Product Description
Applicable to a variety of lightning protection lightning counter device counts the number of lightning current discharge. Count the number of double-digit expansion of the past can only be a bit count function, up to 99 times. Lightning counter installed on the need to discharge lightning current of the lightning protection module, such as the surge protector grounding line, initial count of current 1kA (8/20μs), the highest count of current 150kA (8/20μs ). Lightning counter power to protect the data inside the power supply up to 1 month. Lightning counter is equipped with current transformers. Installation when the current transformer core set of the PE into the surge protector line frequency transformer coil two-line introduction of lightning counter 5,6 terminal, solid connection. There surge occurs, the surge protector lightning discharge flow, the induced lightning current transformer, coupled to the counter after sampling, the counters through the internal IC signal processing, after the thunder and lightning, in the LED digital tube display switch on the press , which shows that the number of lightning current discharge. Lightning current counter has six terminal, 1,2 two terminal then N, L lines for the counter to provide charging power supply; intermediate 3,4 2 terminal, the short counter then what can be achieved re-zero; 5,6 2 the introduction of a terminal current transformer coil two lines.
