Sensor type high voltage energy meter
Sensor-type high-voltage energy meter is actually a direct measurement of high-voltage energy, the use of a variety of weak output current, voltage, non-traditional high-voltage sensors, instead of the traditional electromagnetic current, voltage transformers, as a high-voltage current, voltage conversion equipment
Detail
High-voltage electrical energy overall calibration device
High-voltage electrical energy overall verification device for high-voltage electrical energy measurement and traceability, high-voltage energy meters and traditional measurement devices can be directly measured the error, using high-voltage electrical energy overall verification, measurement method (invention patent No. 200510012796.3).
Run-through electronic energy meters
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.
LJZN1-10
The current transformer principle is based on the principle of electromagnetic induction. The current transformer is composed of a closed core and windings. Its primary winding turns are few, strung in the line of the current to be measured, so it is often all the current flow through the line, the secondary winding turns are more, connected in series in the measuring instrument and protection circuit, the current transformer in the work
