SOR compound is a specially formulated compound having high current conductive & Rust Resistance property, Absorbing
& retaining the moisture for long period. It reduces the ohmic value of soil & helps in Faster dissipation of fault current. Sor compound will be used around the earth electrodes at the time of installation. SOR compound is to reduce the resistance between electrodes and soil and to create a low resistance zone around the electrode to create a uniform environment so that the electrode output is constant. Sor compound used as backfill material.
