automatic bus transfer scheme

automatic bus transfer scheme

automatic bus transfer scheme

I am trying to find IEEE or any other standard (vendor neutral document) which discusses about different type of bus transfer scheme - namely slow transfer scheme, residual voltage transfer scheme etc.

Any information about which IEEE standard or any other standarad discusses about those?

RE: automatic bus transfer scheme

Hi teke.

I don't know if possible found some standard.
You can use manuals of HBT systems ( high-speed bus transfer or high speed motor bus transfer)
1. ABB SUE3000
2. Beckwith M4272

Actually four (4) types of transfers schemes are used
1. Fast transfer.
2. 1-st phase coincidence transfer.
3. Residual voltage transfer.
4. Long time transfer.
Two first points with dynamic synchronization only or possible say fast transfer possible make witout any volatge check, only on CB's position and reserve close source time less than 100-120ms.

Please take in account two options:
1. Make before break transfer, close transtion.
2. Break before make transfer, open transition.

Good Luck.
