Choosing your electric energy meter through your monitoring

Jan 07, 2017

Our company is an electric energy meter manufacturer in China, here I will tell you how to select energy meter.

One critical consideration when searching for a proper energy meter is to determine what you're measuring. Is the monitored load signal-phase, split-phase or three-phase? What voltage/current ranges are going to be monitored?

If you're interested in a energy meter for residential or light commercial applications, then typically a single or split-phase meter would be the best choice. These applications use around 120 to 240 VAC, and draw less current than three-phase applications. Three-phase meter applications include chillers, air-handling units (AHU) and process equipment. 

Three-phase meter provides 1.7 times more power than single-phase power at the same current. Three-phase motors can range up to 480 BAC and can handle current ranges of up to 5,000 Amps. Advanced meters will allow you to configure the voltage in the field using a broadband power supply.
