents. You should be able to add up the phase currents from their polar quantities.
How do you calculate negative phase sequence current?
4/4+4*4=20 is it correct by any means or not ? No this garbage has got nothing to do with negative phase sequence current in 3 phase electrical systems.
How do you calculate 3 phase earth fault loop?
You can't have a three phase earth fault, you can have a phase to phase or a phase to earth fault. If you want the potential phase to earth fault current it will be your voltage times your impedance. If you want the phase to phase potential fault current then you should just double the above result.
How do you calculate 1 phase kWh from measuring amps on each phase?
Measuring the current in each phase (or do you mean 'line'?) will not give you sufficient information to work out what you are asking for.
How do you calculate primary AC for 3 phase ac input if output load dc current is known?
DC Current divided by 1.225
How do you convert 400 amp of three phase supply into kwh?
By knowing the voltage you could use calculate the wattage. Power equals volts times amps. Divide by 1000 to get kilowatts.
How do you calculate 1 phase kwh from measuring amps?
You can't. Measure the amperes simply tells you what the current is.
