Description
- Get the data of voltage, current, power and power factor through AC sampling.
- Dynamically displaying each parameter value of power distribution, simple and quick parameter setting, and the set parameters will not be lost during power failure.
- Automatically detect the number of smart capacitors and control the smart capacitor casting and cutting according to the reactive power parameters of the power grid.
- It has over-voltage, under-voltage, voltage alarm, under-current, over-temperature, voltage, when the grid parameters exceed the set limits, the controller quickly cut off the capacitor that has been put into the power grid, and block the output to protect the safe operation of capacitors and prolong its service life.
- Adopting voltage, current, power factor, irrelevant and other comprehensive calculation of voltage return difference to participate in the control judgement, is more accurate compensation, to prevent the casting and cutting shock.
- Sampling the above judgement value at multiple points during the action delay time, and judging the reactive power trend according to the value of each point, avoiding the judgement disorder caused by single point sampling of the action point of the conventional controller, and accurately judging the reactive power required to be compensated and the direction of compensation (casting or cutting) in the occasions where the power factor varies a lot.
- With manual/automatic switching function. When it is set to automatic, it can control the input or removal of capacitor according to the voltage, load, power factor and reactive power shortage; when it is set to manual, it can operate the input or removal of capacitor manually, which is convenient for the factory commissioning and fast capacitor input and removal. In manual or automatic state, it can realise the simulation switching.
- Switching principle: cycle switching mode to prolong the service life of capacitors.
