The OTI WTI Temperature Indicator is a key device that is used in transformers to track the temperature and protect against excessive heat. Temperatures that are measured with OTI WTI indicators are essential in maintaining transformer reliability, safety, productivity, and a reliable future operation.
In industrial and utility applications, the deployment of a functioning OTI WTI temperature indicator for transformers decreases the probability of failure, or trouble-free operation.
What is an OTI WTI Temperature Indicator?
An OTI WTI Temperature Indicator consists of two major components:
Together the system provides comprehensive monitoring of the transformer temperature.
The Working Principles of the OTI WTI Temperature Indicator
The OTI (Oil Temperature Indicator)
The OTI portion of the OTI WTI temperature indicator system uses a temperature sensing bulb placed within the oil of the transformer to measure oil temperature. As temperature increases, the amount of oil in the sensing bulb expands causing the reading of the temperature on the OTI dial to correspondingly reflect the increased expansion.
The WTI (Winding Temperature Indicator)
The WTI portion of the OTI WTI temperature indicative system utilizes both oil temperature sensing and electrical current input to simulate the temperature of the actual windings of the transformer and show an accurate temperature reading.
Difference in OTI WTI Temperature Indicator Functions
Although both are part of the same OTI WTI temperature indicator system, their roles differ:
Feature | OTI Function | WTI Function |
Measures | Oil temperature | Winding temperature |
Method | Direct sensing | Simulation method |
Purpose | Cooling monitoring | Core protection |
Understanding this difference helps in selecting the right OTI WTI temperature indicator for transformers.
