Transformers

Sorry should have explained, 3 transformers in parallel supplying power to 4 VSD's, if the harmonics/noise have been filtered out by adding capacitors and or tuned out at the VSD's and this was done with the tap changers on auto, what will happen if the tap changers are switch to manual? the...

When carrying out a system analysis During design stage (Variable speed drives connected to 3 transformers in parallel) is it a normal practise to check/measure neutral - Earth harmonics, can this be predicted?

If tap changers are on auto and the harmonics are filtered out, what would happen if the tap changers are switched to manual i.e. harmonics/noise
