Order No.: GT2023061201
Specification:
This system has been designed to enable students to connect and apply a wide range of electric, electronic protection relays with circuits of increasing complexity, besides verifying their characteristics.
The training program is developed on interchangeable modules that enable to assemble the circuits with the mere connection of the modules via flexible leads of the equipment.
The modules are wholly made of insulating material, the graphic representation with international electric symbols and the educational safety terminals enable to assemble and test electric circuits in short time.
 
Main subjects dealt with:
• Study of the operational characteristics of protection relays.
• Typical applications of protection relays.
• Identify cation number of the protection function.
• Combination of more relays to attain specification protection goals.
