Abstract –In this paper we have presented our project which is like an automatic transfer system which consists of modules that options will be given to the user to start his/her generator in petrol as well as gas mode also the module will provide the option to user to operate his/her generator automatically as well as manually.

In this paper we have also discussed the limitations of our panel which we will discuss in the later section.

I.INTRODUCTION
The problem of load shedding is very common in our country and mains absence sometimes 4 hours to 6 hours and sometimes 3 days till the mains light comes. People usually turn their attention for this problem towards generator are very well awareof the problems as they are usually started manually using kick start or self start . The user has to go tostart the generator when main supply is absent and then the user has to with the generator when main supply is absent and when
main supply comes then the user has to go to shut the generator off. It is quite a big headache for the user so that is why the need is felt for a automatic transfer switch that is a panel which will provide the user the facility of UPS i.e.automation of generator
This paper comprises of system overview, limitations, advantages, conclusion, acknowledgement and references.
II. SYSTEM OVERVIEW
Fig 1. Block diagram of overall system
A. Power Switching Board
This module consists of a selector(DPST) switch which is used to switch mains and generator. It consists of 12V relays which will this will enable the load to be shifted between mains and generator depending on the availability of the source. The panel lights are used to display which source is active or not and whether it is switched as auto mode or manual mode.
B. Controller module
This module consists of another sub module which is basically destined for auto operation and is micro controller based. It consists of further main sub modules.
1) Status Board: The status board is used to display the operation that is whether it is petrol or gas and the display of mains or generator supply as well as fault and stand by display.
2) Device Operation Display: This is used as another display as well it has switches acting as sensors tosense mains, generator and engine oil.
3) Load : This sub module is used to shift the load to any source which is available.5) Controller: The controller consists of Atmega32 micro controller and it is operated as sinking rather than sourcing i.e. providing ground from controller.
6) Turn On& Ignition : This module is used as turning on and ignition provision to generator.
7) Gas valve: This board is used to operate gas valve.8) Battery Charger: Battery charger is used to charge
the battery and at the same time it also supply the power to the controller.Charger and battery is used to supply unintrupibble power to controller because we want that the controllermonitor the statys of all the sensors and actuators at infinite time.
C. Final Product
4) Battery:This is used to provide voltages to the module i.e. 12V to supply the voltages to outside of module.There are also modules i.e which are used to turn on/ off the whole module as well as reset micro controller and provide neutral to the load side

III. LIMITATIONS
In this project the limitation is that it can not be selected for petrol because in 1 KVA generators there is only manual choke so that is why we don’t automate the petrol choke but it can beautomated by following a proper assembly of motor so in this sense the petrol choke can be automated and full automation can be provided to the end users .
IV. CONCLUSION
From this project we can draw the conclusion that it will guidethe user to select the option of gas as well as petrol with the condition that the generator power rating should be 1 to 10 KVA and the module will ease the life of user who can operate the generator manually as well as automatically which can be added on further advantages. The module can further be builded based on GSM application
ACKNOWLEDGEMENTWe are thankful to under whom we work in this project along with the university for providing us well equipped labs and weare also thankful to our project supervisor Engr. M.Umair Arif for guiding us in this project and related concepts.
