  • TD_MRF3_08.03_GB 3

    1 Introduction and application The MRF3 is a universal frequency relay and contains the protective functions required by most electrical utili-ties for mains parallel operation of power stations: Four elements for over- or under frequency protection Two elements for frequency gradient supervision

    df/dt Fast decoupling of the generator from the grid at

    mains failure Suitable for load shedding systems

    2 Features and characteristics Microprocessor technology with watchdog effective active low pass filter for suppressing of

    harmonics, four elements for frequency supervision, alternatively

    for under- or overfrequency detection, adjustable reconnection values for the frequency

    stages independent separate adjustable timers, adjustable voltage threshold for blocking and dis-

    connection of the frequency measurement, reclaim time of output relays after the frequency has

    been exceeded or fallen short of., display of all measuring values and setting parame-

    ters for normal operation and tripping via an alpha-numerical display and LEDs,

    display of actual measuring values, storage and dis-play of tripping values,

    minimum- and maximum measurement of the fre-quency gradient,

    adjustable tripping window for the df/dt supervision at mains decoupling application,

    the protective functions can be assigned individually to the output relays (relay matrix),

    display of measuring values as primary quantities, storage and display of tripping values in a fault

    memory (voltage-failure safe), recording of up to eight fault occurences with time

    stamp in the fault recorder, External triggering of the fault recorder Recording of external functions as digital track in the

    fault recorder* for blocking the individual functions by the external

    blocking input, parameters can be set according to requirement,

    safe and fast mains decoupling by df/dt supervi-sion,

    suppression of indication after an activation (LED flash),

    display
