Description
TRT63A is a true three-phase, fully automatic test set specially designed for turns ratio, phase shift and
excitation current measurements of power, distribution and instrument transformers. TRT63A
determines the transformer turns ratio by accurately measuring the voltages across the unloaded
transformer windings and then displaying the ratio of these voltages (ratios range from 0,8 to 50 000).
TRT63A is based on a state of the art technology, using the most advanced technique available today.
The test set can be used to test single-phase and three-phase transformers, both with and without taps
in accordance with the requirements of the IEC 60076-1 standard.
For a three-phase measurement, the test set is connected to all the three phases of a transformer to be
tested. If specific vector diagrams are selected for different types of transformers, the TRT63A will run a
specific test for each transformer type (i.e., single phase, Delta to y, Y to delta, Delta to delta, or Y to y)
without a need to switch the test hookup cables. It displays a turns ratio, phase shift and excitation
current, obtained with true three-phase and single-phase tests. With the AVGD test, TRT63A can
automatically detect vector group of a transformer.
TRT63A lets users enter a transformer’s nameplate voltages for the turns ratio deviation calculation.
This feature eliminates any error otherwise caused by an operator’s manual calculation. The TRT63A
also compares the test result with the calculated ratio and prints out the % of error for each test. It is
easy to read the instruments display and easy to follow the menu. There is enough memory in the
TRT63A to store 100 test records. Each record consists of 100 test readings. All measurements are
time and date stamped. The measurements can be printed on an optional built-in thermal printer using
the Print button.
The transformer excitation current, as well as the phase angles, help to detect transformer's shorted
turns or unequal number of turns connected in parallel. Operating conditions messages or error
messages identify incorrect test conditions, abnormal operating condition or winding problems.
TRT63A has a very high ability to cancel electrostatic and electromagnetic interference in HV electric
fields. It is achieved by a very efficient filtration. The filtration is made utilizing the proprietary hardware
and software design solutions.
