Will the amount for electricity change if the current transformer is replaced?
There are three current transformers 2000/5. I want to put 1500/5. Consumption of equipment 670 kW, 380V. The energy supplying organization says that it makes no sense to change, because the counter will count a lot more. Are they right?
Why do you want to change current transformers? Want to save? How do you pass the testimony? Does the controller take off itself or do you multiply the numbers from the counter display by the transformation ratio?
Or you don’t understand anything in essence and climb where you don’t need, or you were very misinformed in energy sales.
If you put a TT with a lower transformation ratio, but when transmitting readings you multiply by the previous (larger) coefficient, then naturally you will pay more than you consume. If you multiply by a real coefficient, the final numbers will be the same as now. BUT, provided that for those transformers that are currently installed, the accuracy class meets the requirements of current regulatory documents (in your case it should be 0.5S, if I'm not mistaken).

Naturally, save.
The counter is now multiplied by 400.
Why will the totals remain the same if the transformation ratio changes by 300?
