Best Instrument to Measure Input Current Surge—Oscilloscope vs Data Logger vs Clamp Meter

Hi All,

Would like to measure input current surge on system.Which is best instrument to measure.

Clamp on current meter not able to capture the surge.

Any suggestion.

Thanks

Hi Ankim,

Are you familiar with UPC Test Manager software and UPC Controllers? Try to read it in here… http://www.pacificpower.com/Resources/Documents/DS4PEACKCURRENT092012.pdf

I've learned from one of the seminars I've attended that Fiber Optic Current Sensors (FOCS) has been tested to measure the surge current which flows through copper conductor. Try to read about it here. http://www.daedalus.ei.tum.de/attachments/art...55/SENSOR_CONF_fiber_optic_current_sensor.pdf

Finally, have you tried to use Fluke Clamp Meter. It has a great "inrush" feature. Check it here… https://www.youtube.com/watch?v=aRJMNqffdlc


Hope it somehow helps. :)

Hi Sardiah,

Thank you

The methods of voltage measurement used are the resistance potentiometer, capacity potentiometer, and sphere gap. The potentiometers serve as dividers of the high-surge voltages for measurement at the cathode-ray oscillograph. The resistance potentiometer is a fundamental standard, but requires consideration of its limitations for very rapid phenomena. In cases where these can be compensated for or are negligible, the resistance potentiometer method is very desirable. The capacity potentiometer is a secondary standard which can be calibrated.
