Fault Analysis in Multi Inverter

Electricity has become the most sought after amenity for all of us. Gone are the days when electricity would be only limited to cities. It is now reaching to every distant parts of the world. So we have now a complex network of power system. This power is being carried by the transmission lines. These lines travel very long distances so while carrying power, fault occurring is natural. This fault damages many vital electrical equipment like transformer, generator, and transmission lines. For the uninterrupted power supply we need to prevent these faults. So we need to detect faults within the shortest possible time. Microprocessors and microcontroller based systems used for these fault detection have been advancing rapidly.

In our project we have designed a system which consists of two inverters. These inverters can be provided with power supply either directly through 3 phase supply or through a step down transformer. Usually the inverter provides uninterrupted supply to the system there are also cases where the inverter shuts down due to unidentified faults. During this time the secondary inverter connected will automatically get connected and helps to run the system as it did before.
