Description

FA200-3.7G/5.5P-T4 model Unimat variable frequency drive (VFD) getting damage then there may be a voltage spikes issue because according to the thumb rule if the transformer KVA rating is 10 times of KVA rating of VFD, say a 100 KVA transformer for 10 hp VFD, then it is subjected to voltage spikes that can damage it. Line reactors are the best way to compensate for that but most users don't use the reactors for small rating VFDs. If your VFD is large enough compared to your generator then there can be issues with the semi-conductors on the VFD firing correctly.
