Vanguard EZCT - Manual (Page 4)

Vanguard Instruments Company, Inc.
Vanguard Instruments Co., (VIC), was founded in 1991.
Currently, our 28,000 square-foot facility houses Administration,
Design & Engineering, and Manufacturing operations. From its
inception, VIC’s vision was, and is to develop and manufacture
innovative test equipment for use in testing substation EHV circuit
breakers and other electrical apparatus.
The first VIC product was a computerized circuit-breaker analyz-
er, which was a resounding success. It became the forerunner of
an entire series of circuit-breaker test equipment. Since its begin-
ning, VIC’s product line has expanded to include microcomput-
er-based, precision micro-ohmmeters, single and three-phase
transformer winding turns-ratio testers, winding-resistance
meters, transformer tap-changing controllers, megaohm resist-
ance meters, and a variety of other electrical utility mainte-
nance support products.
VIC’s performance-oriented products are well suited for the util-
ity industry. They are rugged, reliable, accurate, user friendly, and
most are computer controlled. Computer control, with innovative
programming, provides many automated testing functions. VIC’s
instruments eliminate tedious and time-consuming operations,
while providing fast, complex, test-result calculations. Errors are
reduced and the need to memorize long sequences of procedur-
al steps is eliminated. Every VIC instrument is competitively
priced and is covered by a liberal warranty.
