Product Description
Lightning Current Counter (LCC) is used to count the number of
discharging lighting current of various lightning protection
device. The LCC extends the count number up to 99 times from one
digit to two digits. The LCC is installed to the lighting current
discharging module, for example, connect the LCC to the earthing
line of the surge protection device (SPD), starting from minimum
current of 1kA (8/20 s) to maximum current of 150kA (8/20 s). The
recorded data can be kept for one month when the power is cut off.
The LCC works with Current Mutual Inductor (CMI). The coil of the
CMI is connected to the PE line of the SPD. The two wires of the
CMI are connected to the 5th and 6th terminals of the LCC. When the
surge happens, the SPD discharges the lighting current to the
ground and the CMI inducts the lightning current. The lighting
current samples will be taken to the LCC and processed by the
inside integrated circuit, displaying the count number on the LED
when pressing the button on the LED tube. There are six terminals
on the LCC. The 1st and 2nd terminals are used to supply the power.
The 3rd and 4th terminals can be short circuit so reset the count
to zero. The 5th and 6th terminals are used to connect the two
wires of the CMI.
Digital Lightning Strike counter will record direct lightning strikes to an external lightning protection system.
