Power Protection Trainer DL GTU 103.2-7
The Power Protection Trainer DL GTU 103.2-7 is an advanced educational laboratory system designed to provide practical training on electrical power system protection techniques and transmission line analysis. This trainer enables students and engineers to study the operation, monitoring, and protection of modern electrical power networks through hands-on experiments and real-time fault analysis.
The system focuses on the principles of voltage and current monitoring, relay protection, fault detection, and transmission line safety. It introduces learners to the operation of instrument transformers, under/over-voltage relays, over-current relays, earth-fault protection systems, and power circuit breakers used in industrial and utility power systems.
The trainer includes a realistic three-phase power transmission line model representing a 360 km, 380 kV overhead transmission line with a 1:1000 scale factor. Students can analyze line parameters such as resistance, inductance, mutual capacitance, and earth capacitance while understanding power transmission behavior under normal and fault conditions.
