Can you design a microcontroller program for a three phase automatic generator changeover on main load failure?

This circuitry is already in the market place. It is in the form of an ATS (automatic transfer switch). The controller is pre programmed for sensing and switching. Customer input is limited to setting of the timing of the relays in the transfer switch.

How does AMF panel for generator work?
AMF stand for Auto Mains Failure. Generally a generator/alternator power and normal commercial line switching over is done through it. A normal changeover, if mains fails you have switch the load circuit to generator, and when mains restors, generator supply will be cut off and fed to mains. in AMF this done by contactors and control circuits. if you want to know more......
What are the causes of failure of self excited generator?
there is problem in AVR and magnetic strength.
What is the difference between ATS panel and AMF Panel?
ATS (automatic transfer system panel) it will transfer load from main power to emergency without operation when the power source drop below 80% or normal voltage while AMF (automatic main failure panel) this will substitute as main electricity source and reserve the generator if the main supply fail or down.
Why electric generator drop the load?
Too much load for the generator, the generator began to under speed / overspeed, the governor / part of the generator went into failure, the generator capability was not up to the requirements placed by the system (needing to push out/pull in too many VARs), etc. there are many reasons for a generator to drop a load. Because a load dropped, this does not infer that the generator was the cause either (fault on the system, system instability limits reached, system protection tripped - non-generator related protection).
What is the Difference between uninteruptible power supply and generator?
The UPS uses batteries to supply power when you have a power failure. There are two main types 1) Switched where the voltage is not applied until the power company voltage is removes and 2) continuous where batteries are continually being charged and running an inverter to supply AC. A generator takes several seconds to come to speed after a power failure is detected. Hence a generator is fine for things like lighting and house hold appliances, but not for computers if you value your data. In an optimum system a UPS may be backed up by a generator since the batteries in an UPS typically are not designed to provide backup power for a long period.
What is AMF panel?
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.

What is a fail passive and a fail operational auto pilot system in aircrafts?
Fail-passive Automatic Landing System An automatic landing system is fail-passive if, in the event of a failure, there is no significant out-of-trim condition or deviation of flight path or attitude - but the landing is not completed automatically. NOTE: For a fail-passive automatic landing system the pilot assumes control of the aircraft after a failure. The following are typical arrangements: (1) A monitored automatic pilot in which automatic monitors will provide the necessary failure detection and protection. (2) Two automatic pilots with automatic comparison to provide the necessary failure detection and protection. Fail-operational Automatic Landing System. An automatic landing system is fail-operational if, in the event of a failure, the approach, flare and landing can be completed by the remaining part of the automatic system. NOTE: In the event of a failure, the automatic landing system will operate as a fail-passive system. The following are typical arrangements: (1) Two monitored automatic pilots, one remaining operative after a failure. (2) Three automatic pilots, two remaining operative (to permit comparison and provide necessary failure detection and protection) after a failure.
How can you prevent your data from general power failure?
Battery power. Generator.
What are the signs of transmission failure?
depends is it standard or automatic
What are the causes of failure of self excited generator?
there is problem in AVR and magnetic strength.
What happens at the rated value of the voltage of the generator?
The rated voltage of a generator decreases due to many causes such as armature reaction, overloading of the generator and AVR failure/ weak excitation voltage.
What is an ats panel?
Automatic transfer switch An ATS (Automatic Transfer Switch) is an expensive auxiliary piece of equipment and depending on the standby situation, is not always used. In emergency situations when a power failure occurs certain establishments need instant recovery from no power. Hospitals, town water distribution systems fall into this category. Some of the less priority recovery establishments will use a manual transfer switch. This is where the operator will start the generator and then transfer the utility incoming power to the generator power to feed the load. Then you have the home owner generator that just needs the pull of a handle to start the generator and you just plug in the load. So to answer the question, not all generators need to be connected to an ATS; it depends on the situation the generator is used for.
What cause of low pressure on automatic transmission?
bell end failure
A hospital has a backup generator to power the medical devices in case of a power failure Which of the following is the most likely source of mechanical energy for the generator?
gasoline or diesel fuel
