  • Page 14: Intended Use

    Safety instructions 2.3 Intended use The multifunctional voltage monitoring relay VMD461 monitors frequencies, undervoltages and overvoltages in DC, AC and 3(N)AC systems. The phase voltages and/or line-to-line voltages are measured as r.m.s. value and are con- tinuously shown on the device display. The measured value required to trig- ger the alarm relay is stored.

  • Page 18 Function Vector shift Vector shift detection is triggered by a sudden phase displacement (vector shift). Unbalance The unbalance is calculated between the phase voltages (in conformity with IEEE) and the line-to-line voltages (in conformity with NEMA). The higher of the two values will be compared to the specified response value. Phase sequence When phase sequence monitoring is enabled, an alarm is triggered in 3(N)AC systems as soon as the phase sequence no longer matches the specified value.
