What is a winding sensor?

A winding sensor is a temperature sensor specifically designed to be embedded in or installed near the windings of electrical equipment such as transformers, generators, and motors. Its main function is to provide accurate, real-time measurement of winding temperatures to help operators monitor equipment health and prevent failures due to overheating.

Why are winding sensors important?

• Prevent insulation damage caused by excessive temperatures.
• Enable predictive maintenance and reduce downtime.
• Improve operational safety by detecting abnormal conditions early.
• Extend the lifespan of critical electrical assets.

Types of winding sensors

• Resistance Temperature Detectors (RTDs): Widely used, accurate, but sensitive to electromagnetic interference.
• Thermistors: Cost-effective, fast response, but limited temperature range.
• Thermocouples: Good for high temperatures, but require calibration and can drift over time.
• Fiber Optic Winding Sensors: Immune to electromagnetic interference, suitable for high-voltage environments, and offer precise, real-time measurements.
• Fluorescence Fiber Optic Sensors: The latest and most advanced, offering unmatched accuracy, response speed, and safety, especially in harsh or high-voltage environments.

Advantages of fluorescence fiber optic winding sensors

• Immunity to EMI: Not affected by electromagnetic interference, making them ideal for power transformers and generators.
• High voltage safety: No metal parts or electrical signals, ensuring absolute safety even in the most demanding environments.
• Long-term stability: No drift, reliable accuracy over years of service.
• Fast response: Real-time monitoring of rapid temperature changes.
• Compact and robust: Easy to embed within windings during manufacturing or retrofitting.

Main applications of winding sensors

• Power transformers: Continuous monitoring of winding hot spots to prevent insulation aging and failures.
• Generators: Accurate temperature profiling for windings in hydro, thermal, and nuclear power stations.
• Motors: Industrial motors, traction motors, and large drives benefit from improved reliability and safety.
• Reactors and chokes: Ensuring safe operation in power electronics and grid infrastructure.

How to choose the right winding sensor

• Consider measurement accuracy and response time.
• Check compatibility with your monitoring system (analog/digital output, protocol, आदि।).
• Assess installation requirements (new build or retrofit, space constraints, आदि।).
• Evaluate long-term stability and maintenance needs.
• For harsh or high-voltage environments, prioritize fluorescence fiber optic sensors.
