tell me what type of Turbine you use (gas turbine, Water turbine, etc.). And why you use arduino module, Micro turbines are not self-starting devices. They require a starter and a power source for the starter. The starter usually includes a powerful electric motor and a battery which acts as the power source for the starter. If the battery loses its charge or otherwise fails, the micro turbine cannot be started. To safeguard against battery failure it has been proposed that the starter for a micro turbine have an alternative source of power. Start a micro turbine and couple a micro turbine to an electrical load. The inventive power circuit’s direct starting power from a DC battery, an AC power utility grid, and/or another source of electrical power. An advantage of the invention is the use of minimal circuit components for a power circuit which couples a micro turbine to a load and to AC and DC starting power sources. Another advantage provided by the invention is to provide a backup starting power source that is available in the event of battery failure.
