Abstract
In accordance with at least one aspect of this disclosure, a system can include a primary coil wound around a moveable magnetic core, at least one secondary coil wound in one continuous direction and magnetically coupled with the primary coil, and a controller operatively connected to determine a position of the moveable magnetic core and configured to detect a fault across the secondary coil.

A system, comprising:
- a primary coil wound around a moveable magnetic core;
- at least one secondary coil wound around the moveable magnetic core in one continuous direction and magnetically coupled with the primary coil;
- and
- a controller operatively connected to determine a position of the moveable magnetic core and configured to detect a fault across the secondary coil.

A method, comprising:
- detecting a fault in at least one secondary winding of a variable differential transformer across a first side line with respect to a center-tap and a second side line with respect to the center-tap using a sum voltage of the first side line and the second side line;
- and
- outputting a fault detection signal to a user indicting the fault.
