Introduction

The purpose of this standard is to establish a basic test specifications to assess industrial machinery and electrical equipment when subjected to voltage dips and short interruption Performance changes. This standard rated input current and low voltage power supply network connection does not exceed 16A per phase electrical industrial machinery, electronic equipment and The basic requirements for the test system voltage dips and short interruption immunity, configuration and test equipment, test methods and procedures and with different environments and Installation states associated test level. The reference to the standards GB 5226.1-2002/60204-1 IEC .2000 "Part 1 Safety of machinery - Electrical equipment Score. General technical conditions ", GB/T 21067-2007" industrial machinery and electrical equipment Electromagnetic compatibility - Generic immunity requirements "and other standards. Industrial machinery and electrical equipment voltage sag And short interruptions immunity test specification

1 Scope

3 Terms and Definitions

And the following terms and definitions GB/T 4365-2003 established apply to this standard. 3.1 Apparatus, equipment or system performance with the proper performance of undesired deviation. [GB/T 4365-2003, the definition 161-01-19] Note. The "decrease" The term can be used for temporary or permanent failure failure. 3.2 At some point the voltage on the electrical system suddenly reduced to below the predetermined threshold, then returned through a brief interval to normal. [GB/T 17626.11-2008, the definition 3.3] NOTE. Voltage sag is a two-dimensional electromagnetic interference, which is determined by the voltage level and time (duration). 3.3 A point on the power supply system to a sudden drop in all phases of the interrupt predetermined threshold or less, then subjected to a brief interval to restore normal ......
