Transformer Testing Trainer
Single-phase and three-phase transformer bench for ratio, regulation, loss, and connection tests.
Transformer Testing Trainer photoPhotograph pending.
Transformer units with tapped windings and shrouded terminals, a switched load bank, and the meters an open-circuit and short-circuit test needs, so equivalent circuit parameters, regulation, and efficiency come out of measured data. Three-phase connection groups and parallel operation run on the same bench, which keeps a machines laboratory to one workstation per group.
