how i calculate actual meter reading, when i have main meter 250kw 15/5 ct & connect to 5 sub meter dual secure meter having ct 150/5,100/5,200/5,150/5,150/5, in Kvah
sir my question is- one is a main meter 250 kw having 15/3 ratio. five sub meter is attached with this meter having 150/5,100/5,200/5 150/5,150/5 CT ratio, so i wanna actual meter reading. & how will be find actual unit consumption & how will be debit on them.
Your main meter ratio is 5:1.You should convert the readings shown by the sub meters by multiplying by them by individual CT ratio times the main meter ratio.
The meter multiplier will be the the product of the CT ratio and the PT ratio. Since there is no mention of a potential transformer, I assume there are none. To this end, meter multipliers should be:
Main- 3 (are you sure it is not a 150/5???)
Sub1- 30
Sub2- 20
Sub3- 40 and so on.........................
There may be some differences due to accuracy as well as transformer losses down stream of the main meter.
