此处显示最低线对线电压额定值的101至150%系统仍然存在范围：跳闸仍然存在、阻塞仍然存在、无跳闸和无阻塞警报、469未正确插入如果469机箱仅部分与机箱接合，则1秒钟后出现此维修警报。固定底盘手柄，以确保所有触点正确匹配469 NOT IN SERVICE模拟模式范围：未编程、模拟模式、输出继电器强制、模拟输出强制、测试开关短路RTD#1高报警：135°C范围：1至250°C。此处将显示其他电压参数的类似高报警。如果没有为S2 SYSTEM SETUP（S2系统设置）\VOLTAGE SENSING\VT connection type（电压传感）设置点编程VT连接类型，则尝试输入这组消息时，将出现以下闪烁消息。5.3.4速度如果转速计功能分配给一个数字输入，则可在此处查看转速计读数。如果在S3 digital INPUTS\ASSIGNABLE INPUT1/2/3/4中没有数字输入配置为转速表，则尝试输入这组信息时，将显示以下闪烁信息。❙ 电压计量❙ [输入]更多Vab:0 Vbc:0 Vca:0 V范围：0至20000 V如果VT连接编程为无平均线路电压：0 V范围：1至20000 V，则不可见如果VT连接被编程为无Van：0 Vbn:0 Vcn:0伏范围：0到20000 V，仅当VT 5.3 A2计量数据5实际值5 5.3.5功率计量功率计量和3相总功率量的值显示在此处。在这里也可以看到瓦图尔和瓦时。按照惯例，感应电机消耗瓦和瓦（+瓦和+瓦）。同步电机可以产生vars（–vars）并将其反馈给电力系统。如果S2 SYSTEM SETUP（S2系统设置）\ VOLTAGE SENSING（电压传感）\ VOLUMENT TRANSFORMER RATIO（电压互感器比率）设定点未编程，则尝试输入这组信息时会出现以下闪烁信息。实际功率（hp）直接从实际功率（kW）转换而来。此仅显示值不用于保护功能。无论计量的实际功率是多少，此消息显示的功率都不会超过65535 hp。5.3.6扭矩报警消息此消息出现在报警状态事件记录中（如果功率（+瓦和+瓦）。反映模拟输入名称为编程的模拟输入3-4 0百分比范围：–5100至4900%消息，仅当模拟输入差分3-4设置为%Diff消息反映模拟输入名为编程的Analog 3-4 0单位范围：–100000至100000消息，仅在模拟输入差分线3-4设置为Abs Diff消息反映模拟输入名称已编程。此功能未编程。输入ESCAPE♥，下一页的表格可用于确定VT和CT是否处于正确相位，以及它们的极性是否正确。不正确接线引起的问题是极高的不平衡水平（CT）或错误的功率读数（CT和VT）或相位反转跳闸（VT）。要纠正接线，只需启动电机并记录相量。使用下表以及记录的相量、系统旋转、VT连接类型和电机功率因数，可以确定正确的相量。注意，Va的相位角（如果为δ，则为Vab）总是
101 to 150% of Rated Value of lowest line-to-line voltage is shown here SYSTEM Still Present Range: Trip Still Present, Block Still Present, No Trips & No Blocks ALARM, 469 NOT INSERTED PROPERLY If the 469 chassis is only partially engaged with the case, this service alarm appears after 1 sec. Secure the chassis handle to ensure that all contacts mate properly 469 NOT IN SERVICE Simulation Mode Range: Not Programmed, Simulation Mode, Output Relays Forced, Analog Output Forced, Test Switch Shorted RTD #1 HI ALARM: 135°C Range: 1 to 250°C. Similar Hi Alarms will occur for other voltage parameters will be displayed here. If no VT connection type is programmed for the S2 SYSTEM SETUP \ VOLTAGE SENSING \ VT CONNECTION TYPE setpoint, the following flash message will appear when an attempt is made to enter this group of messages. 5.3.4 SPEED If the Tachometer function is assigned to one of the digital inputs, the tachometer readout may be viewed here. If no digital input is configured as tachometer in S3 DIGITAL INPUTS \ ASSIGNABLE INPUT1/2/3/4, the following flash message will appear when an attempt is made to enter this group of messages. ❙ VOLTAGE METERING ❙ [ENTER] for more Vab: 0 Vbc: 0 Vca: 0 Volts Range: 0 to 20000 V Not seen if VT Connection is programmed as None AVERAGE LINE VOLTAGE: 0 Volts Range: 0 to 20000 V Not seen if VT Connection is programmed as None Van: 0 Vbn: 0 Vcn: 0 Volts Range: 0 to 20000 V Seen only if VT 5.3 A2 METERING DATA 5 ACTUAL VALUES 5 5.3.5 POWER METERING The values for power metering and 3-phase total power quantities are displayed here. Watthours and varhours can also be seen here. An induction motor by convention consumes Watts and vars (+Watts and +vars). A synchronous motor can generate vars (–vars) and feed them back to the power system. If the S2 SYSTEM SETUP \ VOLTAGE SENSING \ VOLTAGE TRANSFORMER RATIO setpoint is not programmed, the following flash message appears when an attempt is made to enter this group of messages. Real Power (hp) is converted directly from Real Power (kW). This display-only value is not used for protection functions. This message will not display more than 65535 hp regardless of the actual kW that are being metered. 5.3.6 TORQUE ALARM MESSAGE This message appears in the Alarm Status Event Record (if power (+Watts and +vars). reflects Analog Input Name as programmed ANALOG 3-4 0 Percent Range: –5100 to 4900% Message seen only if Analog In Diff 3-4 set to %Diff Message reflects Analog Input Name as programmed ANALOG 3-4 0 Units Range: –100000 to 100000 Message seen only if Analog In Diff 3-4 set to Abs Diff Message reflects Analog Input Name as programmed THIS FEATURE NOT PROGRAMMED ENTER ESCAPE ð ð MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE MESSAGE ESCAPE GE Power Management 469 Motor Management Relay 5-15 5 ACTUAL VALUES 5.3 A2 METERING DATA 5 5.3.9 PHASORS To aid in wiring, the tables on the following page can be used to determine if VTs and CTs are on the correct phases and that their polarity is correct. 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
