Models PT Models PTW5-1-110 & PTW5-2-110 Recommended Minimum Spacings A = Unit to Unit or to Ground = 1.25” minimum. B = HV to Ground in air = 6.50” 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. (a) Two fuse transformers should not be used for Y connections. It is preferred practice to connect one lead from each voltage transformer directly to the neutral terminal, using a fuse in the line side...
