Introduction

Monitoring transformer temperature is a critical aspect of ensuring the longevity and efficient operation of transformers. Effective temperature management helps prevent failures, optimize performance, and extend service life. This article delves into the methods and parameters critical for effective temperature monitoring, highlighting solutions provided by Guanshan Instruments Company.

Importance of Monitoring Transformer Temperature

Transformer temperature monitoring is vital to prevent overheating, which can lead to insulation degradation, winding damage, and ultimately transformer failure. Maintaining optimal temperatures ensures operational efficiency and reduces maintenance costs.

Methods of Temperature Monitoring

Various methods are employed to monitor transformer temperature, each providing distinct advantages. Common techniques include:

• Thermal Imaging Cameras
• Embedded Temperature Sensors
• Infrared Thermography
• Fiber Optic Sensors

Each method has its specific application depending on the transformer type and operating environment.

Parameters for Temperature Monitoring

Key parameters for effective transformer temperature monitoring include:

Oil Temperature

Oil temperature indicates the overall thermal health of a transformer. Though operating temperatures vary, it's generally recommended for oil temperatures to remain below 90°C for extended periods. Sudden spikes in oil temperature may indicate potential issues such as overloading or internal faults.

Winding Temperature

Winding temperature is crucial because it generally runs hotter than oil. While a normal winding temperature might be around 105°C, any sustained temperature over 120°C could suggest deterioration. Critical temperature alarms should be set to trigger if winding temperatures approach 130°C to 140°C.
