SEL-1 Power Transmission Lines Trainer Vocational Training Equipment Electrical Engineering Lab Equipment
Description
SEL-1 Power Transmission Lines Trainer Vocational Training Equipment Electrical Engineering Lab Equipment

The equipment reproduces two high voltage transmission lines with the possibility of varying the parameters. It enables to learn and test the characteristics and management of high voltage distribution networks, with small scale components.
TRAINING PROGRAM:
Training refers to the study of power transmission in mediumvoltage high-voltage networks and to the study of three-phase transformers.
Main subjects dealt with:
• Models of power transmission lines with concentrated parameters
• Voltage drop and losses in power transmission lines
• Types of line (copper, aluminium)
• Parallel of power transmission lines
• Ideal transformer, real transformer
• No load, load and short-circuit tests of transformers, effi ciency of a three-phase transformer
• Star, delta, zigzag connections and time index of three-phase transformers
• Protection devices of transformers
