Protection of Parallel-connected High Voltage Transmission Lines
Used mainly for protecting parallel-connected lines, the directional overcurrent protection relay is tested through fault simulation here, besides being analyzed and investigated experimentally in terms of selectivity and speed. Networked via a bus system, the protective relays can be operated and evaluated by means of the SCADA Power-LAB software.

Note: This Training System is a Supplement Equipment Set to the:

Training Concepts:
  • Protecting parallel-connected lines with different overcurrent time relays
  • Parallel operation in the fault-free state
  • Determining minimum response values for non-directional overcurrent time relays
  • Determining directions of protection for directional overcurrent time relays
  • Time grading for overcurrent time relays
  • Determining minimum response values for directional overcurrent time relays
  • Checking selectivity through combined overcurrent and directional measurements
  • Networking protective measures
