PGTI's First Trip Tests streamlines electrical maintenance and provides more data per cycle and better information about breaker mechanics and how quickly breakers open the first time

The Windows 7 platform for First Trip Testing uses a high speed USB accelerometer to measure the mechanical movements of circuit breakers. 

The good news about the Windows 7 platform First Trip Tests:

  • True measurement for low voltage circuit breakers and how fast the breaker trips the first time!
  • Get more mechanical information by just opening and closing breakers.  
  • No need to remove breaker from the cubicle
  • Quick setup with no electrical connections required
  • Outages take seconds instead of minutes/hours
  • Good for when you don't have time for extensive testing 
  • Great between maintenance cycle outage testing

Why Even Test Breakers Anyway?  

There is a 30% chance of a breaker not opening if it has been closed (and not tested) for 3 years or more. And after 7 years or more, there is about a 50/50% chance that the breaker will not open like it should. Chances for a non-tested breaker opening after 8 to 10 years decreases dramatically. If a breaker doesn't clear in 5 cycles as it should, Arc Flash hazard escalates. For example, situations that might normally be Cat 2 could easily become a Cat 4, leaving the worker in charge under-protected and at much greater risk of injury.

How else can First Trip testing help me?

With the new platform, we can also determine (on some breaker models) whether a vacuum bottle has begun to lose vacuum, without having to remove the breaker from the cell! This data is very beneficial when determining if a breaker will trip the very first time.
