OTI Gauge vs Transformer Winding Temperature Indicator
An OTI gauge is used for transformer oil temperature indication and control. It monitors the transformer oil temperature and supports cooling control and alarm output.
A transformer winding temperature indicator is different. It is used to indicate simulated winding temperature based on transformer top oil temperature and load-current-related thermal simulation. In transformer temperature monitoring projects, OTI and WTI gauges are often selected according to different monitoring purposes.
