    PCC8 - MV12 Report

    Uploaded by

    Abhishek Rajput
    The document is a test report for an MV12 under/over voltage relay. It details the testing of the relay's overvoltage and undervoltage settings of 440V and 390V, respectively, with 5 second delays. The relay was injected with voltages above and below these settings on different phases and its operating times were recorded, all within the expected 5 second timeframe. Initially the relay's dip switches were found to be incorrect, preventing it from operating as per the settings. After correcting this, the relay was tested and found to operate healthily with the proper settings.
