How must the two secondary coils of a 460/115/230-volt, single-phase transformer be connected to obtain 460/115 volts?
What will be an ideal response?
To obtain 460/115 volts, the two secondary coils must be connected in parallel. The polarity of each coil must be correct before making this connection. The parallel connection of two coils of opposite polarity results in a short circuit and internal damage to the transformer.
