FAQs About Fenarro's High Voltage Fuses & Surge Arresters
Q Do you provide monitoring systems for surge arresters?
AYes, we offer online monitoring systems that provide real-time status information and predictive maintenance alerts.
Q Can your fuses be used for transformer inrush current protection?
AYes, our transformer protection fuses are designed to withstand transformer inrush currents while providing fast protection against fault conditions.
Q How often should surge arresters be replaced?
ASurge arresters should be monitored regularly and replaced when the monitoring indicators show degradation, typically after 10-15 years or after major surge events.
Q What is the difference between current-limiting and expulsion fuses?
ACurrent-limiting fuses interrupt current before it reaches peak value, while expulsion fuses use gas generation to extinguish arcs. Current-limiting fuses provide better protection for transformers.
