PTI-P4 transformer optical fiber temperature measurement online monitoring system monitors the temperature of transformer winding and oil, analyzes and evaluates its aging procedure and insulation status, and gives early warning of risks.
This device is specially designed for power applications, and is very suitable for measuring the temperature of hot spots on the back of transformers. It is a new type of transformer internal temperature monitoring device that can directly, real-time and accurately measure the temperature of windings and other hot spots, and can achieve comprehensive monitoring of the transformer interior. In addition to wide temperature measurement range, accurate and reliable temperature measurement performance, it also has excellent EMI/RFI (electromagnetic interference/radio frequency interference) characteristics, high voltage insulation and anti-interference performance.
