Nvis 7018 Synchronous Machine Training System

Synchronous Machines are used as Generators in power plants because of their characteristic relation of speed with frequency. The study of power generators is the part of most of the curriculum.

NV7018 Synchronous Machine Training System is an exclusive product designed to demonstrate the fundamental concepts of parallel operation of Three Phase Synchronous Generators.

Students can learn the basics as well as advanced experiments and safety conditions with precautions that are encountered while generating power with multiple generators .

Various terminals including three phase starter terminals are provided on front panel to provide flexibility and ease of connections while performing experiments. Students can perform experiments like Synchronization of parallel generators using advanced and conventional methods, behavior of generator, load sharing, power transfer parameters, analysis of voltage regulation of generator, V curve and inverse V curve in Three Phase Synchronous Generators with a vast flexibility.
