Solar Power Inverter Pure Sine Wave

TD series solar power inverter pure sine wave 

   Therefore, in order to accurately measure the circuit voltage, the voltmeter must have a very large resistance, otherwise it cannot be ignored, and the measured value will be inaccurate. Of course, we can also think that it is impossible for any voltmeter to not participate. In the circuit, it is impossible to be absolutely accurate, and the voltage value measured by it will always be a little lower than the real value. (This is because the parallel resistance is always smaller than the resistance in any parallel circuit, so after parallel connection The partial voltage of the circuit must be reduced.

  Of course, another point that must be considered is that the larger the range of the voltmeter, the better, because there is always a deviation in human readings. The larger the range, the greater the absolute deviation of the reading. As long as it is suitable for A voltmeter with a range is fine.

  Voltage transformers can be divided into two types: electromagnetic type and capacitive voltage divider type. When the voltage level is 220kV and below, most of them are electromagnetic type, so the electromagnetic type is introduced.

  There are two types of voltage transformers: single-phase and three-phase, and three-phase voltage transformers generally only have a voltage level below 20kV.
