Circle Diagram Recommended Minimum Spacings A = Unit to Unit = 0.75” minimum. B = HV to Ground in air = 3.00” minimum. Recommended spacing 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-ampere is shown on the unity power factor line (u.p.f) and commences at the zero or no-load locus. To...
