Three phase circuit failure montoring

Can anyone lead me to any resources on how to make a phase detector circuit that monitors a 3 phase line (230v AC, 50Hz) for either failure or phase change. The detctor should be able to detect an open phase or a phase-to-phase short. Then get the status and forward it to a microcontroller.

 

any ideas?
