Product Description
Three Phase Over Current & Earth fault Numeric Relay Testing System is a useful product for Electrical Power System Laboratories. The main purpose of protection relay is to detect and identify faults and interrupts power to the equipment to avoid the entire network to fail or cause more damages to personnel or equipment. An Over Current Relay operates when the load current exceeds a preset value, whereas the function of Earth Fault Relay is to protect any system from earth fault.
Three Phase Over Current & Earth fault Numeric Relay Testing System includes inbuilt Microcontroller based Three Phase Over Current and Earth Fault Numerical Relay with facilities to select various characteristic curves at different Time Multiplier Settings (TMS) and Current Settings. The setting and selection of characteristic curves are carried out by a soft touch keypad provided on the front panel of the Numeric Relay. There is a large font LCD to display all necessary parameters in a single frame.
Three Phase Over Current & Earth fault Numeric Relay Testing System also provides facility to inject and adjust the current to analyze the Numerical Relay at different current values. All the requisite protective devices such as MCB, Fuses, etc. have been used for utmost safety.
Three Phase Over Current & Earth Fault Numeric Relay Testing System is an ideal platform to enhance education, training, skills & development amongs our young minds.
