Note 1 to entry: Under sinusoidal conditions, the non-active power is the absolute value of the reactive power Q or the imaginary part of the complex power S _ MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdi9qqqj=hEeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meaabaGacmGadiWaaiWabaabaiaafaaake aadaadaaqaaiaadofaaaaaaa@3A75@ , thus Q =|Q|=| Im S _ | MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaieYdi9WrpeeC0lXdi9qqqj=hEeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meaabaGacmGadiWaaiWabaabaiaafaaake aacaWGrbWaaSbaaSqaaGWaaiab=XJi+bqabaGccqGH9aqpdaabdaqa aiaadgfaaiaawEa7caGLiWoacqGH9aqpdaabdaqaaiGacYgacaGGTb WaaWaaaeaacaWGtbaaaaGaay5bSlaawIa7aaaa@47F6@ .

Note 2 to entry: The coherent SI unit for non-active power is voltampere, VA. The special name "var" and its symbol "var" are also used. See 131-11-45.
