AEL-CTFP Применение основ трансформатора тока для устройств защиты

The Current Transformer Fundaments Application for Protections Devices, "AEL-CTFP", has been designed by Edibon to demonstrate the students which the main functions of current transformers are and which the parameters that must be considered in order to choose the adequate current transformer are.

This trainer allows the students to check the transformation ratio and how it changes if the load variates. With this trainer, the student will study the zero residual current, the rated overcurrent factor, how change the current ratio error in function of the load and how work the current transformers.

The AEL-CTFP consists of a series of modules in order to carry out all exercises and practical possibilities related to current 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 current transformer modules.
