Independent Surge Counter: PH312-065

Independent Surge Counter detects lightning surges using a current sensor and records within the built-in memory the peak current value, the current polarity, and the time.
The data can be retrieved collectively by PC.
Additional unit: PH312-066 transfers relay contact output signal as optical signal.
Then, it is converted to contact signal at receiver.

Current sensor unit
1) Split core current transformer (can be installed on existing cables)
2) Rogowski coil (can be installed at the bottom of existing towers)
