EEA: Electrical Energetics Grid Impedances, Short Circuit Currents, Automatic Trip-Out Ability and Ground Integrity (ADK: D-5/909)
The acquired knowledge is focused on assuring of safety conditions and protection against electrical shock by evaluating of automatic tripout ability and tripout time. Additional factors are used in calculations to protect transformers and built-in equipment in case of overheating. Several procedures and measuring methods are explained for maintenance in safe manner when work energized. The candidate will gain knowledge of evaluated parameters, the suggested limits from the standard and the examples of PASS / FAIL results. The responsibility of the candidate is the correct reports and markings and the appropriate acting and informing.
Areas of Application
- Short-circuit currents in three-phase a.c. systems:
- contribution of power station units,
- contribution of windpower station units,
- industrial transformers and belonging installations.
- Automatic trip-out ability, earth bonding, dR Hi-Current testing.
- Available short-circuit current at the test point, fuse characteristic evaluation, hot factor calculation and Isc minimum, background for arc flash and shock hazard present warnings and protection, incident energy & working distances, approach boundaries.
- Short-circuit currents maximum and calculation of contact & touch voltages in case of fault.
- Protection against electrical shock.
- Low-voltage switchgear and controlgear – circuit-breakers in case of leakages, neutral currents or asymmetry.
