Run-through electronic energy meters

Working Principle

Instead of using the traditional meter tail terminal to introduce the measured current, this series of products has a wire hole reserved for the precision current sensor at the end of the chassis. The measured current wire passes through the wire hole and samples the measured current. The sampled current and voltage are converted into power signals proportional to the measured current through special power metering chips and large-scale integrated circuits to display the consumed power of the measured circuit, and at the same time, it can also output power signals for remote and centralized meter reading, and add special modules to realize the functions of compound rate, prepaid, and active/reactive power metering with the same meter.

Product features

● High metering precision, low power consumption, free of calibration and maintenance.

● Convenient installation, no transformer, no wiring and contact points.

● Reliable operation, anti-theft, no burning phenomenon.

● Convenient for error testing and remote centralized meter reading.

● Wide range of current load, straight error curve, no more than 0.5% error in the whole range, no leakage of power meter.

● Fully enclosed, good waterproof performance, can be used outdoors.

Energy saving effect

● Compared with ordinary electronic energy meters, the penetrating electronic energy meter saves 70% of copper and 80% of iron. 

● Energy-saving effect is remarkable, the current sampling circuit almost no power consumption, compared with the ordinary electronic energy meter, each single-phase meter annual power savings of about 2.8kwh. three-phase meter annual power savings of about 8.4kwh.

● Using through the electronic energy meter can save about 50% of the annual power, thus saving the measurement cost.

● No need to match the transformer, power reading, not only to reduce investment, reduce the secondary circuit, and reduce the artificial measurement error and CT error, loss reduction effect is obvious.
