一般說明
The Three-phase Installations Faults Application, "AEL-AD33T", has been designed to study several protections belonging to industrial installations. Through safety elements, the students 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 three-phase transformer in order to simulate earth derivations under safety conditions.
It is also possible to change the configuration of ground connection of the charges connected to the system. Some of those configurations are: TN, IT, TN-S, TN-C, TN-C-S.
Besides, the following protections are included: protection by earthing, protection by differential circuit breaker with automatic reset and protection by differential circuit breaker with variable sensitivity.
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 sensivity of the protections.
