EVALUATION OF THE MEDIUM VOLTAGE CABLE LINE (SKTM) 20 KV USING TAN DELTA AND PARTIAL DISCHARGE METHODS

Abstract

Distribution network with cable system requires maintenance to maintain the level of reliability. Many factors affect the reliability of this cable system, one of which is environmental factors that can cause deformation of the cable so that it is likely to affect the dielectric condition of the cable. Therefore, to determine and ensure the reliability of the cable system so that it can be known whether a cable is reliable or not, a cable condition diagnostic system is needed that can access the existing cable conditions in the field. Tan Delta (Dissipation Factor) and Partial Discharge are tests that can diagnose the condition of cable insulation in the field based of IEEE standard 400.2 and IEEE standard 400.5.
