Problems arising from incorrect wiring are extremely high unbalance levels (CTs) or erroneous power readings (CTs and VTs) or phase reversal trips (VTs). To correct wiring, simply start the motor and record the phasors. Using the tables below along with recorded phasors, system rotation, VT connection type, and motor power factor the correct phasors can be determined. Note that the phase angle for Va (Vab if delta) is always assumed to be 0° and is the reference for all angle measurements. Common problems include: Phase currents 180° from proper location (CT polarity reversed) Phase currents or voltages 120 or 240° out (CT/VT on wrong phase) n PHASORS n [ENTER] for more Va PHASOR 0.0% AT 0°Lag Vb PHASOR 0.0% AT 0°Lag Vc PHASOR 0.0% AT 0°Lag Ia PHASOR 0.0% AT 0°Lag Ib PHASOR 0.0% AT 0°Lag Ic PHASOR 0.0% AT 0°Lag ENTER ESCAPE e e MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Multilin 469 Motor Management Relay 5-15 5 ACTUAL VALUES 5.3 A2 METERING DATA 5 Table 5–1: THREE-PHASE WYE VT CONNECTION ABC Rotation 72.5° = 0.3 pf lag 45° = 0.7 pf lag 0° = 1.00 LEARNED DATA 5 ACTUAL VALUES 5 5.4A3 LEARNED DATA 5.4.1 MOTOR STARTING PATH: ACTUAL VALUES ?× A3 LEARNED DATA ? MOTOR STARTING The 469 learns the acceleration time, the starting current, as well as, the thermal capacity required during motor starts. This data is accumulated based on the last five starts. The 469 also keeps statistics for last acceleration time, last starting current, and last starting capacity. This information can be reset to default using the S1 469 SETUP ?× INSTALLATION ?× RESET MOTOR INFORMATION setpoint. If motor load during starting is relatively consistent, the LEARNED ACCELERATION TIME may be used to fine tune the acceleration protection. Learned acceleration time will be the longest time of the last five successful starts. The time is measured from the transition of motor current from zero to greater than overload pickup, until line current falls below the overload pickup level. LEARNED STARTING CURRENT is measured 200 ms after the transition of motor current from zero to greater than overload pickup. This should ensure that the measured current is symmetrical. The value displayed is the average of the last 5 successful starts. If there are less than 5 starts, 0s will be averaged in for the full 5 starts. The LEARNED STARTING CAPACITY is used to determine if there is enough thermal capacity to permit a start (refer to Section 4.8.2: Start Inhibit on page 4–48 for more information on start inhibit). If there is not enough thermal capacity for a start, a start inhibit will be issued.
