Automatic Transfer Switch

Automatic transfer Switch, time delay???

EMERGENCY!Dalawang supply sa ATS, isa galing sa utility company, isa galing sa generator para sa emergency power supply. 

In case of any undervoltage, overvoltage, loss of phase, or total power failure, ang generator ay gagana after a PRESET TIME DELAY. 

Then once na nastabilize ang generator voltage, that's the only time na ang UTILITY ACB ay mag-oopen o madidisconnect, at ang GENERATOR ACB ay magcloclose.


NORMAL...When the utiility power returns, the utility ACB will IMMEDIATELY BE CLOSED.

However, in this case, hindi agad-agad magdidisconnect ang generator.

Magkakasabay pa din sila.. parehong aandar ang dalawang ACB and after a preset time delay (after magcool down ang generator), that's the only time that the GENERATOR ACB will be OPENED and disconnected again.
