Transformer Ratio TesterZC-203M

1.Simple & Intuitive Operation
Adopts an intelligent touch-controlled large color LCD screen with Chinese/English bilingual menu prompts, easy to operate without professional learning.
Test results are displayed directly without manual conversion, solving the problems of cumbersome operation and non-intuitive reading of traditional turns ratio bridges.

2.Efficient & Fast Testing
① Complete three-phase turns ratio test with one wiring connection in only 10 seconds, with far higher work efficiency than traditional single-phase test methods.
② Supports fully automatic three-phase test, which can be completed without manual parameter input.

3.Accurate & Stable Data
① Built-in high-stability sine wave test power supply, test voltage is automatically adjusted according to the load, unaffected by the quality of on-site mains or generator power supply.
② High test accuracy: measuring range 0.9–10000, ±0.1% error for values ≤2000, ±0.3% error for 2000–10000, minimum resolution 0.0001.

4.Flexible Power Supply for Multiple Scenarios
Dual power supply modes: AC 100–240V mains + built-in lithium battery, suitable for indoor laboratories, outdoor sites and other usage scenarios.

5.Wide Adaptability to Test Equipment
Capable of testing distribution transformers up to 1000kV large transformers, compatible with CT, PT, CVT and Z-connection transformers, covering mainstream power transformer equipment.

6.Comprehensive Protection Functions
Equipped with triple safety protection: high and low voltage reverse connection protection, transformer short-circuit protection and inter-turn short-circuit protection, ensuring equipment and personal safety.

7.Convenient Data Management
① Built-in memory can store 200 sets of test data with power-off data retention, and supports power-off clock and date display.
② Equipped with RS485 communication and USB interface for U-disk data export; optional Bluetooth communication and Bluetooth printing.

8.Convenient Fault Diagnosis
Built-in multiple winding short-circuit measurement methods, enabling quick location of transformer faults and improving maintenance efficiency.
