120A with Anti-DC CT;
200A with Ordinary CT.
It is not reasonable.
The power consumption of 120A for 1 hour is about 26.4 kwh, for 1 day is about 633.6 kwh. 10000 kwh ÷ 633.6 = 16.78 days, that means meter's counter takes just 16.78 days to turn a circle. Usually electricity bill is calculate by month, so it is not reasonable and accurate.
Suggestion: integer more than 5 digits.
Anti-DC CT: Insure in a certain range of accuracy, correctly sample alternating current, and DC component.
Correctly measure electricity when tampering happens, which is that add a diode in the circuit to change alternating current to DC current. Without Anti-DC CT, the meter couldn’t measure correctly.
