Building Protective System

Product Code : SCL-EELE-11923

Training Objectives

  • Using an adjustable differential relay with separate ring core.
  • Analysing the causes and effects of short circuit currents (calculation methods, choice of protection devices).
  • Studying the operating principles of a thermal-magnetic circuit breaker (tripping curves, breaking capacity).
  • Using and drawing the tripping curve for a given rating.
  • Implementing selectivity between upstream and downstream protection devices.
  • Simulating situations of full selectivity, partial selectivity and non-selectivity.
  • Studying the notions of selectivity with 2 or 3 stages (consequences and effect on an installation).
  • Selecting the impedance of the fault loop via induction coils with modular values.
  • Presenting, in a simplified way, the principle of breaking via an electrical arc under very low voltage.
  • Limiting the short circuit current.


Presentation
This bench is designed to study and implement two selectivity strategies for protection devices in low voltage distribution systems:

  • Ammeter selectivity.
  • And chronometric selectivity.

Two isolating transformers enable limitation of the energy level involved when creating the deliberate faults required for the study.

Description

  • The bench is mounted on a frame with locking wheels.
