Sparky1550 said:Can I feed a 1200 amp 3phase AC electrical service with 2 separate 150kva power sources? (the sources being 150kva 120/208 3phase gas powered generators) Are there any issues with harmonics from seperately derived systems? Will each phases voltage still be 120v or by combing 2 seperately derived phases will the voltage become 208v or 240v etc?
The purpose of using two 150kva generators to feed a 1200 amp service is to ensure a reliable and consistent power supply. By using two generators, the load can be evenly distributed between them, reducing the risk of overload and increasing the overall efficiency of the system.
The power output of two 150kva generators is equivalent to a single 300kva generator. This means that both setups can handle the same amount of electrical load. However, using two smaller generators may be more cost-effective and provide a backup in case one generator fails.
A 1200 amp service is able to handle a large amount of electrical load, making it suitable for powering commercial or industrial buildings. In this setup, it serves as the main electrical service that is being fed by the generators.
When selecting the appropriate size of generators for a 1200 amp service, factors such as the type of load being powered, the duration of usage, and the potential for future growth should be considered. It is important to ensure that the generators can handle the expected load and provide enough power to meet the building's needs.
The generators should be regularly maintained and serviced according to the manufacturer's recommendations. This could range from monthly to annual maintenance depending on usage and other factors. Regular maintenance helps to ensure the generators are functioning properly and can prevent costly breakdowns or failures.
