Can someone explain this circuit to me?

It's from a unit that measures power factor. The three phases are measured to ground through op amps and sent to an ADC.

Then there's three op amps set up as difference amplifiers which measure phase A to B, B to C, and C to A.

The outputs of these difference amplifiers go into three circuits like pic related (That's a comparator, not an op amp).
Is it for detecting zero crossing or something?
