AEL-AE4 Differential Automatic Switches Application
The AEL-AE4 Differential Automatic Switches Application is an educational training system designed to provide practical understanding of differential protection and earth leakage faults in electrical installations. It enables students to study how a differential protection switch operates when an earth leakage occurs and to investigate its sensitivity under different fault conditions. The application uses a variable resistor load to create controlled earth leakage faults, allowing users to determine the trip current threshold of the differential switch. Integrated measuring instruments, including an analog voltmeter and ammeter, support the measurement of fault currents and contact voltages. AEL-AE4 is suitable for technical, vocational and higher-education electricity laboratories, providing hands-on training in electrical protection and fault analysis.
