I don't know if you have ever encountered such a thing, when using the power regulator, you find that the actual displayed voltage is different from the measured voltage?
Why is this so? Today we will talk about this topic and find out the reason for the deviation between the displayed voltage and the measured voltage of the dynamometer.
What is Line Voltage Drop? In technical terms, a line voltage drop is when the charge in the line encounters resistance as it flows, resulting in a voltage drop.
It may not be easy to understand, but the layman's explanation is that there will be some obstacles in the road, which will affect the voltage and may cause the voltage to drop.
After the line voltage drop is generated, it usually means that the voltage measured at the display end of the dynamometer is the voltage at the device side, and the voltage measured at the actual measurement end is the voltage at the end of the line, so there may be a deviation between the two.
Voltage measurement has always been about precision and accuracy.
If there is a problem with the equipment used to measure the voltage itself, whether it is a long time to cause insufficient accuracy, or there are other problems, the voltage value it measures may deviate from the actual value.
Power supply and voltage are simply twins, and a change in either of them will affect the other.
Therefore, when the power supply is unstable, it is likely to cause voltage fluctuations and changes, so that the displayed voltage of the dynamometer is different from the actual measured voltage.
There are many reasons for the instability of the power supply, such as changes in load, disturbance in the power grid, etc.
If the control accuracy of the power regulator, that is, the accuracy of its adjustment, is not accurate enough, then the voltage it displays may be different from the actual measured voltage, and there is an error.
There is also a situation that when the dynamometer is working normally, if it responds slowly or has a small processing range, then the voltage it regulates may not be accurate enough, resulting in deviations.

The external environment in which the power regulator is located, such as too high humidity, too high or too low temperature, etc., may cause the display voltage of the power regulator to deviate from the actual measured voltage.
Electromagnetic interference may interfere with the displayed voltage of the dynamometer and the actual measured voltage, resulting in measurement errors. This interference can be caused by other electrical equipment in the vicinity, lightning activity, harmonics in the power grid, etc.
If you find that there is a discrepancy between the displayed voltage of the power regulator and the actual measured voltage, you may wish to see if it is caused by the above 6 reasons.
If so, you can correct it according to the standard, but if not, please share it in the comment area or communicate with us through private messages.
