AEL-VTFP Application de Bases du Transformateur de Tension pour les Dispositifs de Protection

The Voltage Transformer Fundaments Application for Protection Devices, "AEL-VTFP", has been designed by EDIBON to show the students which the main functions of voltage transformers are and which the parameters that must be considered in order to choose the adequate voltage transformer are.

The AEL-VTFP allows the student to check the transformation ratio of the voltage transformer and checking the class of accuracy. These maneuvers can be realized with or without earth fault on the primary side.

The AEL-VTFP consists of a series of modules in order to carry out all exercises and practical possibilities related to voltage instrument transformers. These modules are, for instance, the three-phase AC variable power supply, the network analyzer, the digital multimeter, the overcurrent time electronic relay, the variable resistor and the three-phase voltage transformer modules.
