What is the difference bet ween EDO Type & MDO type ACBs, and what is the advantage EDO Type over than MDO type ACBs.
2 61987We 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 5825what happens if power factor is maintained at 0.9?give me the answer in technicall way rather than telling the penality n all

write down the formula of cable size in RM if current is 50Amp.
A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?

we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.
