How to Solve the Problem of Capacitor Temperature Rise

Capacitor temperature may rise too high due to long running time, improper capacitor selection, poor ventilation, medium aging, or increasing dielectric loss (Tan δ). Capacitor temperature rise will affect the life of the capacitor and eventually lead to capacitor damage. How to solve this problem? 1. The ambient temperature of the capacitor should be strictly … Read more
