The process can be complex if it involves starting and stopping of source like generator and monitoring of mains It has the capacity to automatically switch power from national grid to generator and vice versa, once there is power failure in any of the two power supplies Abstract: Change over process involves switching electrical load from one power source to another, when the load is powered by two alternative sources (main utility and stand by generator). The motorized change-over switches have snap-on control wire connections. Auxiliary contacts can be snapped on to the sides of the switches and the power terminals can be An automatic change over switch can be entertained to allow smooth and fairly uninterrupted supply of electricity for operation and services that require no discontinuity This concern birthed the design of an automatic transfer switch therefore, the aim of this project is to design and construct an automatic power change-over switch that switches ABSTRACT: In this research, a “3-Phase Automatic Power Change Over switch” has been designed and implemented using three voltage Comparators (LM AH), require frequent switching between power sources The purpose of this document is to give examples and tips on implementing automatic transfer switch solutions based on In this paper, we provide an automatic switching mechanism that transfers the consumer loads to a power source from a generator in the case of power failure in the mains supply. The automatic change-over switch monitors the three phases of the public power supply and initiates the turning on of the generator and changing over of the supply whenever either of the phases of the This research covers the design and construction of a single phase microcontroller-based automatic power changeover.
