每次测试前必须重置任何跳闸。在每次过载曲线测试之前，立即短接紧急重启终端，以确保使用的热容量为零。否则会缩短行程时间。注入适当振幅的电流，以获得所示值，并验证跳闸时间。电机负载可在：A2计量数据\电流计量3中查看。使用的热容量和预计跳闸时间可参见：A1 STATUS \ MOTOR STATUS。无功和视在功率规格为Iavg<2×CT时√3×2×CT×VT×VT满量程的±1%。执行以下步骤以验证准确性。1.更改以下设置点：S2系统设置\电流传感\相位CT初级：1000 S2系统设置/电压传感\ VT连接类型：Y型S2系统设置|电压传感\电压互感器比率：10.00:1 2。按照下表注入电流并施加电压。验证测量值的准确性。查看测量值：A2 METERING DATA\ POWER METERING

Any trip must be reset prior to each test. Short the emergency restart terminals momentarily immediately prior to each overload curve test to ensure that the thermal capacity used is zero. Failure to do so will result in shorter trip times. Inject the current of the proper amplitude to obtain the values as shown and verify the trip times. Motor load may be viewed in: A2 METERING DATA\CURRENT METERING 3. Thermal capacity used and estimated time to trip may be viewed in: A1 STATUS\MOTOR STATUS The specification for reactive and apparent power is ±1% of √3 ×2 × CT × VT × VT full scale at Iavg <2 × CT. Perform the steps below to verify accuracy. 1. Alter the following setpoints: S2 SYSTEM SETUP\CURRENT SENSING\PHASE CT PRIMARY: 1000 S2 SYSTEM SETUP\VOLTAGE SENSING\VT CONNECTION TYPE: Wye S2 SYSTEM SETUP\VOLTAGE SENSING\VOLTAGE TRANSFORMER RATIO: 10.00:1 2. Inject current and apply voltage as per the table below. Verify accuracy of the measured values. View the measured values in: A2 METERING DATA\POWER METERING
