GB/T 17625.7-2013 Translated English of Chinese Standard. (GBT 17625.7-2013, GB/T17625.7-2013, GBT17625.7-2013): Electromagnetic compatibility - Limits - Limitation of voltage changes, voltage fluctuations and flicker in public low-voltage supply systems for equipment with rated current <= 75 A and subject to conditional connection [Buy--download True-PDF in 3-second: https://play.google.com/books > Sign in > This BOOK > "3-dots" > Export > Save as "*.pdf"]https://www.chinesestandard.net, 26 ott 2018 - 16 pagine This Part is concerned with the emission of voltage changes, voltage fluctuations and flicker produced by equipment and impressed on the public low-voltage supply system. This Part specifies the limits of voltage changes produced by equipment tested under specified conditions. This Part is primarily applicable to electrical and electronic equipment having a rated input current from 16 A up to and including 75 A, which is intended to be connected to public low-voltage distribution systems having nominal system voltages of 220 V, line-to-neutral at 50 Hz, and which is subject to conditional connection. |
