NOTE 4 It is recommended that the resistance of windings at the end of the test be determined by taking x. N1 q& O& \7 {# q2 W( I/ i
resistance measurements as soon as possible after switching off and then at short intervals so that a curve of

公司和三方认证公司一般都是测试完毕,立即测试的电阻为温升电阻。未按推荐的方法进行绘制计算温升电阻。# x8 P' F, M- o: @
