  1. PRACTICAL METHOD FOR ANALYSIS OF GROUND FAULT CURRENT DISTRIBUTION ON GROUNDING SYSTEM OF LARGE HV SUBSTATIONSI. Among outgoing lines there is no any one of double circuit parallel lines Ljubivoje M. Popović

  2. GROUND FAULT CURRENT COMPONENTS IN THE CASE OF FAULT INSIDE THE STATION

  3. GROUND FAULT CURRENT COMPONENTS IN THE CASE OF FAULT AT AN LINE TOWER IN THE VICINITY OF THE STATION

  4. IDEALISED PHYSICAL MODEL OF AN ACTUAL OVERHEAD LINE

  5. EQUIVALENT CIRCUIT OF AN OVERHEAD LINE UNDER GROUND FAULT CONDITIONS

  6. THEORETICAL BECKGROUND OF THE METHOD1. METHOD OF SIMETRICAL COMPONENTS2. EQUIVALENT VOLTAGE SOURCE AT THE FAULT PLACE, OR THEVENEN GENERATOR 3. DECOUPLING TECHNIQUE, SEPARATE CONSIDERATION OF CURRENTS APPEARING AS A CONSEQUENCE OF INDUCTIVE CONNECTIONS AND CURRENTS APPEARING AS A CONSEQUENCE OF CONDUCTIVE CONNECTIONS 4.
