Generator Exciter Cooling

Large utility hydrogen cooled generators sometimes require a source of excitation power from an external source. This power is created from a small air-cooled generator which has its own system of cooling equipment.

air-cooled generator range from a single cooler horizontal design to a multi cooler vertical mount design.

With the generator exciter cooling, the heat generated by electrical losses as well as frictional windage losses is removed from the generator. This ensures appropriate temperatures and operational performance.
