在标准IEC-61000 中关于电压变化特性的定义为:
voltage change characteristic, ΔU(t)
the time function of the r.m.s. voltage change evaluated as a single value for each successive half period between zero-crossings of the source voltage between time intervals in which the voltage is in a steady-state condition for at least 1 s.
这段话我看了半天没有看明白,这是在说什么呢?
观看示意图的话
是不是说 ΔU(t)= ΔU(t1)- ΔU(t2),即两个稳态电压的间隔内,任意两10ms内的电压有效值之差?
