Carry out the tray of study of the selectivity of protections
distributions in low voltage highlights the concepts of selectivity
and ammeter chronometric.
It allows
The use of a relay adjustable differential with a torus separates
the causes and the effects of currents of short-circuits, their
modes of calculations and the choice of the protections
The principles and the operating characteristics of a mains supply
circuit breaker
The use and the trace of a trip curve for a particular size
The simulation of situations of selectivity power total partial and
non-selectivity
The study of the concepts of selectivity to2 or 3 floor and their
consequence and effects on an installation
The choice of the impedance of the fault loop by the chokes of
modular values
The presentations simplify of the cut by the electric arc in very
low voltage and the limitation of the short-circuit current.
