The company specialized in electrical engineering SEMAP offers its customers a complete commissioning of substations as well as high and low voltage transformers (HTA / HTB). Its qualified specialists provide the necessary test tests to then proceed to the required transformer commissioning.

Electrical tests:

  • Check the polarities.
  • Current and voltage transformer test (with primary and secondary injection).
  • Auxiliary service check (400/230 V AC).
  • Verification of local cells, protection and MV cells.
  • Test protections and feedback to CCN.
  • Lock test.

Selectivity study and parameterization of relays.

Diagnosis and repair of defects (events, petrograph ...).

Functional test, secondary and primary injection for all types of relays (SIEMENS, GE, ABB, SCHNEIDER, EFACEC ...)

Theoretical and practical training
