Electric Charge Surge Counter: PH312-064


Electric Charge Surge Counter detects lightning surges using a current sensor and calculates the electric charge from current waveform. Waveform data is not stored.
The data is transferred to your office PC through RS232C. The data is the electric charge, peak current value, the current polarity and the time. Q = I x T, Max: 9,999coulomb

COMPONENTS:
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)
Wave analysis unit Amplifier/waveform sensing analysis unit is supplied. For measurements taken in the field, the unit is placed inside a waterproof plastic box.
Recording unit Display/operation/clock/data memory/communication port.
Optical fiber receives the data from waveform analysis unit.
Recording unit can also be placed in a waterproof plastic box.

FUNCTION:
Current range Requested Maximum Current measurement value is the factory default setting. Measurement resolution is 20 times better (up to 200kA Max. at Min. current 100A.)
Trigger level Can be set from 5% of Maximum current value (factory default setting)
Frequency range 0.1Hz`1MHz
Accuracy Within } 15%
Data resolution 8bit
Optical fiber Single mode
Maximum length 100 meters
Accuracy of time Accurate within }2minutes per month (no optional clock)
Number of data record 200
Data transfer RS232C (D-sub, 9-pin)
Communication software Microsoft Windows - HyperTerminal
Power supply
