29、 and measurement techniques - Voltage dips, short interruptions and voltage variations on d.c. input power port immunity tests 1 Scope and object This part of IEC 61000 defines test methods for immunity to voltage dips, short interruptions and voltage variations at the d.c. input power port of elect
30、rical or electronic equipment. This standard is applicable to low voltage d.c. power ports of equipment supplied by external d.c. networks. The object of this standard is to establish a common and reproducible basis for testing electrical and electronic equipment when subjected to voltage dips, shor
31、t interruptions or voltage variations on d.c. input power ports. a This standard defines: - the range of test levels; - the test generator; - the test Set-up; - the test procedure. The test described hereinafter applies to electrical and electronic equipment and systems. It also applies to modules o
32、r subsystems whenever the EUT (equipment under test) rated power is greater than the test generator capacity specified in clause 6. The ripple at the d.c. input power port is not included in the scope of this part of IEC 61000. It is covered by IEC 61 000-4-1 71) This standard does not specify the t
33、ests to be applied to particular apparatus or systems. Its main aim is to give a general basic reference to IEC product committees. These product committees (or users and manufacturers of equipment) remain responsible for the appropriate choice of the tests and the severity level to be applied to th

38、he definitions of IEC 60050(161) and the following definitions and terms apply. 3.1 EUT equipment under test 3.2 immunity (to a disturbance) the ability of a device, equipment or system to perform without degradation in the presence of an electromagnetic disturbance IEV 161-01-20 3.3 voltage dip a s
39、udden reduction of the voltage at a point in the low voltage d.c. distribution system, followed by voltage recovery after a short period of time, from a few milliseconds up to a few seconds IEV 161-08-10, modified 3.4 short interruption the disappearance of the supply voltage at a point of the low v
40、oltage d.c. distributed system for a period of time typically not exceeding 1 min. In practice, a dip with amplitude at least 80 YO of the rated voltage may be considered as an interruption. 3.5 voltage variation a gradual change of the supply voltage to a higher or lower value than the rated voltag
41、e. The duration of the change can be short or long. o 3.6 malfunction the termination of the ability of an equipment to carry out intended functions, or the execution of unintended functions by the equipment. O BSI 07-2001 a 4 General The operation of electrical or electronic equipment may be affect
42、ed by voltage dips, short interruptions or voltage variations of the power supply. Voltage dips and short interruptions are mainly caused by faults in the d.c. distribution system, or by sudden large changes of load. Is also possible for two or more consecutive dips or interruptions to occur. Faults
43、 in the d.c. distribution system may inject transient overvoltages into the distribution network; this particular phenomenon is not covered by this standard. Page 7 EN 61000-4-292000 Voltage interruptions are primarily caused by the switching of mechanical relays when changing from one source to ano
44、ther (e.9. from generator set to battery). During a short interruption, the d.c. supply network may present either a “high impedance“ or “low impedance“ condition. The first condition can be due to switching from one source to another; the second condition can be due to the clearing of an overload o
45、r fault condition on the supply bus. The latter can cause reverse current (negative peak inrush current) from the load. a These phenomena are random in nature and can be characterised in terms of the deviation from the rated voltage, and duration. Voltage dips and short interruptions are not always
46、abrupt. The primary cause of voltage variations is the discharging and recharging of battery systems; however they are also created when there are significant changes to the load condition of the d.c. network. 5 Test levels The rated voltage for the equipment (UT) shall be used, as a reference for t
47、he specification of the voltage test level. The following shall be applied for equipment with a rated voltage range: - if the voltage range does not exceed 20 % of its own lower limit, a single voltage from the range may be used as a basis for test level specification (UT); - in all other cases, the
48、 test procedure shall be applied for both the lower and upper limits of the rated voltage range. a The following voltage test levels (in % UT) are used: - O %, corresponding to interruptions; - 40 % and 70 %, corresponding to 60 % and 30 % dips; - 80 % and 120 %, corresponding to I20 % variations. T
49、he change of the voltage is abrupt, in the range of ps (see generator specification in clause 6). The preferred test levels and durations are given in tables la, 1 b and IC. The levels and durations shall be selected by the product committee. 0 BSI 07-2001 Page 8 EN 61000-4-29:2000 Test The test conditions of “high impedance” and “low impedance” reported in table 1 b refer to the output impedance of the test generator as seen by the EUT during the voltage interruption; additional information is given in the definition of the test generator and test proce
