SMTE181 Relay Protection And Automation Electric Power Systems Trainer Electrical Lab Equipment Educational Equipment Teaching Equipment1. Equipment introduction
1.1 Overview
In the context of rapid economic development, the demand for stable power supply is getting higher and higher. During the operation of the power supply lines of the power grid, unpredictable faults often occur in the power supply lines. These faults are various, which may be disconnection faults or short-term faults caused by plants and animals around the power grid. Different faults have different solutions. Choosing the right solution saves time and money.
In the SMTE181 relay protection and automated power system trainer, the equipment provides a variety of experiments to simulate faults, which can help users understand various fault response plans and automation solutions.
