In exactly the same way as you do so for a single-phase load. It's the product of the power of the load, expressed in kilowatts, and the during of operation, expressed in hours. (And the symbol of kilowatt hours is 'kW.h', not 'kwh')

Can you use single phase kwh meter for three phase load?

No, a single phase kWh meter is designed to measure the energy consumption of single phase loads only. To measure the energy consumption of a three phase load, you would need a three phase kWh meter specifically designed for that purpose. Using a single phase meter for a three phase load would not provide accurate energy consumption readings.


How do you convert 400 amp of three phase supply into kwh?

To convert amps to kilowatt-hours (kWh) for a three-phase system, you need to know the voltage. The formula for three-phase power is: Power (kW) = sqrt(3) x Voltage (V) x Current (A) x Power Factor. Once you have the kW, you can convert to kWh by multiplying by the number of hours the equipment operates.


How do you calculate 1 phase kwh from measuring amps?

You can't. Measure the amperes simply tells you what the current is.


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 3 phase kWh to amps when 8000 kWh monthly average is used?

It depends on the voltage. Please restate the question and provide the voltage. In general, however, simply divide total power by KV to get KA. Remember the KWH is an integral, so you need to back calculate KW. If the month is a 30 day month, then KW is KWH / 30 / 1440. Then, if the load is star, simply divide by three; if the load is delta, divide by three and multiply by 1.732, the square root of 3. Example: 480 three phase running star. 8000 / 30 / 1440 is 185 amperes. 185 divided by 3 is 62 amperes per phase. For delta, that becomes 107 amperes.


How do you calculate 3 phase motor kWH where voltage are 440 and amps are 11?

To calculate the kWh consumed by a 3-phase motor, you'll need to know both the power factor and operating hours. The formula is: kWh = (√3 x Volts x Amps x Power Factor x Hours) / 1,000. Without the power factor and hours of operation, a precise kWh calculation cannot be provided using just voltage and current.


How do you calculate three phase meter reading in kWh with ct coils?

To calculate three-phase meter reading in kWh with CT coils, you need to first determine the current ratio provided by the CT coils. Multiply the current readings obtained from the CT coils with the current ratio to get the actual current values. Then, multiply the actual current values with the voltage and power factor to get the power in each phase. Finally, sum the power in each phase and multiply by the time in hours to get the kWh reading.


How do you calculate the number of turns that are required for the coils of three phase AC motor?

There is software that can be downloaded to help calculate the number of turns for a three phase motor. There are also diagrams which can be found for the most frequently used calculations.


What are the Effects of unbalance loading on kWh meter?

You are, presumably, talking about an unbalanced three-phase load. The answer is no, because the wattmeter takes unbalanced loads into account.


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 low phase voltage of a three phase four wire system without using voltmeter?

The formula you are looking for is - phase voltage/1.73 = phase to neutral voltage.


How do you work out total cost of 35kwh to cost per kwh?

To calculate the cost per kWh given 35 kWh of usage and the total cost, divide the total cost by the number of kWh. For example, if the total cost is $70 for 35 kWh, the cost per kWh would be $70 / 35 kWh = $2 per kWh.
