in the 3 phase motor , if u change the connection of 2 phases the motor will rotate in the other direction .
so if the main supply had a fault and the operator change 2 phases wrongly , it will be very bad mistake .
is there is any relay which can detect this fault and control it
i know we can prevent this problem by using a microcontroller and " converter and inverter " circuites .
but i look for a solution by using the relays
can anyone help ?!!
