PUSH Electrical PS-BB103 Transformer turns ratio tester TTR
During transformer production, before installing a newly made transformer, the turns ratio or voltage ratio should be tested according to IEC and national standards, including verification of correct turn ratio, tap-changer condition, short circuit between turns, and readiness for parallel operation. The PS-BB103 turns ratio tester replaces the complicated traditional bridge method by enabling direct reading and provides three-phase voltage ratio/turns ratio testing in one cycle with fast operat

(1) The instrument uses a precision three-phase inverter measurement power supply instead of a single-phase mains supply for measuring voltage. This eliminates the harmonic effect of the main voltage and improves accuracy. If the working power supply is a generator, it is also not affected.
(2) Using three-phase output voltage improves test speed. The instrument can measure the phase angle between phases and automatically identify transformer wiring groups 0–11.
(3) Suitable for various transformers, with test capabilities for Z-type transformer rectifier transformers, grounding transformers, electric furnace transformers, phase-shifting transformers, balanced transformers, Scott transformers, and Inverse Scott transformers.
(4) The precision three-phase inverter power supply provides high-/low-voltage reverse connection protection, transformer inter-turn short-circuit protection, tap-changer protection, and output short-circuit protection, improving instrument stability.
(5) After inputting rated parameters, the instrument can automatically measure transformer turns ratio, error, and tap-changer points—especially for asymmetric tap-changer points. It can also accurately test the transformer tap-changer position, measuring up to 99 tap positions.
(6) Features a 65K True Color Module LCD display. Each operation step includes English prompts, allowing completion through on-screen guidance without manual operation.
(7) Includes a micro-printer and USB and RS232 interfaces.
(8) Equipped with a sealed, waterproof, shock-proof, sturdy carrying case, suitable for field testing.
(9) Android mobile phones can install the dedicated software by following the WeChat public account, connect the instrument for full process control via Bluetooth, and store test data in a fixed format on the mobile phone—making data retrieval convenient at any time.
