How to Choose a Three Phase Meter？
Three-phase electricity meter refers to the electric energy meter used to measure the load consumption of some large-scale electrical equipment, and is often used in some factories, shopping malls, apartments, and other places. However, there are many brands of three-phase electricity meters on the market, there are also many dealers, and the quality is also uneven. So for enterprises with electricity meter procurement needs, how to choose the model? The following editor will give you some advice, I hope it can bring some help.
Load Power | Main Load Electrical appliances | Application areas | Accuracy Requirements | Meter type | Function requirement | Function Description |
<30kw | Electric lights, low-power air conditioners, electric heating equipment | Storefront, workshop | 1.0 | Three-phase active energy meter | Active energy metering | The reactive power loss is small, and a simple active energy meter can be used |
30-60 kw | Electric lights, electric heating equipment | Storefront, workshop | 1.0 | Three-phase active energy meter | Active energy metering | No reactive power loss, and a simple active energy meter can be used |
30-60 kw | Electric lights, low-power air conditioners, electric heating equipment | Storefront, workshop, | 1.0 | Three-phase active energy meter; Three-phase active and reactive combined energy meter | Active and reactive power metering, reactive power is included in forward power | The overall power is not large, you can choose an active energy meter or a combined active and reactive energy meter |
30-60kw | Air conditioners, electric motors, lathes | Industrial workshop, | 1.0 | Three-phase multi-function meter or smart meter | Active and reactive power metering, multi-function and reactive power are counted into the forward power | Because of the impact of high-power motor load, it is necessary to use a multi-function electric energy meter, and the measurement chip is highly sensitive. |
60-100KW | Air conditioners, electric motors, | Industrial workshop, | 1.0 | Three-phase multi-function meter or smart meter | Active and reactive power metering, multi-function and reactive power are counted into the forward power | Because the power is very high, it need to choose multi-function energy meter |
>60 KW | Air conditioners, electric motors, lathes | Factory, Industrial workshop, | 0.5S | Three-phase multi-function meter or smart meter | Active and reactive power metering, multi-function and reactive power are counted into the forward power | Due to the large power and complex power waveform, a 0.5S-level multi-function energy meter needs to be selected. |
>100 KW | Any load | Factory, Industrial workshop, | 0.5S | Three-phase multi-function meter or smart meter | Active and reactive power metering, multi-function and reactive power are counted into the forward power | Due to the large power and complex power waveform, a 0.5S-level multi-function energy meter needs to be selected. |
High pressure metering | Any load | Transformer at high voltage side | 0.5S | Three-phase multi-function meter or smart meter | Active and reactive power metering, multi-function and reactive power are counted into the forward power | Due to the large power and complex power waveform, a 0.5S-level multi-function energy meter needs to be selected. |
