The Secret of Current Specification of Watt-hour Meter

Watt-hour meter is an indispensable equipment in home and business places, and current specification is one of the key factors to choose a suitable watt-hour meter. So, what are the specifications of common watt-hour meters at present? Let's reveal the secrets one by one.

1 Common specifications in the market

5(60)A, 5(80)A, 10(60)A and 3*5(80)A (three-phase meters) are all common specifications in the market at present. Different specifications meet different electricity demand, so it is very important to choose the appropriate specifications.

2 Basic current and maximum current

Take 5(80)A as an example, its basic current is 5A, and its maximum current is 80A. The smaller the basic current, the higher the sensitivity of the watt-hour meter and the more accurate the measurement. The maximum current is the maximum current that can be accurately measured by the electric energy meter. When choosing an electric energy meter, you must know the electricity demand of your home and choose the appropriate current specification, so as to ensure the accurate measurement and safe use of the electric energy meter.
