Power transmission overhead line online monitoring [8] was implemented in some countries. This paper mostly discussed about the monitoring of power transmission cables. In densely populated cities overhead transmission has a limit. More over faults are more in overhead transmission due to damage in conductors, birds, temperature, wind and so on. These drawbacks can be avoided to a large extend through underground cables. If it is monitored real time its power transmission capability and reliability can also be increased. Even though this is a costliest type of transmission cables, are adopted in cities. In addition to the underground cables, power cables are used in industry to carry the power from control station to the site. Cable trenches and cable trays are used for this.
