Using Pylon Tower Test Kits with the Sonel ERP-1 pylon tower testing adapter and the Sonel MRU-120 and Sonel MRU-200 series of earth resistivity meters makes the measurement of the earth resistance of transmission line pylons and the earth resistance of the pylon tower footings easy to perform.
The adapter is suitable for the earth resistance measurement of different types of towers and pylons such as Prestressed Concrete, Reinforced Concrete, Steel Lattice Construction and Steel Tube Construction. Testing of lattice towers is possible without the need to switch off the line or disconnect the control connections, ensuring the tests are both safe and easy to perform.
The flexible current sensor is wrapped around each foot of the pylon, with a more accurate result of the earth impedance possible by making more than one coil around the tower leg. The resistance measurements of each pylon foot can then be used to calculate the overall resistance of the pylon.
The Sonel MRU-200 and Sonel MRU-200-GPS can also check the direction of the current when making the measurements which can help identify if there is any damage, such as corrosion to the steel strip.
With the addition of an integrated GPS receiver the Sonel MRU-200-GPS can store the location along with the associated earth resistance measurements of the pylon tower under test.
