Understanding the dangers of arc flash

The effects of an arcing fault can be devastating. The intense thermal energy can cause severe burns in a fraction of a second.

One of the major causes of electrical burns and deaths to workers is ignition of non-fire rated clothing due to an arcing fault. A victim may never return to work or enjoy quality of life. Treatment costs can exceed $1,000,000 per case.

Other considerations include loss of life, potential litigation fees, loss of process, and potential fines.

Avoiding calibration in an energized enclosure is the best way to avoid arc flash when working with current sensors. Senva offers two models--Autoset and Preset—which both address this application issue. 

Autoset^tm self-calibrates after installation using Senva’s 24sense^tm technology which adapts to system changes, such as air balancing.

Preset^tm uses a unique, patent pending, scaled adjustment which is set to the motor FLA.  It is priced comparably  to manually adjusted sensors, but saves up to $30 per point, because there is no need to return to the site to calibrate.
