  • Page 23 1MRS755972 Voltage Relay REU 610 Technical Reference Manual - ANSI Version The high-set overvoltage element 59P-2 can be set to be based on either Conventional voltage measurement (59P-2 mode selected), or Calculated negative phase-sequence voltage (47 mode selected). The selection between these modes is made either by using HMI or parameter S7, the default setting being conventional measurement.
  • Page 24 REU 610 Voltage Relay 1MRS755972 Technical Reference Manual - ANSI Version When the conventional protection mode is selected and the phase-to-phase voltages exceed the set pickup value of the high-set element, 59P-2, the element generates a pickup signal after a ~ 50 ms’ pickup time. When the set operate time at definite-time characteristic or the calculated operate time at IDMT characteristic elapses, the element generates a trip signal.

    1MRS755972 Voltage Relay REU 610 Technical Reference Manual - ANSI Version 5.1.4.3. Undervoltage protection The undervoltage protection can be based on either conventional voltage measurement or the calculated positive phase-sequence voltage. The low-set undervoltage element 27P-1 is based on conventional voltage measurement.
  • Page 26 REU 610 Voltage Relay 1MRS755972 Technical Reference Manual - ANSI Version Element 27P-1 has a settable resetting time (both at definite-time and IDMT characteristics), 27P-1 RESET, for reset coordination with existing electromechanical relays or for reducing fault clearance times of recurring, transient faults.

  • Page 27: Residual Overvoltage Protection
