    20 ms average establishes the value of the peak of the fault,  TRIDENT 3U3I archives the mean values over 1sec of the 3 voltages and the 3 currents at the instant of the beginning of the fault. These values will be memorized as the values preceding the fault, when the fault is finished and recorded.

  • Page 31: Calculation Of Slow Variations

    Additionally, after the end of the fault, TRIDENT archives the mean values over 1s of the 3 voltages and the 3 currents following the end of the fault. If it is an interruption, TRIDENT defines its type as long or brief according to its duration with reference to the programmed discrimination threshold.

  • Page 32: Calculation Of The Frequency

    Every second the rolling mean value over 10 seconds of the frequency is calculated. To do this TRIDENT continuously detects zero crossings of the voltage on the phase V1, totalises the number of these zero crossings and calculates their mean over 10 secs.

    5.4.8 Calculation of voltage imbalances (TRIDENT 3U3V) The rate of imbalance measured by TRIDENT 3U3V is, classically, equal to the ratio of the RMS values of the inverse and direct components. The rate of unbalance that is commonly used is defined by the ratio |Vi|/|Vd |, modulus of the inverse component over the modulus of the direct component.

From these values, it calculates the amplitudes of the 40 first harmonics on voltages (simple or line) and currents every second, as well as the THDs and instantaneous TDDs for each phase. These measurements are then integrated over the period configured by the user in order to obtain the mean values.
