What is the maximum THD (Total harmonic Distortion) ie. THD (I) and THD (V) a PLC/Electronics can withstand?
I am asking this because in one PLC based Reverse Osmosis plant we have 75 kw VSD inbuilt in the panel with PLC.
We measured 27% THD(I) and 3 % THD (V).
We have had faults in few electronic components especially capacitors on Boards.
Cheers.
