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