Designed for Three-Phase Three-Wire Systems
Our 3P3W Multifunction Energy Meter is made for high-voltage transmission lines, large substations, and industrial systems that use three-phase three-wire power. We are Zhejiang Qunte New Energy Technology Co., Ltd., and we built this meter for these demanding applications. It is designed for 3×100V voltage. It meets DL/T614-2007, DL/T645-2007, and State Grid standards. It measures forward and reverse active and reactive energy, time-of-use energy, four-quadrant reactive energy, apparent energy, fundamental power, harmonic power, and copper and iron loss compensation. A mining customer used this 3P3W Multifunction Energy Meter for their main fans. They said it gave them accurate data and helped them watch equipment performance.
Record Demand and Power Quality
This 3P3W Multifunction Energy Meter records maximum demand and when it happened. This helps users manage their power bills. It measures each phase's voltage, current, power factor, active power, reactive power, apparent power, frequency, and internal temperature. All data can be read through the IR or RS485 ports. It is easy to connect to an energy management system.
Reliable with Full Event Recording
This 3P3W Multifunction Energy Meter records events like missing phase, voltage loss, current loss, total power loss, cover opening, and programming cover opening. It monitors battery voltage and load. The battery lasts over 10 years. Time accuracy is ≤0.5 seconds per day. For power plants, substations, and large factories that need high-accuracy three-phase three-wire metering, this meter is a reliable choice.
