27、reporting the more generally applicable and acceptabletests of polyphase induction motors and generators. Many of the tests described may be applied to bothmotors and generators, as needed, and no attempt is made to partition the test procedure into clauses andsubclauses that separately apply to mot
28、ors or to generators. Whenever the term motoris used, it is to beunderstood that it may be replaced by the term generator, if applicable. Likewise, whenever machineisused, it may be replaced by either motoror generator,if applicable. Since polyphase power systems arealmost universally three-phase sy
29、stems, the equations in this standard have been written specifically forthree phases. When the test is performed on other than three-phase power, the equations shall be modifiedappropriately.1.2 PurposeInstructions for conducting and reporting the more generally applicable and acceptable tests are c
30、overed todetermine the performance and characteristics of polyphase induction motors and generators. Additionaltests, not specified herein, may be required to satisfy specific research or application needs. These proce-dures shall not be interpreted as requiring the performing of any specific test i
31、n a given transaction.2. ReferencesThis standard shall be used in conjunction with the following standards.

General 3.1 Power Supply3.1.1 SelectionBecause the performance of an induction machine is dependent not only upon the value of the line voltageand frequency but also on the wave
35、shape and the balance in magnitude and phase angle of the line voltages,correct data can be obtained only by careful measurement with accurate instrumentation and by employing asuitable source of power.3.1.2 WaveformThe power supply shall provide balanced voltages closely approaching a sinusoidal wa
36、veform. The har-monic distortion coefficient, THD, shall not exceed 0.05. The THD is defined as shown in Equation (1).(1)whereE1is the root-mean-square value of the fundamental of the voltage wave, in volts (V), Eis the total root-mean-square value of the voltage wave, in V.3.1.3 Voltage unbalanceTh
37、e voltage unbalance shall not exceed 0.5%. The percent voltage unbalance equals 100 times the maximumvoltage deviation from the average voltage divided by the average voltage.Example: With line voltages of 220 V, 215 V, and 210 V, the average voltage is 215 V, the maximum devi-ation from the average
38、 is 5, and the unbalance equals (100 5)/215 = 2.3%.3.1.4 FrequencyFor general testing, the frequency shall be within 0.5% of the value required for the test being conducted,unless otherwise specified. Any departure from the specified frequency during the test directly affects theefficiency obtained
39、with Efficiency Test Methods A, B, and B1. When these Methods are used, the fre-quency shall be within 0.1% of the specified test value. 3IEEE Std 119-1974 has been withdrawn; however, copies can be obtained from Global Engineering, 15 Inverness Way East, Engle-wood, CO 80112-5704, USA, tel.

All rights reserved.3Rapid changes in frequency cannot be tolerated during testing because such variations affect not only themachine being tested, but also the output measuring devices. Variations in frequency during a
41、 test shall notexceed 0.33% of the average frequency.3.2 Types of tests3.2.1 TypicalPolyphase induction machines are normally given a routine test, but they may also be given additional tests. For machine tests included in a typical routine test, refer to NEMA MG 1-2003 B74parts 12 and 20.A typical
42、form for reporting routine test data is shown in Annex B. A typical form for reporting additionaltest data is shown in Annex C. 3.2.2 Preliminary tests The measurement of the winding resistance is commonly the first test performed. The resistance or the con-tinuity of all windings and circuits shoul
43、d be measured at this time. The ambient temperature is measured using the procedure of IEEE Std 119-1974. If the machine has embed-ded detectors, these may be used to confirm that the winding is at the ambient temperature.3.2.3 Idle running testsRunning tests without load are made for the determinat
44、ion of core loss and windage and friction losses.Some other tests such as shaft voltage may also be performed under these conditions.3.2.4 Tests with loadTests with load are made for the determination of efficiency, power factor, speed, current, and temperaturerise. Some of the miscellaneous tests o
45、utlined in Clause 8 are also made with load. For all tests with load, themachine shall be properly aligned and securely fastened. For readings to be used in performance determina-tions, the machine temperature rise shall be some value between 50% and 120% of the rated temperaturerise. The usual proc
46、edure is to take readings at higher loads first and then follow with readings at lowerloads.3.2.5 Tests with rotor lockedIt should be recognized that the testing of induction machines under locked-rotor conditions with polyphasepower involves high mechanical stresses and high rates of heating. There
47、fore, it is necessary thata) The mechanical means of securing the machine and locking the rotor are of adequate strength to pre-vent possible injury to personnel or damage to equipment.b) The direction of rotation is established prior to the test.c) The machine is at approximately ambient temperatur
48、e before the test is started.The current and torque readings shall be taken as quickly as possible, and, to obtain representative values,the machine temperature should not exceed rated temperature rise plus 40 C. The readings for any pointshall be taken within 5 seconds after voltage is applied.4The
