Overvoltage and Surge Arrester Monitoring
SMA01 Surge and Lightning Monitoring device
SMA01 is an electromechanical measuring device developed for monitoring lightning protection equipment such as Metal Oxide Arresters (MOA), SPDs (Surge Protection Devices), and TLAs (Transmission Line Arresters). It is connected in series to the grounding lead to measure total leakage current in the 0–50 mA range and detects and records lightning impulses starting from 200 A.
Thanks to its compact design, it can be easily mounted on the bottom, top, back, or using clamps. With its stainless steel and aluminum body, and IP67 protection class, it is suitable for outdoor conditions. It self-generates its power during measurement, requires no battery, and is maintenance-free.
Manufactured in accordance with the IEC 62561 standard, the SMA01 is a reliable, durable, and practical solution for field applications.
