I find that underground strip-armoiured,4core,LT PVC cables in an earthed power distribution sytem are occasionly found in charred condition-with no trace of it except ash. Is this because of no proper earth connection/continuity (giving rising to high armour resistance)in the joint enroute or because of insufficient capability (again due to high armour resistance)of cable-armour to carry fault current or due to neglected /unprotected overloading of the cable or due to high armour currents caused by power thefts where only phase(s) are unauthorisely tapped & at the point of poer consumption earth terminal is established by burring underground a not so good earthing rod (or using an underground water pipe for the purpose)1 2233
Why do we mix soda with water in LRS?1 5789
Role of active and reactive Power sharing in between two synchronized Generators, Droop Setting role ?
impliment (AB)`+C to transistor representation
if we look on phasor of the transformer vaoltage is 180 oppsite at primary and the secondary so to improve a power factor is secondary should kept negative to improve it primary side means is -.90 became +.90 at other side
how does directional relay work incase of ac ?
(1)WHAT HAPPENS WHEN SUDDENLY LOAD GIVEN TO THE INDUCTION MOTOR ? (2)CAN WE MAKE WOOD AS MAGNET ? (3)WHAT IS THE VALUE OF MAGNETIC FLUX DENSITY IN TRANSFORMER ? (4)WHY WE ARE USING ELECTROMAGNETI NOT ELECTROSTATIC IN MACHINE ?
How to calculate fault level of 11 KV system
What is the difference between AC and DC injection methods for rotor earth fault protection
how to check ac servo motor
is there any role of power factor with frequency variation? and how we can manage the frequency variation?
In AC if the direction of current keeps reversing every half cycle, how does it propogate through the transmission lines?
hai now i am working as a electrical design engineer in construction field can i get a job in oil and gass field or power plant project as a electrical design engineer?
Cables Construction hi friends, 0.6/1/1.2 kV LV , DC and Control cables are concentric copper conductor what does its means and what is the use of concentric copper conductor,and are this with copper tape shield or copper screening, ? thanks
any one guide me to reduce the power factor of diesel Generator from 0.97 Leg to 0.8 Leg.with out any change in my load.
The 3 phase 400 hp 440 volt slip ring induction motor do not take one phase amps why ? The motor is running good condition
how net resistance islow in star connection and viseversa in delta connection...? if anybody could explain in detail it wud be helpful.
