Under Voltage & Over Voltage Relay Testing System
Under Voltage & Over Voltage Relay Testing System
Product Code : 46618
Brand Name : Tesca
Product Description

46618 Under Voltage & Over Voltage Relay Training System is intended for advanced practical training in protective devices regarding transmission lines, cables and network sections in power systems lab. A Relay is an electrically operated switch use 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. 46618 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 system 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.
