Selectivity Educational Equipment
Specification
Carry out the tray of study of the selectivity of protections distributions in low voltage highlights the concepts of selectivity and ammeter chronometric.
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
