Abstract
A circuit for monitoring the health of the transformers is disclosed. In an implementation, the circuit includes a transformer that provides an input signal and a pulse generator that generates a pulse signal. An analog-to-digital converter receives a combined signal that includes the input signal and the pulse signal, and the analog-to-digital converter converts the combined signal to a digital representation of the combined signal. The circuit includes a first digital filter and a second digital filter that are connected to the analog-to-digital converter. The first digital filter reconstructs an amplitude characteristic of the input signal, and the second digital filter reconstructs the pulse signal. The circuit also includes a controller that indicates a short circuit or an open circuit associated with the transformer based upon a value of the reconstructed pulse signal.
