A Winding Temperature Indicator (WTI) is a crucial device in power transformers that estimates and displays the "hot-spot" temperature of the windings, using a heating element fed by the transformer's load current to simulate actual heat, protecting the insulation from damaging overheating and triggering alarms or shutdowns. It features current and maximum temperature pointers on a dial, with adjustable contacts for control functions, and uses a sensor bulb in the oil to sense temperature change

Power Transformer Winding Temperature Indicator (WTI) | LRM & Trip Setting | Protection Explained. In this video, we explain the operation and setting of the Winding Temperature Indicator (WTI) used in power transformers. You will learn how LRM (Local Remote Alarm) is set at 105°C and Trip setting at 110°C, and how the trip command operates through the relay to trip the circuit breaker for transformer protection. #PowerTransformer #WindingTemperatureIndicator #WTI #TransformerProtection #tripset
