Three Phase Fault Analysis for Temporary and Permanent Fault Based on Microcontroller

Abstract

The electrical substation which supply the power to the consumer, have failures due to some fault which can be temporary or permanent. These faults lead to substantial damage to the power system. The faults might be LL, LG, over voltage in the supply system and these faults can affect the power system. To overcome this problem a system is built, which can sense these faults automatically using microcontroller. For power to be useful in a home or business; it comes off the power station and is stepped-down to the suitable level of voltage. It is the transformers that step up the voltages or step down the voltages according to consumer’s requirement. We can say that Transformer plays important role in our Power System.To maintain reliability in power system it is important to protect the 3 phase devices like inductive, resistive, etc. against various faults occurring in it. This fault should be identified and analyzed quickly for their remedies. The aim of our project is to study and implement various fault detection technique and monitoring system.
