Product advantages:

1. Collect and dynamically display various parameter values of the power grid. The parameter settings are simple, and the set parameters are not lost when the power is cut off.

2. Check the quantity, type, and other information of low-voltage intelligent capacitors, and control the switching of low-voltage intelligent capacitors according to the reactive power parameters of the power grid.

3. Detect functions such as overvoltage, undervoltage, reverse phase sequence, reverse polarity of current, and capacitor fault alarm. When operating conditions are abnormal, the controller quickly cuts off the capacitors that have been put into operation and locks the output to protect the safe operation of the capacitors and extend their service life.

4. Using comprehensive calculations of voltage, current, power factor, and reactive power, voltage hysteresis is involved in control judgment to make compensation more accurate and prevent switching oscillation.

5. Sampling the above values at multiple points within the action delay time, and judging the reactive power trend flow based on the values of each point, avoids the problem of few sampling points and easy judgment errors in conventional controllers. In situations where the power factor changes greatly, it can accurately determine the required reactive power compensation and compensation direction (input or output).
