In EDO ACBs what is a purpose of closing coil and motor, what is the operation of these devices are they inetconnected. means if we give supply to motor and by BCS we charge Closing coil,what exact is operation is and how it charge a spring of ACB. Sir if anybody has an wiring diagram please send me the link to operate and EDO breaker.
what deference between panel earth and systemearth
In control valve proximity inductive sensor is taken as digital feedback for full open and full close.Normally its volts 24v when the sensor acts the feed back voltage 14v so that our relay not indicating in plc panel . kindly give the solution.
After doubling voltage from solar cells & use step down voltage transformer can we get high current output with low voltage.
