Recommended spacings are for guidance only. User needs to set appropriate values to
assure performance for: high potential test; impulse test; high humidity; partial discharge;
high altitude; and other considerations like configuration.
The circle diagram can be used to predict the performance of a transformer for various
loads and power factors. A convenient scale of volt amperes is shown on the unity power
factor line (u.p.f.) and commences at the zero or no-load locus. To use the diagram, measure
the known V.A. and scribe an arc about the “zero” locus of a length that contains the angle
of the burden power factor. The point at which the arc terminates is the error locus in phase
angle minutes and ratio correction factor.
