Turn ratio, phase shift, excitation current, dc winding resistance readings,
transformer vector group, and polarity are displayed on a large LCD. Transformer
excitation current as well as phase shift angle helps to detect transformer shorted
turns or an unequal number of turns connected in parallel. Operating condition
(error) messages identify incorrect test connections, abnormal operating
condition, or winding problems. Test results can be saved internally within the
test set, printed out on an optional printer, or uploaded to a personal computer
(PC).
Features include:
 Fully automatic operation.
 Self-checking at power-up.
 Self-calibration at each measurement.
 User-friendly, menu-driven operation.
 Test turn ratio, phase shift (in either degree or centiradian), excitation current,
vector group (1PH0 or 1PH6), dc winding resistance and polarity.
 Easy measuring of single and three phase (phase by phase) transformers, as
well as potential & current transformers.
 Storage capacity for up to 200 tests results for retrieving, printing out, or
uploading to a PC.
 Saving up to 100 custom transformer settings for faster and easier testing.
 Checking reverse connections at start of each test.
 External optional printer records test data.
 External PC or laptop can be connected instead of a printer to transfer test
results and to provide full transformer test report.
 Quick test mode provides the fastest testing of a transformer.
 Two auto selected excitation test voltages: 8 V, and 1.5 V.
 Testing to ANSI, IEC, or Australian standards.
 Leads marked to ANSI, IEC, and Australian standards.
 Choice of six languages.
