i am working on a project related to alternator synchronization.for this i need to compare 2 frequencies,2 voltages and also match phase sequences of 2 alternators.please if anyone out there can help me with the programming part for the same.
freq - 50hz
3 phase voltage
Sure, post what you have so far and we'll help from there 
Hi,
Before programming, what is your method of detecting phase sequence, frequency and voltage to accomplish this?
Have you done any research?
Googled.......
