Right Size Your Transformer | T&D World the general shape of the load-cycle curve is essential to knowing the loading effect on the distribution transformer. Loads with a very high demand but a very low hours-use number may be served more effectively with a smaller transformer than loads of the same kVA demand with higher hours-use loads.

FaceTime - general discussion - iPhone: use in hospitals – yes most hospitals still have the signs up – but they are pretty much a relic of old analogue phones. These days phones go everywhere and on – and most of the staff use them to communicate – much easier than pagers. As far as open WiFi. Just remember the ad is a US ad.
