Two-phase systems are still extremely common in all industrial areas.

When testing parallel connections, it is best to have the transformers ___.

A T-connection with the teaser transformer operates at a reduced flux and therefore operates with a reduced iron loss and at a higher efficiency than open delta transformers.

A T-connection maintains a balanced phase relation better than a(n) ___.

For two transformers wired in parallel, if the transformer impedances are unequal, the load divides between them in inverse proportion to their ___.

Variable transformers can have extremely low power losses with efficiencies as high as 98%.

A short in the secondary results in a high ___ in the secondary.

An autotransformer must be directly connected to the ___ phase conductors of a 3-phase, 4-wire system.

All transformers have losses in power transfer from ___.

A variable transformer is a transformer used to step down line current to make it easier to measure.
