Qualitrol GIII Thermometer (Star Product)

The AKM345 GEN3 OTIWTITM is a future‑ready oil‑and winding‑temperature indicator launched by Qualitrol, suitable for transformers of all ratings. Building on the robust bellows‑based measurement technology of previous generations, the AKM345 GEN3 also introduces new features and standard options that support transformer digitalization, meeting all technical specification requirements. With a completely redesigned and enhanced architecture, the AKM345 GEN3 is more rugged and reliable, and comes standard with an IP66 protection rating and a C5 high‑corrosion‑resistance class.

Fiber-optic temperature sensor

Fiber-optic temperature measurement employs the internationally recognized state-of-the-art GaAs (gallium arsenide) sensor technology. By embedding fiber-optic sensors directly within the windings, multi-point temperature monitoring is enabled, providing more effective, long-term, and precise surveillance of winding hotspot temperatures in transformers. This allows for real-time, reliable acquisition of the true internal winding temperatures, facilitating comprehensive insight into the transformer's operating condition, extending its service life, and enhancing both load capacity and production efficiency.

Transformer Intelligent Integrated Online Monitoring Platform QTMS

The QTMS Transformer Smart Monitor, an integrated smart platform for multi-site and multi‑asset condition monitoring in power grid systems, leverages microprocessor technology and advanced digital signal processing to accurately assess the health and performance of oil‑filled transformers. This monitoring system can track more than 120 parameters and consolidates all transformer‑related data into a single comprehensive platform, enabling big‑data analytics and supporting intelligent transformer monitoring.
