Transformer Turns Ratio and Vector Group Tester
Edit
★ A. Light weight, strong load capacity!
★ B. Output current: Three-phase absolutely balanced, waveform is standard sine wave
★ C. Three-phase simultaneous adjustment, or each phase individually adjustable
Note: Three-phase high-current generator (current can be increased according to user requirements).
Functional features: (1) Imported iron core, small size and light weight
(2) 0.5 class digital true RMS meter
(3) No external standard CT and ammeter required
(4) Coarse and fine adjustment with zero position indicator, power supply 220/380/66V
The high-current generator uses an energy-saving high-permeability current booster, and the instrument is indicated by a true RMS 0.5 class digital meter. It is equipped with a digital electric stopwatch to meet time measurement requirements. It has the characteristics of large output power, strong overload capacity, clear readings, and flexible movement. It is suitable for power system technicians to test current transformers, protection devices, and secondary circuit current tests.
