TTS: Transformer Test Equipment
Transformer Test Systems
The TTS Series are self-contained test sets incorporating all features necessary for testing single- and three-phase distribution transformers. To perform tests, the output leads of the test set are connection to the secondary terminals of the transformer under test. The rated secondary voltage is then applied to the transformer. At rated voltage, excitation current and excitation losses are measured. Impedance loss, impedance voltage and full load current tests are performed by reconnecting the output of the test set to primary of the transformer and shorting the secondary terminals. The test set is then used to circulate rated current.
