AEL-AE5 保护继电器控制应用

The Protection Relays Control Application, "AEL-AE5", has been designed by EDIBON with the objective of understanding the operation of this type of relays.

This application is composed by the next kind of relays:

• Over current relays which open the circuit when it detects a high level of current previously configured.
• Leakage grounding relay capable to detect possible leakages to ground.

To measure the currents, it is included current protection transformers, and to control the system, a three-pole contactor. Thus, the student can understand the working of the protection relays and simulate some scenes, such as, leakage grounding, through the elements included in this application.
