Abstract

A corrosion monitoring system includes one or more objects coupled to respective portions of a transformer tank. The one or more objects are configured to corrode before the respective portions of the transformer tank. At least one optical sensor is coupled to each of the objects. The at least one optical sensor has an optical output that changes in response to strain of the object. An analyzer is coupled to the at least one optical sensor. The analyzer is configured to perform one or more of detecting and predicting corrosion of the transformer tank based on the output of the at least one optical sensor.

Dependent claims

A corrosion monitoring system, comprising:

one or more objects coupled to respective portions of a transformer tank, the one or more objects configured to corrode before the respective portions of the transformer tank;
at least one optical sensor coupled to each of the objects, the at least one optical sensor having an optical output that changes in response to strain of the object;
and
at least one additional optical sensor having an optical output that changes in response to a temperature of the object and is not sensitive to strain;
and
an analyzer coupled to the at least one optical sensor, the analyzer configured to perform one or more of detecting and predicting corrosion of the transformer tank by subtracting the output of one of the at least one additional sensors from the output of one of the at least one optical sensors.
