Electrical Cables Capacitance grading of cable implies Capacitance required to be introduced at different lengths to counter the effect of inductance Grading according to capacitance of cables per km length Cables using single dielectric in different concentrations Use of dielectrics of different permeabilities Capacitance required to be introduced at different lengths to counter the effect of inductance Grading according to capacitance of cables per km length Cables using single dielectric in different concentrations Use of dielectrics of different permeabilities ANSWER DOWNLOAD EXAMIANS APP
Electrical Cables Solid type cables are considered unreliable beyond 66 kV because Of corona loss between conductor and sheath material There is a danger of breakdown of insulation due to the presence of voids Insulation may melt due to higher temperature Skin effect dominates on the conductor Of corona loss between conductor and sheath material There is a danger of breakdown of insulation due to the presence of voids Insulation may melt due to higher temperature Skin effect dominates on the conductor ANSWER DOWNLOAD EXAMIANS APP
