Instruments designed and developed
by the hearts and minds of utility
electricians around the world
Vanguard Instruments Company, (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 fi rst VIC product was a computerized circuitbreaker analyzer,
which was a resounding success. It became the forerunner of an entire
series of circuitbreaker test equipment. Since its beginning, VIC’s
product line has expanded to include microcomputer-based, precision
micro-ohmmeters, single and three phase transformer winding turns-
ratio testers, transformer winding-resistance meters, mega-ohm
resistance meters, and a variety of other electrical utility maintenance
support products.
VIC’s performance-oriented products are well suited for the utility
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 procedural steps is
eliminated. Every VIC instrument is competitively priced and is
covered by a liberal warranty.
