GB/Z 18039.2-2000Electromagneticcompatibility - Environment - Assessment of the emission levels in the power supply of industrial plants as regards low-frequency conducted disturbances (English PDF)

1 Foreword

GB/Z 18039.2-2000 was issued by SAMR; SAC on 3 April 2000 and has been in force since 3 April 2000.

It is one of 5 parts of the GB/Z 18039 series.

2 Scope

This standard is a Chinese national guiding technical document on electromagnetic compatibility, dealing with the environment and with the assessment of emission levels in the power supply of industrial plants as regards low-frequency conducted disturbances. It describes the procedures for assessing the disturbance emitted into the supply by the installations, equipment and systems put into an industrial environment connected to the public network, and the level of low-frequency conducted disturbance to be allowed there; from that basis the corresponding emission limits can be derived. It is written for alternating current low-voltage non-public networks at 50/60 Hz, and it does not cover shipboard, aircraft, railway or offshore platform networks. The text is an identical adoption of IEC 61000-2-6:1996 and quotes GB/T 4365-1995, GB 17625.2-1999 and GB/Z 17625.3-2000.
