We Claim:

1. A system for detecting a fault in an overhead power line having a plurality of sensors on a first conductor and a second conductor, the overhead power line suspended by a plurality of transmission towers spaced along a length of the overhead power line, the system comprising:

a first sensor from the plurality of sensors positioned on the first conductor, a second sensor from the plurality of sensors positioned on the second conductor, wherein the first sensor and the second sensor are at a first and second pre-determined distances respectively from a first transmission line tower,

wherein the first sensor and the second sensor are configured for measuring one or more electrical parameters of the overhead power line, wherein measuring comprises compensating based on transmission line characteristics of the overhead power line and the pre-determined distances, wherein each of the plurality of the sensors is configured to communicate with at least one other sensor for communicating electrical parameters to a fault detection unit for detecting the fault in the overhead line

2. The system of claim 1 wherein at least one sensor is designated as a master sensor to communicate with at least a select group of sensors from the plurality of sensors, and to receive the measured values from the select group of sensors; and

a fault detection unit configured to communicate with the master sensor to receive the measured values, wherein the measured values are used to detect a location of fault in the overhead power line.

3. The system of claim 2 wherein the plurality of sensors communicate with each other and the master sensor such that the measured values from each sensor reaches the master sensor in a hopping pattern from one sensor to an adjacent sensor, till the adjacent sensor is the master sensor.

4. The system of claim 2 wherein each sensor is configured to communicate in a predefined pattern with at least one other sensor.

5. The system of claim 2 wherein the master sensor is configured to aggregate the measured values from each sensor to generate aggregated measured values and is further configured to communicate the aggregated measured values to the fault detection unit.

6. The system of claim 2 wherein the fault detection unit is a ground unit assigned for the transmission tower.

7. The system of claim 1 wherein the fault detection unit is a remote control center assigned for the transmission tower.

8. A method for detecting a location of fault in an overhead power line having a first conductor and a second conductor, suspended from a plurality of transmission towers along a length of the overhead power line, the method comprising:

positioning a first sensor on the first conductor along a first axis perpendicular to the first conductor, and positioning a second sensor on the second conductor along a second axis perpendicular to the second conductor, wherein the first axis and the second axis are at a first pre-determined distance and a second predetermined distance respectively from a first transmission line tower from the plurality of transmission towers;

configuring the first sensor and the second sensor for measuring one or more transmission line parameters of the overhead power line to obtain measured values of the one or more transmission line parameters by including a compensation factor, wherein the compensation factor is based on transmission line characteristics of the overhead power line and the pre-determined distances; and

using the measured values of the one or more transmission line parameters for detecting the fault on the overhead power line.

9. The method of claim 8 further comprising:

positioning a plurality of sensors on the first conductor and the second conductor, wherein each of the plurality of sensors on the first conductor is configured as the first sensor, and each of the plurality of sensors on the second conductor is configured as a second sensor;

configuring each sensor to communicate with at least one other sensor from the plurality of sensors, and designating at least one sensor as a master sensor to communicate

with at least a select group of sensors from the plurality of sensors, and to receive the measured values from the select group of sensors; and

communicating the measured values from the master sensor to a fault detection unit for detecting the location of fault in the transmission line.

10. A sensor for measuring one or more transmission line parameters of an overhead power line, wherein the sensor is located on a conductor of the overhead power line, at a predetermined distance from a first transmission tower carrying the overhead power line, the sensor comprising:

a sensor processing unit to obtain measured values of the one or more transmission line parameters by including a compensation based on transmission line characteristics of the overhead power transmission line and the pre-determined distance; and
