ScopeThis

31、standard applies to surge-protective devices designed for application on the low-voltage ac supplymains (1000 V rms and less, frequency between 48 Hz and 62 Hz). Low-voltage surge-protective devices(secondary arresters) are intended to be connected at locations between, and including, the secondary

32、termi-nals of the distribution transformer and the main service entrance panel. Surge-protective devices limit tran-sient overvoltages by diverting surge current and subsequently automatically interrupting the passage offollow current.2.
