Industrial Test Transformers
In industrial manufacturing, the job is not done until the
product passes the test. Global manufacturers of items
such as pumps, drives, and generators build products for
use in many different electrical systems, which requires
testing of operation at both 50 and 60 Hz and a
multitude of voltage combinations.
A configurable transformer is an essential component
of their test lab. High reliability means less factory
downtime and reduces revenue losses due to downtime.
Each manufacturer will have unique requirements. PCT’s
engineering team will work closely with you to determine
the voltages, phasing, and switching capability you need
to provide the Right Transformer for the job.
