Basically this is a automatic controller or mean to say
that a automatic controlling switch mainly used for control
the voltage of any source, load or any electrical network.
Its main uses are automatic operation of OLTC (on load tap
changer) for a Power Transformer, to regulate the
excitation voltage in generator, temp control of electrical
furnace etc.

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.
