Synchronous Generators
There are two commonly used types of generators. They are both synchronous and inductive.
Synchronous generators are mainly used as an emergency power source and are often times used as the sole source of all power requirements in an in any given area. When the generator is used as the sole power source, it must be large enough—that is, the KVA / KW rating must exceed the demand by no less than 20% to handle the high peak loads of the operation. In addition, switchgear and paralleling equipment is often installed to simultaneously operate the generator with the utility.
Induction Generators
Induction generators are used as peak-saving options. Induction generators provide power to withstand additional loads or demands, such as air conditioning in the hot months of the year, starting large machinery, etc. Induction generators produce power only from a parallel power source, such as another generator or the local utility provider. Induction generators cannot operate independently of another power source, therefore it’s beneficial to work with the local utility provider to gauge the operation's peak KW demands to help in sizing the induction generator.
There are several factors that need to be considered before purchasing a diesel generator, such as, the transfer switch size, additional fuel tank requirements, enclosure options and fuel consumption. If you are in need of a synchronous or induction generator, give Vital Power and Equipment a call, and we will assist you in sizing your diesel generators or natural gas generators and provide you with the best possible solution for your backup, standby, or prime power needs.
