The TTR300 Series of three-phase transformer
turns ratio test sets are designed to
measure the turns ratio of power,
instrument, and distribution transformers in
a substation or manufacturing environment. A
rugged and robust design makes these
instruments well suited for use in a variety
of harsh environments. Our leads are
specially designed to provide the necessary
flexibility needed in cold weather.
The TTR300 Series are ideal for use by power
transformer manufacturers. Their unique
testing procedures and storage capability
allows an operator to set up and test
difficult three-phase transformers (with
multiple tap changers and bushing CTs) in a
fraction of the time than it used to take
with other TTRs. This test also includes a
pass/fail limit of individual ratios.
