I suggest that an arc is something continuous and producing light or illumination. A spark is something abrupt and short lived.
Ralph McDiarmid, AScT Compliance Engineering Group Xantrex Technology Inc. From: Speakman, Jim [mailto:[email protected]] Sent: September 22, 2003 8:32 AM To: [email protected] Subject: Arcing & Sparking Fellow Listers At a recent equipment design review, a discussion on arcing and sparking indicated a lack of definitive knowledge of the difference between an 'arc' and a 'spark'. Is an 'arc', basically just a long 'spark'. If so, at what point (precisely) does a 'spark' become an 'arc'? Have I got it all wrong? Are they 'something else'. Can anyone enlighten my darkness? __________________________ Jim Speakman (Design Safety Representative (Southern Sites) Thales Defence Ltd Thales Sensors Manor Royal Crawley West Sussex RH10 9PZ > * Tel: +44(0)1293 644911 > * Mob: +44(0)7968 529439 > * Fax : +44(0)1293 644194 > * e-mail [email protected] > __________________________ This e-mail contains confidential information for the addressee only.
