The autotransformer article could benefit from having two drawings side by side, one showing a normal transformer and the other an autotransformer.

See Autotransformer # Limitations where it says what could appear on the low voltage tap if there were an open circuit in the turns it covers.
23.
The line-interactive UPS is similar in operation to a standby UPS, but with the addition of a multi-tap variable-voltage autotransformer.
24.
A large three-phase autotransformer may have a " buried " delta winding, not connected to the outside of the tank, to absorb some harmonic currents.
25.
It sounds like you need an Autotransformer to step up the voltage, just like Interact " ) " 09 : 51, 22 May 2007 ( UTC)
26.
This may also be performed by a " buck boost transformer " which is distinct from an autotransformer, since the former may be wired to provide galvanic isolation.
27.
The transient is of a very short duration, less than 5 microseconds and occurs when the motor current from the secondary of the autotransformer is forced to the line voltage.
28.
The autotransformer architecture was retained, but the source of power changed from the Metro-North New Haven Line system to the Con Edison-supplied Van Nest Substation ( ).
29.
Reactance-type tap changers, when operating in oil, must allow for the additional inductive transients generated by the autotransformer and commonly include a vacuum bottle contact in parallel with the diverter switch.
30.
Depending on the design, changing the autotransformer tap can cause a very brief output power disruption, which may cause UPSs equipped with a power-loss alarm to " chirp " for a moment.
