The HYDROVAR also has an embedded Current Total Harmonic Distortion (THDi) filter that lengthens the overall life of other connected equipment and prevents cables from overheating — without the need for reactor filters. ...
The power inverter inductance of the AC determines the content of current harmonic. Therefore, in order to meet the requirements of grid access, you should guarantee the equivalent inductance value of photo-voltaic power generation system is small. Power inverter is connected to the low-pass filter and isolation transformer. It can filter out the ...
