What is a winding sensor?

A Wicklungssensor is a temperature sensor specifically designed to be embedded in or installed near the windings of electrical equipment such as transformers, Generatoren, und Motoren. 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

• Widerstandstemperaturdetektoren (RTDs): Weit verbreitet, genau, but sensitive to electromagnetic interference.
• Thermistoren: Kostengünstig, schnelle Reaktion, but limited temperature range.
• Thermoelemente: Good for high temperatures, but require calibration and can drift over time.
• Fiber Optic Winding Sensors: Immun gegen elektromagnetische Störungen, Geeignet für Hochspannungsumgebungen, and offer precise, real-time measurements.
• Fluoreszenzfaseroptische Sensoren: The latest and most advanced, bietet unübertroffene Genauigkeit, Reaktionsgeschwindigkeit, und Sicherheit, especially in harsh or high-voltage environments.

Advantages of fluorescence fiber optic winding sensors

FAQs about winding sensors

What is the best type of winding sensor for high voltage transformers?

Fluorescence fiber optic winding sensors are the best choice due to their immunity to EMI and absolute electrical isolation.

How many winding sensors are recommended for a transformer?

Typischerweise, 3–6 sensors (one for each winding phase and neutral) are used to monitor hot spots in large power transformers.

Can winding sensors be retrofitted to existing equipment?

Ja, many fiber optic solutions are designed for retrofit installations, but best results are achieved when sensors are embedded during manufacturing.

What is the typical accuracy of fluorescence fiber optic winding sensors?

Industry-leading products offer ±1°C or better accuracy, with long-term drift less than 0.1°C/year.
