Optional Transformer Load Tap Changer Control
Voltage regulator or LTC tap positions can be changed remotely using the optional Tap-Changer
Remote Control Box. This option eliminates the need to manually raise or lower tap positions
from the transformer control panel.
Internal Test Record Storage
Up to 1,000 test records can be stored in the TRF-100’s Flash EEPROM memory. Each test
record may contain up to 99 turns-ratio, excitation current, phase angle, and nameplate voltage
readings. Test records can be recalled locally or transferred to a PC via the USB interface.
Transformer Test Plans
The TRF-100 can store up to 128 transformer test-plans in its Flash EEPROM. A test plan is
comprised of the transformer nameplate voltages for each tap setting. The calculated turns-
ratio based on the nameplate voltages is compared with the measured turns-ratio to derive the
percentage error and Pass/Fail results. By using a test plan, a transformer can be quickly tested
and turns-ratio Pass/Fail reports can be reviewed. Test plans can be created with the included
PC software and can be transferred to the ATRT-03 via the USB interface.
Optional Built-in Thermal Printer
The TRF-100 can be outfitted with an optional built-in 4.5” wide thermal printer that can be
used to print test results.
