Circle diagram constant air-gap induction motor images shown here, where, The circle diagram is drawn using the data obtained from no load and either short circuit or, in case of machines, blocked rotor tests by fitting a half-circle in points O and A. Beyond the error inherent in the constant air-gap assumption, the circle diagram introduces errors due to rotor reactance and rotor resistance variations caused by magnetic saturation and rotor frequency over the range from no-load to operating speed. Steinmetz equivalent circuit Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the
Capital Hill, Australian Capital Territory of that capital city, Melbourne Avenue, Adelaide Avenue, Perth Avenue, Hobart Avenue and Darwin Avenue with Brisbane Avenue, Sydney Avenue not even being close. The streets which surround the hill in concentric circles are named after increasing spheres of influence with the inner-most circle called Parliament drive and then spanning out to Capital Circle, State Circle, National Circuit, Dominion Circuit and Empire Circuit. When Griffin drew up his plans in 1912, there was still some optimism that New Zealand might join the Federation of Australia. Griffin's plans included eight avenues radiating out from Capital Hill named after the capitals of
