what is amf panel & how it is working..

Answer / pillay

AMF panel is Autamatic Mains Fail panel.

It is not just an electrical panel.A suitably sized gen set is connected to it.The AMF panel has a sensing circuit which can detect a power failure.Now the moment the panel detects a power failure the genset is started automatically. Automatic change over isolators are connected, where the power supply from the mains is changed over to that of the genset.The genset will run and provide the power supply until mains power is available again.The sensing circuit in the AMF panel will detect this and after an adjustable time the automatic changeover isolators will revert back to the mains supply.After a while the genset will switch off on its own.

The AMF panel is connected with certain protections electrically for the genset. It is suppose to operate on its own.The AMF panel is usually connected to important services like security, hospitals and important businesses.

The AMF panel must be tested regularly to ensure it is in working order when the mains fail Otherwise all the money invested in the AMF panel is wasted

what is amf panel & how it is working..

Answer / iar

it is the system to control the standby generator, it stand
for - auto mains failure- and it is working as ATS system
plus it can control the main incomers and make the
necessary synchronizing to restore the power from the main
incomer and after that stop the standby generator

Answer / ganesh

AMF panel is the short form of Auto Man Failure panel. It is normally connected to the generator set to control the generator set function. It can call the generator set if the AMF further connected to the Main Switch Board ( received power from the other source - normally from the local authority ) which equipped with auto transfer switch/automatic changeover contactor. While normal supply serve to main switch board failed, the AMF board will send the power failure signal to generator set. Then the generator set will run and serve the supply to main switch board.

Answer / nisha

Amf panel= automatic mains failure panel .
in this panel 2 i/p , like 1) generator and 2) mains .
suppose mains supply fail to supply load at that time DG start .
in amf panel automatic transfer switch are used to transfer power when main fail .its sense by ats controller , controller give the command ats switch and switch transfer at DG SIDE.
