GIL Delivers Feeder Line Protection System

Our Success story this month comes from our panel solutions team for an Oil&Gas multinational Customer. Customer requirements include LV&MV Power System Line Protection system.


GIL designed, built and tested a line protection system with some special features, such as-

  1. During fault, the only circuit breaker closest to the fault point should be tripped.
  2. If the circuit breaker closest the faulty point fails to trip the circuit breaker just next to this breaker will trip as back up.
  3. The operating time of relay associated with protection of line should be as minimum as possible in order to prevent unnecessary tripping of circuit breakers associated with other healthy parts of power system.

Within 3 weeks from shop drawing approvals, design, build and factory acceptance tests were concluded at GIL facility in Lagos Nigeria. During the Factory Acceptance Test, there were series of functional tests carried out in accordance with IEC61439-2 requirements.

  1.  Panel power-up and fusing testing
  2.  Continuity testing
  3. Injection Tests
  4. Operating interface
