Lima Double Power Station Generator

What is a Lima Mac generator?

Designed for 1 hp/kW, 3 phase, Code G motor starting capability, the LIMA®MAC generator is self-regulated and self-excited, providing maximum reliability without external voltage regulation, adjustments, or electronic controls . . . a "hands off" generator supplying simplicity with minimum maintenance for any application.

What is the X d of a Lima Mac generator?

The LIMA®MAC line of generators have relatively low sub-transient reactances (X"d). The actual values of X"d will differ among the various models, but will range in the area of 9.5% (.095 PU) to 6% (.06 PU).

What are the advantages of a brushless Lima®Mac generator?

An important consequence of brushless design and the self voltage regulating features given in paragraphs 1 and 2 above is that, as a brushless unit with no brushes, and no arcing conductors, the Dripproof LIMA®MAC generator is suitable for operation in Class I, Group D, Division 2, Temperature Code T3 hazardous locations.

Can a Lima Mac generator sustain a fault?

This same inrush current sustaining capability, 500% of full load current, also enables the LIMA®MAC generator to sustain fault currents of the same magnitude to assist in fault clearance, without the need for an external excitation support system such as a Current Boost, Series Boost, or PMG as is required by a conventional brushless generator.
