Hi guys,
I want to find a Frequency detecting cct or a chip for 300V power line. It
is to be measured small fluctuations around 50Hz Domestic supply line
frequency.

"small fluctuation" being what ?

Something low cost, and out of the box ? : see www.daqarta.com

Absolute precision matters ? - Divide by 50, and phase compare with
the 1pps from a GPS system ?

More interested in Phase or Energy deviations ?

If you told us what part of Homeworkia this had to work in, that would
help....
