ASC A-ET19 Under Voltage Relay Trainer is intended for advanced practical training in protective devices connected with transmission lines, cables and network sections in power systems lab. A Relay is an electrically operated switch which uses an electromagnet to operate a switching mechanism mechanically. Relays protect the power distribution equipment against continuing voltage sags that are detrimental to motors, ballasts, etc.
A-ET19 provides theoretical and practical experience to students by controlling, monitoring, and analyzing
individual relay settings and tripping characteristics. This product provides detailed representation of power
transmission systems which helps the students to perform experiments with minimal supervision. It also includes built-in variable supply and fast response graphical LCD display which makes the measurement system very precise.
