What is the difference bet ween EDO Type & MDO type ACBs, and what is the advantage EDO Type over than MDO type ACBs.
2 62121We have a 33/11kv switchyard having 12.5 MVA power transformer. We export & import power through this transformer. When we export power, the PF will be depend on GRID PF & when we import power the PF will be depend on our load PF. but the problem is that,when neither we export nor import but our 33KV vCB is in close position,our meter read the power factor 0.14 to 0.25 at that moment. So how can be we improve the power factor at that moment.
3 5903what happens if power factor is maintained at 0.9?give me the answer in technicall way rather than telling the penality n all

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.
Actually I have a doubt on neutral and earth.we use Ac power without taking neutral by connecting to earth,but at that time does it affects on efficiency of any electrical components or no? If yes how?
