Motor-generator (MG) sets provide load isolation for computers and other sophisticated electrical systems. They can also perform frequency conversion and are used for transformer testing.
With input of 50 or 60 Hz, output frequencies of 50, 60, or 400 Hz are available as standard. For custom designed systems, fixed frequency outputs from 25 Hz to 1200 Hz may be selected, or we can provide continuously variable frequency using a VFD on the motor. Power capacities range from 10 kVA to 20,000 kVA and up, depending upon system requirements.
Typically, Kato Engineering furnishes a factory-programmed PLC control panel to provide a complete power conversion or isolation system. The panel is usually unit-mounted but can also be free-standing or wall-mounted. The panel will include the motor starter, output circuit breaker, metering, protective relaying, a voltage regulator and any other required components. Manual and automatic paralleling is also available.
