If the power input varies throughout the operating cycle and the maximum value of the power input exceeds, by a factor greater than two the arithmetic mean value of the power input occurring during a representative period., then the power input is the maximum value that is exceeded for more than 10 % of the representative period. Otherwise the power input is taken as the arithmetic mean value.# G$ ~( G9 C, K. k3 d' ^: a

简单地说就是,如果某个功率在10%工作周期以内都出现,而该值又大于工作周期内功率的算术均方根的2倍,则这个功率就是输入功率,否则就是算术均方根是功率。, H! D! H: V/ J# I) [
