Since breaker performance can be tested while the breaker is still on-line and in service,
Vanguard Instruments Company Inc.cks breaker operation while it's
on line ("hot")
Trip/Close-coil Current monitoring allows
"Fingerprint" analysis while breaker is in service
Senses current changes at bushing CT
Test Shots can be down loaded to an IBM pc
(Analysis software included)
Stores up to 30 shots in an EEPROM
Verifies breaker performance by "overlaying"
timing shot against a baseline
Since breaker performance can be tested while the breaker is still on-line and in service, down-time maintenance losses from testing are eliminated.
