Description: The Electrical Circuit and Network Trainer is a versatile and comprehensive training system designed for engineering university labs to facilitate the study of electrical circuits and networks. It includes both AC and variable DC power sources with capabilities for single-phase and three-phase experiments, supporting a range of loads including resistive, inductive, and capacitive elements. The system enables the study of fundamental electrical laws and theorems such as Ohm's Law, Kirchhoff's Laws, and various circuit theorems, as well as the measurement of resonant frequency, Q-factor, and power factor of different circuit configurations. With its ability to simulate balanced and unbalanced loads in star and delta connections, this trainer provides hands-on experience in analyzing circuit behavior, enhancing students' practical understanding of complex electrical networks.
