Littelfuse Webinar, "Preventing Arc Flash through Resistance Grounding," Explains How to Modify Electrical Systems to Significantly Reduce Arc Flash Events

CHICAGO - (BUSINESS WIRE) - Littelfuse, Inc. (NASDAQ:LFUS), in partnership with Plant Engineering magazine, will offer a complimentary web-based seminar titled "Preventing Arc Flash through Resistance Grounding," on December 2, 2009 at 2 pm Eastern Time (11 am PST/1 pm CST). This webcast will offer practical tips for reducing hazardous conditions, such as Arc Flash and ground faults, with minimal interruption to plant operations (click here to register for the Littelfuse Arc Flash webinar).

Who can benefit from the Arc Flash prevention webinar?

• Plant managers

• Electrical maintenance managers

• Electrical system designers

• Electrical contractors with industrial clients

• Plant electrical safety managers

• Anyone concerned with reducing Arc Flash and plant downtime

Attendees of the webinar will learn how to:

• Identify hazardous conditions caused by ground faults

• Reduce Arc Flash Hazards significantly with resistance grounding

• Convert their solidly grounded or ungrounded system to one resistance grounded

• Find and eliminate electrical faults while keeping their plant running

About Arc Flash Prevention

Current trends show that plant electrical workers and power system designers are taking a new look at different strategies to prevent Arc Flash. Long used in mines, petrochemical plants, and other heavy industrial plants, resistance grounding is now winning converts in general industry. This systemic approach is proven to eliminate phase-to-ground Arc Flash incidents from forming anywhere in the system.

If the neutral point of the transformer connects to earth ground via a power resistor, then the resistance limits phase-to-ground current to just a few amps, not enough to cause downtime by tripping the overcurrent protection device, and not enough to allow an Arc Flash Hazard to occur. Most Arc Flash events, even phase-to-phase, begin as ground faults. As a result, this approach can eliminate 95 percent of all Arc Flash incidents, according to IEEE.

Registration Information

"Preventing Arc Flash through Resistance Grounding" will be broadcast on December 2, 2009 at 2 pm Eastern Time (11 am PST/1 pm CST).
