Abstract :
The 20 KV medium-voltage distribution network system (SKTM) in urban areas is fully using the cable system. 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 on these tests, the condition of the cable can be determined whether it is in good condition, needs regular maintenance or is in bad condition. In this Final Project, the Cable Assessment is carried out on the Discussion & National Conference feeders with the aim of knowing the condition of each feeder's cable. The condition of the cable in the feeder. Discussion after the Tangen Delta test is carried out, there is no need for action with an estimated re-test after 5 years. For Partial Discharge testing, it gets point 4, namely the status of the Alert cable with an estimated re-test after 1 year. While the condition of the cable at the National Conference feeder after the Tangen Delta test is No Action Needed with an estimated re-test after 5 years. For the Partial Discharge test, you get point 6, namely the status of the cable is very bad with an estimated test return after 3 months. This test refers to the standards used, namely IEEE 400.2, for Tangent Delta and IEEE Standard 400.5 for Partial Discharge.
