    MTR-4 Installation Instructions Connection Settings of connections must reflect actual state; otherwise measurements are not valid. Connection When connection is selected, load connection and the supported measurements are defined (see chapter 6, “Measurements” regarding connection mode, on page 24). Setting of current and voltage ratios Before setting current and voltage ratios, it is necessary to be familiar with the conditions in which the device is to be used.

    MTR-4 Installation Instructions Explanation of basic concepts Sample factor − M A meter measures all primary quantities with sample frequency which cannot exceed a certain number of samples in a time period. Based on these limitations (65 Hz·128 samples), a sample factor is calculated.

  • Page 27: Present Values

    MTR-4 Installation Instructions Present values All values are calculated as an average of number of periods set in general settings/average interval. Voltage The instrument measures true RMS values of all phase voltages (U1, U2, U3), connected to the transducer. Phase-to-phase voltages (U12, U23, U31), average phase voltage (Uf) and average phase-to-phase voltage (Ua) are calculated from measured phase voltages (U1, U2, U3).
  • Page 28 MTR-4 Installation Instructions Power factor and power angle Power factor is calculated as quotient of active and apparent power for each phase separately (cosϕ , cosϕ , cosϕ ) and total power angle (cosϕ ). For correct display of PF via analogue output and application of the alarm, ePF (extended Power Factor) is applied.
