Circle diagram Circle diagram First conceived by A. Heyland in 1894 and B.A. Behrend in 1895, the circle diagram is the graphical representation of the performance of the electrical machine drawn in terms of the locus of the machine's input voltage and current. The circle diagram can be drawn for alternators, synchronous motors, transformers, induction motors. The Heyland diagram is an approximate representation of circle diagram applied to induction motors, which assumes that stator input voltage, rotor resistance and rotor reactance are constant and stator resistance and core loss are zero. Another common circle diagram form is as described in the two
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
