JB/T 10821-2008Voltage reduction and three-phase balancing power saving devices for low-voltage AC systems (English PDF)

JB/T 10821-2008 is the English-translated version of 低压交流降压及三相平衡系统节电装置.

JB/T 10821-2008 is a recommended Chinese machinery industry standard for the devices that reduce voltage and balance the three phases in low-voltage AC systems in order to save energy. For these units it fixes the terms and definitions, the classification, the electrical and mechanical performance requirements together with the matching test methods, the inspection rules, and the provisions on signs, packaging, transport and storage. It applies to units whose rated working voltage is AC 1000 V and below, whose frequency is 50 Hz or 60 Hz and whose rated capacity is 3000 kVA and below. It quotes GB 4208, GB 7251.1-2005 and JB/T 8750-1998. Its classifications are K36 and ICS 29.120.
