Transmit ADC Sensor output Value over 5 Meter via CAT6 Cable to Atmega32A
You might also put an opamp on the ouput as a voltage follower(or scale the output to have a wider range), to 'protect' the sensor output a bit, or use a voltage to frequency...

3 phase motor voltage
A motor is never wired with a neutral line connected, it's alwas 3(or 6 + ground)wires for a three phase motor. The lowest voltage on the motor is the winding voltage, and thus...
