The TDS generator specialist engineers are experienced in all types of excitation systems, from old shaft driven DC rotating generator exciters with amplidyne control, rotating exciters, alterex, or static exciters. TDS engineers are experienced in the static exciters from buss fed SCT-PPT exciters with analog regulators to the newer digital EX2000 regulator and excitation transformer or P bar winding. TDS even has experienced start up support for the EX2000/LCI for the static start of the large gas turbine generators.

These engineers are familiar with the excitation systems of small generators used on industrial units to large nuclear or fossil utility size generators. Many of the smaller generators utilize an Electric Machinery Rotating Exciter and OEM voltage regulator. Others use a buss fed static exciter. The TDS engineers are experienced in steam and gas turbine generator systems and up to 1100 megawatts. Many of the larger generators incorporate a small A/C generator to supply the recitifiers of the generator exciter system, also know as an Alterex. The newest of the large generators now utilize a P bar winding in the main generator to supply the power for the excitation system. TDS can service all these systems and system power sources.

The following is a listing of the exciter systems applicable to both steam and gas turbine generators, that TDS can service and support:
