3 phase sequencing

[ardhuru]

Point taken!

I do have lots of experience with transformerless designs, interfacing mains directly with the PIC (as in X10 receivers and transmitters etc.), traic controllers and so on but like I said its the first with 3 phase. So, its more an issue pertaining to the timings involved, rather than electrical aspects.

1.0 Introduction
Protection of power system elements such as transmission lines, generators, etc., often requires accurate measurement of three-phase voltage to provide reliable fault detection and breaker operations to minimize power system disruptions.
