result of the comparator circuit voltage levels across all the three phases will be assessed. If any two phases running at then the selector moves the load from the mains to the backup generator or the other source. However, the automatic selector system has provision that the feedback current to the load when powered by other sources does not affect the operation this makes it safe to use and ensures continuity. In addition, about power sources it keeps the synchronized status and does not allow varying or rms fluctuations. imbalances during the transition between the two of them. This anti momentary transition ability is critical in circumstances where constant power is important or a must have by sparing the time of the relevant business functions from having to handle power blacks outs. Implemented as an automatic three-phase selector, the system provides a near-single supply power transfer with limited interruptions of service and maximum efficiency in the sector’s consumptions while promoting the constant operation of the necessary services despite the instabilities in power delivery. It is apparent therefore that this system has this significant function of filling voids between supply fluctuations and demand for consistent reliable and steady electric power in the various areas of application.

or drifting phase, and this is something that we come across in just about any industry, home or office setting. In a three phase supply it is often possible that one or two out of the three phases are not live. Due to this, at one time or the other, some of those electrical appliances will be on in a particular room, while they will be OFF in another room. This is disruptive to a common workflow as most activities will have to change to accommodate the new norm. Further more there’s daily increase in load demand; the challenge that is facing most of the consumers is power failure. Because of this power break lot of havoc is wrought on household gadgets and sometimes even life. The difficulty of power pause rises from single phase faults in a distribution system but power is available in other phases. As it can be noticed, most of the domestic loads are intermittent, and normally have a spanning life smaller than the lifespan of the distributed generation plant, we find that they are connected to a single phase supply and if this fault occurs on any of the phases and the power is available in the other phases we cannot make use of this power. Other considerations One would therefore require to switch from one phase to other and auxiliary supply at any one time there is power failure in the one or the three phases of the power supply.

[1] DESIGN OF AN AUTOMATIC POWER PHASE SELECTOR: The three phase power system for design comes with an auto selection of speed depending on the areas that may require the smooth power supply. Such systems are expected to construct spaces with steady light where it is feasible to shift to the stable potency or to the reserve power source (like a generator) every time the space is not actively used. Note that, unlike the antiquated electromechanical systems that take time and also require additional hardware, microcontroller based systems (as described in the work of Udoha & Of ualagba ) are fast, re-programmable, and dependable. The main components are the power meter for sensing the power consumption with high precision, microcontroller (AT89C51), relays to switch the power and an LCD for status; all these combine to produce an energy effect. This automatic solution has been established to help in cutting down the time that is taken in the causing of the opportune time in the businesses as well as in homes. At the same time, despite the high cost and complexity of digital equipment, high reliability of the equipment and the quality of its protection make these systems quite effective, the use

1.INTRODUCTION As a result of the number of interruptions in developing countries such as India, the solutions being proposed are more concerned with the availability of power for both essential and non-essential loads. Suboptimal generation capacity is a primary issue; power outages frequently occur and affect both the private and public sectors, including industries, banks, hospitals, and many other establishments. These establishments have the critical loads that must continue to be supplied power all the time to optimize operations and avoid unnecessary This VP is a response to the task by introducing the automatic Three-phase selector system which ensures that there is easy and an immediate change over of power between different sources and loads. The automatic selector is programmed to remain on alert for the supply voltage signals that fall below a level which is sufficient to drive the electrical or electronic devices. As a
