ofcourse the power factor is the cosine of the angle
between voltage and current.for the good system the power
factor should always tends to one.but practically
maintaining unity power factor is difficult.maintaining
unity power factor would consume less current and gives
high power.

what is the differance between HT motors And LT MOTORS.
What is the de rating factor of cable? What is the importance of the de rating factor in cable select
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 ?

which IS or IEC is used for earthing,breakdown voltage of transformer oil, hv/pd testing and all type of electrical testing
1 “earthing” for bonding of equipment and circuits to common plant earth electrode potential, 2 “protective earthing (PE)” when this bonding is required for personal safety provisions 3 “grounding” for interference suppressing bonding of screens, sys-tems with ground level 4. low-impedance earthing ? 5.primary earthing system and secondary earthing system what is that? 6.earthing electrode or mesh net earthing electrode ? very confusing , simple but very informative help required ? i will be very very thankful to you guys.
which are the criterias needed to select the kind of neutral earthing(solid earthing,resistance earthing,etc.) at various voltage levels in electrical distribution?
