Transmission Line Protection

A transmission line is long, exposed and electrically complex, which is why its protection is the most demanding application in the discipline. This course covers it in depth. Delegates work through line parameters and fault behaviour, distance protection zones, characteristics and the settings that follow, and the effects that mislead a distance relay including infeed, mutual coupling on parallel circuits and series compensation. Differential and directional comparison schemes are covered along with the signalling they depend on. Autoreclosing, single pole tripping and the coordination between them complete the programme, and the course closes on analysing a real line fault record.

Course objectives

  • Calculate line parameters and analyse fault behaviour
  • Set distance protection zones and select characteristics
  • Account for infeed, mutual coupling and series compensation
  • Apply differential and directional comparison schemes
  • Specify the signalling a unit scheme depends on
  • Configure autoreclosing and single pole tripping
  • Analyse a line fault record and explain the relay's behaviour

Who should attend

  • Protection engineers and technicians
  • Transmission and utility engineers
  • Testing and commissioning staff
  • Consulting engineers in power systems
  • Control centre engineers investigating events
