High-End Meter for Substations and Power Plants
Our 3 Phase 4 Wire Multifunction Energy Meter is made for places that need high accuracy. We are Zhejiang Qunte New Energy Technology Co., Ltd., and we built this meter for substations, power plants, and large factories. 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 even copper and iron loss compensation. A State Grid customer used this 3 Phase 4 Wire Multifunction Energy Meter for a substation upgrade. They said the data accuracy and features met their standards for billing.
Track Maximum Demand and Power Quality
This 3 Phase 4 Wire Multifunction Energy Meter records maximum demand for forward active, reverse active, and four-quadrant reactive energy. It also records when the demand happened. This helps users lower their base power bills. It measures each phase's voltage, current, power factor, active power, reactive power, apparent power, frequency, and even internal temperature. This gives a full picture of power quality.
Full Event Logging for Better Safety
This 3 Phase 4 Wire Multifunction Energy Meter records events like missing phase, voltage loss, current loss, total power loss, cover opening, and programming cover opening. It also monitors battery voltage. It has IR and RS485 ports for remote reading and programming. The battery lasts over 10 years. Time accuracy is ≤0.5 seconds per day. For power plants, substations, and large companies that need high-accuracy metering, this meter is a trusted choice.
