Kumwell Integrated online smart SPD is the patent product and is able to detect microamps leakage current of SPD in the real time.it can detect itself status, collect data automatically and report actively. Integrated smart SPD adopts standard RS485 and it can beapplied in the power distribution of railway, airport, electricity, petrochemicals, new energy, communication etc.
Characteristics :
• CT sensor make it possible to detect 1µA level of SPD pure resistance leakage current
• Adopting reverse insertion technology and sophisticated mathematical model to gain real leakge current
• Built-in sensor to detect lightning peak current, polarity, number and time
• Monitoring lightning protection module status to judge it is normal or abnormal
• Monitoring SPD external disconnector status
• Monitoring operating voltage and ambient temperature
• Flexible network, convenient for network monitoring and alarm within seconds
• Integrated small structure, no need to secondary wiring
