Power quality monitoringGWK-10 produced by the manufacturerGeneralized reactive power compensation controllerFunction Introduction
This controller is used for automatic adjustment of capacitor compensation devices in low-voltage distribution systems, and can control the switching of 10 sets of capacitors based on the set comprehensive power factor.
The output circuit adopts a cyclic working mode of first on, first off, and first on. The capacitor can also be switched on or off according to the set sequence.
The instrument can measure and display the comprehensive power factor, active power, reactive power, effective value of voltage fundamental wave, total voltage distortion rate, content of voltage 2-25th harmonic, effective value of current fundamental wave, total effective value of current harmonic, effective value of current 2-25th harmonic in real-time, and can provide advanced indication.
When there is overvoltage, overcurrent, harmonic voltage exceeding the limit, or harmonic current exceeding the limit, all capacitor banks are cut off and an indication of exceeding the limit is given. When there is undercurrent, an indication of exceeding the limit is given, and only the cut off judgment is made without any input action.
