Synchronous Machines are used as Generators in Well as Conventional Lamps (Dark Lamp Method) to
power plants because of their characteristic relation of perform the synchronization of two generators. Students
speed with frequency. The study of power generators is can learn the basics as well as advanced experiments and
the part of most of the curriculum. 46580 “Synchronous safety conditions with precautions that are encountered
Machine Training System” is an exclusive product while generating power with multiple generators . Various
designed to demonstrate the fundamental concepts of terminals including three phase starter terminals are
parallel operation of Three Phase Synchronous provided on front panel to provide flexibility and ease of
Generators. This product is equipped with advanced connections while performing experiments. Students can
measurement system for AC Parameters and DC perform experiments like Synchronization of parallel
Parameters. It has inbuilt which is highly stable and generators using advanced and conventional methods,
accurate. Due to use of big size LCD display it is behavior of generator, load sharing, power transfer
possible to observe mul t iple parameters parameters, analysis of voltage regulation of generator, V
