Scope of application
STREAMER SMA is an electro-mechanical leakage measurement device and surge counter. The leakage meter provide the value of the total leakage current flowing through the ground conductor from 0 to 50 mA. The surge counter is meant to count the number of lightning strikes based on the current flowing in a conductor.
The SMA shall be installed in series on the ground leads, at the ground terminal of the metal surge arrester. It can be mounted top, bottom or strapped. Terminals can be used either way. The device complies to the IEC 62561. Thanks to its IP67, housing, rugged materials and self power, the SMA is suitable for outdoor and hazardous atmospheres.
