Answer / mahadev kandagalla

There may be sudden increase in current, due to sudden DEACCELERATION that time drive may trip so my suggestion is that in any VFDS you will get DEACCELERATION time setting so just set it for a proper timing so that drive will not get trip.

I have calculated load for an office building which is 1200 KW as all the load is single phase therefore its 1200 kw single phase. Now i have to design Transformer and Generator for this load Please kindly give me exact answer that how much capacity of Three Phase Transformer and Three Phase Generator is required for this load.
