Ground Fault Protection

From Leach International
 

 
The wear and tear of wiring harnesses can create a safety issue in commercial aircraft, particularly in the aging ones.However, an approved and proven technology exists that can detect and isolate the electrical faults, which can otherwise escape the harness and create hazardous situations in the aircrafts fuel tanks.
