Description
The Single-Phase Installations Faults Application, “AEL-AD33”, has been designed to study several protections belonging to home installations. Through the safety elements, the student can simulate different faults and verify the reasons why each type of protection acts. It includes some innovative electric devices for the protection of people and installations against the effects of electric current, which ensure the continuity of power availability, as well as people safety. It includes a single-phase transformer to simulate earth derivations under safety conditions. It includes protections for: differential protection with automatic reset and differential protection with variable sensivity.
To check all protections, a variable resistor is included to control current derivations. It also has meters to know the amount of derivation current and verify the protection´s sensitivity.
