How do you calculate multiplying factor in 3 phase kwh meter using ct ratio is 600VA 5 class 5.0?

The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.


How do you calculate multiplying factor in 3 phase kwh meter using c.t. ratio is 2505VA 5 class 5.0?

multiplying factor = Line CT Ratio / Meter CT Ratio Usually it is mentioned on Meter that MF = 1 if CT Ratio is 200/5 or MF = 2 if CT Ratio is 400/5. There can be an additional multiplication factor that would be mentioned on the meter.

What is CT ratio?

CT ratio is the ratio of primary (input) current to secondary (output) current. A CT with a listed ratio of 4000:1 would provide 1A of output current, when the primary current was 4000A.

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.

Is it true that a ratio is a rate?

No. It can be but need not be. For example, you might calculate the ratio of today's temperature in Celsius and in Fahrenheit and calculate the ratio. That is not a rate.


How do you calculate multiplying factor from ct ratio?

The CT standard output is 5 amps at the rated input amps. The CT will have a marking like 400:5, 100:5, or similar, where the bigger number is the input current that will cause 5 amps to flow in the CT secondary. Divide the span by 5 to get the multiplier. For instance: CT - 400:5 400 / 5 = 80 So, if you measure, say, 3 amps from the CT, the primary current is: 3 * 80 = 240 A
