What is a Lima Mac generator?

The . principal design concept of the Lima® MAC generator is to provide electrical power to operate three phase induction motor loads having operating power factors in the range of0.8 to 0.92, with voltage regulation well within public utility standards. 3 Receiving Your New Lima"' MAC Refrigeration Duty Alternator.

Does my Lima® Mac generator need maintenance?

Routine Maintenance. Your Lima® MAC generator has been designed to be as reliable and trouble free as is possible. However, costly repairs and down time can be minimized by operating the unit under conditions that are compatible with those at which the equipment was designed to operate.

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.

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.

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).

Does the Lima Mac refrigeration duty alternator have a voltage regulator?

General. The Lima® MAC Refrigeration Duty alternator is a self excited, self voltage regulated synchronous AC generator, and does not employ an automatic voltage regulator. The main stator and exciter stators are housed in the generator frame.
