Sensor type high voltage energy meter

Product overview

Sensor-type high-voltage energy meter is a new type of high-voltage energy metering equipment adapted to the development of smart grid, high-voltage voltage sensors, high-voltage current sensors, high-voltage power supply source, energy metering unit, GPRS communication unit for integrated design, direct access to high-voltage lines. It can completely replace the traditional "high-voltage voltage transformer + high-voltage current transformer + secondary conductor + meter" to form a high-voltage electrical energy measurement device, which has obvious advantages in measurement accuracy, reliability, prevention of power theft, energy saving and material saving.

Intellectual property rights

"ZL200510048228.9 A high-voltage signal sampling method that can be adapted to the needs of metering, measurement or protection", "ZL200710014037.X Sensor-type high-voltage electrical energy metering method", and 18 other subsidiary Patented technology.

Product features

1、Measurement is more accurate. The relative error replaces the uncertainty of the traditional high-voltage energy measurement device, and the accuracy is 2 levels higher.

2、Safety performance is greatly improved. Resistant to DC, industrial frequency, frequency doubling, not affected by ferromagnetic resonance, lightning or operational overvoltage performance, no hot spots.

3, its own energy-saving effect is obvious. The total power consumption of each metering point is less than 8W.

4, small size, easy to install and use. Totally enclosed, through the non-contact, dry maintenance-free structure.

5、No external power supply. Micro-power source technology, directly from the high-voltage side of the source, for metering and transmission unit power supply.
