| On-site generators are of growing interest to many customers, from
homeowners to larger key accounts. Power suppliers need to understand essential concepts of
generators, including sizing procedures, advantages of each fuel type, and options for
switchgear. Knowing each step in sizing the generator is critical, particularly the effect
that motors and their start-up current have on the generator. A complete discussion of
transfer switches is provided, using common examples of manual vs. automatic start
applications. More advanced arrangements for interconnection with the grid are explained,
including parallel generation and other interconnect issues. This is non-biased training
that delivers “application-oriented” knowledge on all aspects of a good
installation. |
