1、 Overview

A power transmitter is a device that converts measured power parameters (such as DC current, DC voltage, AC current, AC voltage signal) into DC current, DC voltage, and isolates and outputs analog signals.

2、 Technical parameters (the product complies with the national standard GB/13850-1998)

3、 Dimensions and wiring diagram
4、 Precautions

The transmitter needs to be preheated for 30 minutes before precision measurement can be performed.

2. The wiring of signal input, transmission output, and auxiliary power supply must be correct.

3. To calibrate the instrument, it should be at level 0.1 in order to ensure accurate calibration.

4. The marked and placed potentiometers are used for transmitter calibration, and should not be calibrated without standard instruments or by non professionals.

When the auxiliary power supply is DC, the input signal and the auxiliary power supply cannot be grounded together, otherwise the transmitter will burn out.

1Maintenance of three-phase three wire reactive power transmitter

It is necessary to perform fault detection when we need to maintain a three-phase three wire reactive power transmitter. The testing of three-phase three wire reactive power transmitters generally requires the use of two instruments, namely an oscilloscope and a multimeter.

Oscilloscope is used to test circuit ABAre the two points showing a square wave pattern? If they are not showing a square wave pattern, there may be an error in the signal. This situation is highly likely to be due to issues with the wiring used by these two points in the past. A multimeter is used for testingC、DIs the voltage between two points almost equal? If the voltage difference between these two points is very large, it may beA、BThe balance between the two points has not been adjusted properly.

2Maintenance of three-phase three wire reactive power transmitter

Regular maintenance is a good way to extend the service life of three-phase three wire reactive power transmitters. When maintaining, we need to first conduct a simple inspection of the temperature, humidity, and cleanliness of the surrounding environment of the three-phase three wire reactive power transmitter. The usage environment is very important for three-phase three wire reactive power transmitters.

Next, we need to check whether there are any leaks or corrosion issues with its overall and internal components. If these situations occur, we need to repair them in a timely manner.

If you want to extend the life of a three-phase three wire reactive power transmitter, it is necessary to regularly inspect and maintain it. After inspection, it is necessary to carry out drainage, condensate removal, and blowing of components such as pipelines that are prone to blockage. After completing these cleaning tasks, we also need to apply lubricating oil and professional anti-corrosion agents between its various components. Make the coordination between its various parts more flexible and tacit.
