SCT-PPT excitation systems were supplied for gas and steam turbine-generators from 1960 through the 1980s in the 5 to 250 MVA range. These compound type exciters have both a Saturable Current Transformer (SCT) and a Power Potential Transformer (PPT). Their primary attribute is the ability to support transients in generator load due to single or 3-phase faults or starting large motors even with reduced terminal voltage.
