An automatic transfer switch is an integral component of an emergency power supply system (EPSS). Auto transfer switch (ATS) consists of different electrical and mechanical components such as magnetic contactor, relay, timer, over under voltage relay etc. Basically maintenance includes scheduled and unscheduled renovation works. Efficiency of auto transfer switch (ATS) can be increased by using proper operation & standard maintenance schedule. Maintenance procedures are normally used to reduce unexpected problems of auto transfer switch. Proper installation, commissioning, operation, maintenance & troubleshooting procedure have been discussed thoroughly in this project report. A large number of real pictures have been shown to make the report more useful to all. It has been tried to provide a good understanding of the ideas about proper operation, maintenance & troubleshooting of auto transfer switch. Some auto transfer switches allow load shedding prioritization of optional circuits, such as heating and cooling equipment. More complex emergency switchgear used in large backup generator installations permits soft loading, allowing load to be smoothly transferred from the utility to the synchronized generators, and back; such installations are useful for reducing peak load demand from a utility. In cases where two independent utility feeders are available, a fast load transfer can be achieved by the use of a static transfer switch. When the critical load includes a load transformer, the transformer is subjected to transients during the transfer interval. Therefore following a load transfer, a transient current flows into the transformer which can cause a post transfer voltage sag. Fault disturbance characteristics which determines voltage difference between the sources and the voltage drop across t he incoming and the outgoing thyristor switches during the load transfer process.
