WebUnearthed cable has more insulation strength as compared to earthed cable. When fault occur phase to ground voltage is √3 time the normal phase to ground voltage. So if we … Unearthed cable has more insulation strength as compared to earthed cable. When fault occur phase to ground voltage is √3 time the normal phase to ground voltage. So if we used earthed cable in unearthed System, It may be chances of insulation puncture. So unearthed cable are used. See more In HT electrical distribution, the system can be earthed or unearthed. The selection of unearthed or earthed cabledepends on distribution system. If … See more Earlier the generators and transformers were of small capacities and hence the fault current was less. The star point was solidly grounded. This … See more As a thumb rule we can say that 6.6KV unearthed cable is equal to 11k earthed cable i.e 6.6/6.6kv Unearthed cable can be used for 6.6/11kv earthed system. Because each core of cable have the insulation level to … See more Today generators of 500MVA capacitiesare used and therefore the fault level has increased. In case of an earth fault, heavy current flows into the fault and this lead to damage of … See more Webcable, the permittivity of the dielectric around the conductors is generally two to four times the dielectric constant 0. In addition, the spacing between each cable conductor and ground is usually much smaller than that of an overhead line, so the cable will exhibit much higher capacitance than an overhead line with the same length. script in flow designer
