    The "Limit Volt" system for monitoring the regulated distance in a HV transformer.

    Main functions:

    • Monitoring the regulated line voltage (under- and overvoltage)
    • Monitoring and blocking of switching commands from the voltage regulator if the voltage is outside of the permitted range
    • Return to desired tap position of the tap changer
    • Activation of the voltage regulator high-speed return
    • Display of all measured values
    • Adaption of the behavior of the device to individual needs by using adjustable parameters
