Product Description

Description:

A self-contained motor and generator set that operates as asecond generator for Power System Trainer. It provides extra experiments andstudies into power generation. The motor and generator set consists of twocoupled machines mounted in the base of the control console. Manual or differenttypes of automatic excitation control the output of the generator. A vectordrive controls the speed of the motor. Digital meters show the conditions ofthe prime mover and generator. The relays show students how actual generatorsare protected and the different ways that they are protected. Students can setthe relays from their control panels. The relays also include sockets to linkthem to a suitable computer  for moredetailed programming, if needed. The relays operate the circuit breakers aroundthe second generator. The circuit breakers also include hand-operated switches,and lamps. The lamps show whether the circuit-breaker is open or closed.
