WHY HOLDING CONTACTOR OF MOTOR STARTER IS CALLED NO VOLT
COIL.
Answer Posted / jerald xavier
In Motor Starter circuit, The load (Motor) is Normally Open
untill the voltage coil is energised. The working of this
coil is mainly dependent on the voltage, and there is no
importence for current in this coil,hence the name NO
voltage coil.
'N' stands for Normaly, 'O' stands for Open

As we use capacitior bank in 3ph ckt for improvement of PF, why not we use capacitor in single phase domestric use, at our house their are many inductive equipments,like fan,mixer,tube choke,air conditioner they also draw PF... by using capacitor can they improve PF. if yes--what are advantage and how to connect a capactor in single ph,and which type of capacitor if no- what are disadvantages.
