Tolerance definition. Asymmetry is an indicator of the mains quality and it is defined as the absolute value of the maximum deviation among the mains voltages, divided by the nominal voltage of the 3-phase system. The definition changes according to the voltage reference: Tolerance is another indicator of the mains quality and it is definied as the absolute value of the maximum deviation of the mains voltages from the nominal voltage, divided by the nominal voltage of the 3-phase system. The definition changes according to the voltage reference: 1) in case of measuring phase-phase voltages: 1) in case of measuring phase-phase voltages: L3 L2 max |V NOM-VPH-N| = |V NOM-V'L3-N| max |V NOM-VPH-N| = |V NOM-V'L1-N| = |V NOM-V'L2-N| = |V NOM-V'L3-N| Y Example: phase-phase monitoring VDNOM = VL1-L3= VL2-L1= VL3-L2 L1 L1 L1' V'L2-L1 V'L1-L3 L1' V'L2-L1 L3 x 100 VL2-L1 VL1-L2 VNOM x 100 2) in case of measuring phase-neutral voltages: V NOM L2 max |DVPH-N| = 0 ASY = 0 max |VNOM - VPH-PH| max |V NOM - VPH-N| L2' L3' max |DVPH-N| = |V'L3-N-V'L2-N| Y 2 x 100 V'L3-N L3 Y V NOM N V'L2-N Y max |VPH-N| N' N Y VNOM 2) in case of measuring phase-neutral voltages: L1 L1' Y x 100 V NOM = VL1-N = VL2-N =VL3-N L1 Y max |VPH-PH| Example: phase-neutral monitoring VL3-L2 L3' L2 max |DVPH-PH| = |VL3-L2-V'L2-L1| L3 V'L3-L2 VL3-L2 L2' L2 max |DVPH-PN| = 0 ASY = 0 max |VDNOM-VPH-PH| = |VDNOM-V'L2-L1| max |VDNOM-VPH-N| = |VDNOM-V'L1-L3| = |VDNOM-V'L2-L1| = |VDNOM-V'L3-L2| Specifications are subject to change without notice (18.07.06) DPC01, PPC01 Mode of Operation (cont.) Connected to the 3 phases (and neutral) DPC01 and PPC01 operate when all 3 phases are present at the same time and the phase sequence is correct. It can be decided whether to monitor upper and lower voltage level of each phase or their asymmetry and tolerance. output relay releases after the set time period. Asymmetry and tolerance monitoring: if one or more phase-phase or phase-neutral voltage exceed the set levels the red LED starts flashing 2 Hz and the respective output relay releases after the set time period. Note: For both functions, if the phase sequence is wrong or one phase is lost, both output relays release immediately. Only 200 ms Voltage level monitoring: if one or more phase-phase or phase-neutral voltage exceed the upper set level or drop below the lower set level, the red LED starts flashing 2 Hz and the respective delay occurs. The failure is indicated by the red LED flashing 5 Hz during the alarm condition. Example 1 (Mains monitoring - over and under phase-phase voltage) The relay monitors over and under voltage, phase loss and correct phase sequence. DPC01 and PPC01 ensure correct starting and operating conditions. They monitor the voltage level, phase sequence (correct direction of the motor rotation) and asymmetry. Example 2 (Motor monitoring - starting and operating load -asymmetry and tolerance of phase-neutral voltage) Frequent failures are fuse blowing and incorrect voltage level. In case of fuse blowing the motor regenerates a voltage in the interrupted phase. The relay detects the failure and reacts due to excessive imbalance among the phases. Centre knobs: Setting of upper ( ) and lower ( ) level or setting of asymmetry (ASY) and tolerance ( ) on relative scale. Lower knobs: Setting of delay on alarm times (DELAY 1, DELAY 2) on absolute scale: 0.1 to 30 s. Function/Range/Level/Time Setting Adjust the input range setting the DIP-switches 3 and 4.
