Why Monitor Transformer Windings
Monitoraggio della temperatura degli avvolgimenti del trasformatore is a critical component for safe operation of modern power systems. As the core equipment of power systems, abnormal temperature changes in transformer windings directly affect equipment safety and grid stability.
Winding overheating is the most common cause of transformer failures, accounting for over 60% of total transformer faults. Quando temperatura dell'avvolgimento exceeds rated values, it accelerates insulation material aging, reduces dielectric strength, and ultimately leads to insulation breakdown and equipment damage. Statistics show that for every 8°C increase in insulation temperature, its service life is halved.
Implementazione monitoraggio della temperatura degli avvolgimenti has the following important significance: preventing equipment overheating damage, extending equipment service life, improving power supply reliability, riducendo i costi di manutenzione, abilitante manutenzione predittiva, garantendo la sicurezza del personale, e riducendo le perdite economiche. Through continuous monitoring of winding temperature changes, operation and maintenance personnel can detect abnormal conditions in time and take appropriate measures to prevent major accidents.
