Introduction: Phase sequence detection system has been specifically designed keeping in mind an essential point of detection of correct phase and protection of equipments by over voltage.
Basically it is useful to connect the any m/c to supply. Because if the phase is not correct and connection establishes than it may be damage and burn out the winding of machine.
This phase sequence detection and controlled power supply system is basically divided into two parts:-
1. Phase Sequence
2. Protection from supply voltage
i. Under Voltage Protection
ii. Over Voltage Protection
