29、ines on conventional and rectifier-fed supplies 1 Scope This part of IEC 60034 applies to d.c. machines rated 1 kW and above operating on rectifier-fed power supplies, d.c. buses or other d.c. sources. Standardized methods are provided for determining characteristic quantities for conventional and r
30、ectifier-fed d.c. machines. Excluded are d.c machines for specific applications. These methods supplement the requirements in IEC 60034-1 and IEC 60034-2-1. NOTE It is not intended that this standard should be interpreted as requiring the carrying out of any or all of the tests described therein on
31、any given machine. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、 current and voltage specific quantities (rectifier-fed) 4.1 General This test serves to determine the variation of the terminal voltage and armature current for rectifier-fed d.c. machines at rated conditions. 4.2 Current ripple The armature current ripple is best measured with an oscilloscope inco
38、rporating capability for reading both d.c. and a.c. values. An alternative method is to use a peak-to-peak reading BS EN 60034-19:2014 8 IEC 60034-19:2014 IEC 2014 voltmeter, reading the voltage drop across a non-inductive resistor in series with the armature circuit. 4.3 Voltage ripple The voltage
39、ripple may be measured using an oscilloscope, a suitable oscillograph or an electronic peak-to-peak indicating voltmeter in series with an appropriate blocking capacitor of sufficient size not to affect the a.c. readings. It should be noted that in measuring the peak-to-peak value, deviations from t
40、he main waveform due to high frequency spikes should be ignored. 4.4 Measurement of average values In the case of rectifier supply, the average d.c. values of armature voltage and current can be measured using permanent-magnet moving-coil type instruments, or other instruments including digital inst
41、rumentation known to provide true average readings. 4.5 Measurement of root-mean-square values Root-mean-square values can be measured using electrodynamometer type, moving-iron type, or other instruments including digital instrumentation known to provide true r.m.s. readings. AC instrumentation of
42、the type using rectifiers to sense only a portion of the voltage or current signal and instruments whose calibration is based on the assumption of a sinusoidal waveform shall not be used. Oscilloscope readings of the voltage and current signals are recommended. 4.6 Calculation of current and voltage
43、 ripple factors and form factor The current ripple factors and the form factor shall be calculated using the formulas of IEC 60034-1, with maximum, minimum, average and r.m.s. waveform values measured according to 4.2 to 4.5 of this part. The voltage ripple factor shall be calculated similar to the
44、current ripple factor. 5 Determination of the armature circuit inductance 5.1 Procedure performed before starting the tests It is recommended to measure the armature circuit inductance by applying a single phase 50 Hz or 60 Hz alternating current to the armature circuit terminals of the machine. The
45、 rotor shall be locked to prevent rotation. Normal carbon brushes can be used if the alternating current is limited to approximately 20 % of the current rating of the machine to avoid overheating of the brushes or of the commutator during the short tests. The brushes shall be completely in contact w
46、ith the commutator surface and inspected before the test is started and after the test is finished. In declaring values of inductance it shall be stated whether the value refers to the saturated or unsaturated condition. Measure and record the r.m.s. value of voltage U, current I, frequency f and th
47、e phase angle between voltage and current. The phase angle may be determined using suitable means such as an oscilloscope or a phasemeter, or by an indirect method, e.g. using a wattmeter. 5.2 Measurement of armature circuit inductance of shunt and compound-wound machines The armature circuit induct
48、ance of shunt and compound-wound machines is to be measured for both unsaturated and saturated conditions. BS EN 60034-19:2014IEC 60034-19:2014 IEC 2014 9 For the unsaturated test the shunt-field winding shall be short-circuited to avoid high voltages being induced in the winding. For the saturated
49、test the shunt field is excited as for rated operation from a d.c. power supply, having a current ripple not exceeding 6 %. 5.3 Measurement of armature circuit inductance of series-excited machine The test on a series-excited machine is to be done for the saturated condition only. This test shall be carried out with the series-field winding separately excited at rated current using a d.c. power supply having a current ripple factor not exceeding 6 %. The sa
