LRU

* All affected LRUs are disconnected

2. Connect ArcSafe MET3. Setup and run test4. Identify location of arc

5. Locate precise breach area

Using the ARCSAFE tools independently:

• Use the MET to roughly locate a breach– Visually inspect the suspect area– Using repeat mode, listen and look for

the discharge

• Use the IFP to manually scan a section of wiring

Supports Arc Fault Circuit Breakers

• ARCSAFE® can be effectively used to validate and/or locate indicated faults by virtue of Arc Fault Circuit Breaker trip

• Immediately aids in determination of nuisance circuit breaker trips

Is ARCSAFE® MEHV safe?

• Yes! MEHV is safe!– Micro-energy high-voltage is similar to static electricity– Energy is typically in the micro-joules range

• Will not damage insulation after repeated use• No injury from physical contact• Static sensitive areas:

– Connection to static sensitive electronics and use inpresence of flammable vapor is not recommended

Comparison: HiPot vs. ARCSAFE®

• ARCSAFE®: – Higher voltage (Up to 4500V)– Lower energy (typically < 300µJ)– No damage to wiring

• HiPot:– High voltage (Up to 2000V)– High current (> 5mA)– Failures result in wiring damage

Comparison: TDR vs. ARCSAFE®

• ARCSAFE®:– Locates insulation breaches– Does not locate shorts and opens– Requires minimal training

• TDR:– Locates shorts and opens– Does not effectively locate insulation breaches– Requires extensive training and analysis beyond

locating opens and shorts

VERY effective tools when used in combination

Combined with TDR, ARCSAFE® can identify and locate most wiring failures including:

• Shorts and Opens• Damaged insulation that can result

in an arc fault

SUMMARY

ARCSAFE® provides a proactive approach to

identifying degraded or damaged wire insulation that

is at risk of arc faults
