1. A method for monitoring a condition of a turbine bucket, comprising the steps of:
- inserting a temperature sensor into a turbine;
measuring at least one temperature of the turbine bucket; and
comparing the measured temperature to a temperature of a reference turbine bucket to determine the condition of the bucket.

Abstract
A method for determining oxidation in turbine buckets allows for conditional based maintenance of the turbine buckets. The method includes measuring a temperature of a turbine bucket and comparing the measured temperature to a temperature of a reference turbine bucket to determine the condition of the bucket. The method provides useful temperature data to determine if the turbine should be stopped and the bucket serviced. This method may be used in place of interval based maintenance to increase bucket life, reduce bucket failure, and increase turbine operating time.
