Tariff kWh meter s and ordinary meters are both electric energy measuring devices, which are used for metering and billing of electricity consumption, and there are certain differences in extended functions.
Tariff kWh meter s are the same as kWh meters:
1. The accuracy class is mainly 1 class
2. It can measure conventional power parameters such as electricity, voltage, current, power, and frequency
3. Support all kinds of installation methods, Din rail type, wall-mounted type, round meter, etc.
4. The voltage specification and current specification are the same, according to the power supply environment of each country and region
Differences between tariff kWh meter s and kWh meters:
1. The tariff kWh meter has the function of segmented metering, which can set different electricity prices according to different time periods to achieve segmented billing, so that users can more clearly understand the electricity consumption costs in different time periods, so as to better plan their own electricity consumption behavior. Through segmented billing, multiple-tariff kWh meter s can encourage users to use more electricity during low hours to reduce electricity costs, reduce power pressure during peak hours, and improve the utilization rate of power equipment.
Ordinary kWh meters do not have a segmented metering function.
2. The tariff kWh meter has a clock function, and the clock error is required to be ±1S/day in the standard to ensure the accuracy of the period of electricity. In order to maintain the clock, the tariff kWh meter is equipped with a lithium battery to maintain the operation of the time. Ordinary energy meters do not have a clock function
3. In order to meet the needs of the high-end market, the tariff kWh meter will extend more functions, and there is an increase in the max demand, reactive power, power factor, harmonics, etc. in terms of power parameters. In the function, there are load profile, event records, event alarms, remote communication, etc.
4. In terms of line design and structural design, the tariff kWh meter is much more complex than the ordinary meter, and the technical content is much higher.
5. The tariff kWh meter has many functions and complex design, and the product cost is higher than that of ordinary electric energy meter.
6. The installation and use of multi-tariff kWh meter s can guide power users to optimize electricity consumption behavior, cut peaks and fill valleys to maintain the smooth operation of the power grid, reduce energy waste, and achieve the effect of energy conservation and emission reduction.
Compound tariff kWh meter and ordinary energy meter in the function of the difference is large, according to different stages, different markets for power metering control requirements are different, both have the necessity of existence, have their own living space, from the development of the electricity market, energy meter to more functional, intelligent direction development, undertake more important responsibilities.
