To our familiesJoanne and sons Stephen, Brian, Jeffrey Mottershead and their familiesVictoria, Kristina, and Kayla BombenSusan KlempnerJackie, Livnat, and Yigal Kerszenbaum,andTo the operators, technicians, and engineers in the power stations around the world who keep the lights on and the power flowing around the clock through adverse conditions for the benefit of everyone.

Hydro generators in different plants are rarely identical, and it is not uncommon for small, medium, or large utilities to have a significant variety of unit sizes, origins, and vintage in their fleet of generators. Among these generators, there might be units 60 or more years old with all original components including stator windings due to the robust nature of this class of machinery. Some might still have a pilot and main rotating exciter or a static pilot with a main rotating exciter, or have full static excitation. Additionally, there may be units operating over a wide range of rotating speeds in 50 and 60 Hz power grids with a few still operating at 25 Hz or other frequencies. All are designed and built by a long list of manufacturers from around the globe using a variety of materials and methods governed by different standards. These generators are still owned by traditional utilities and also owned by new deregulated independent power producers (IPPs) that acquire traditional utilities from all over the world. There are new large hydro plants still being built for traditional utilities and IPPs to the most modern design standards and manufacturing methods. The owners of all types are called upon to operate and maintain an incredibly wide variety of machines.
