Product feature and application

1. Accurately measures the capacity of various distribution transformers through passive measurement, offering convenience and precision.

2. Features an internal power supply that automatically generates a three-phase high-power test source.

3. Measures no-load current, no-load losses, short-circuit voltage, and short-circuit losses for all transformer types.

4. Accurately identifies transformer models through no-load testing, including: S7, S9, S11, S13, S15, dry-type transformers SCB9, SCB10, SCB11, and other types.

5. Automatically performs waveform distortion correction, temperature correction (offering both simple temperature correction and separate additional loss correction), voltage correction (for no-load tests at non-rated voltages), and current correction (for short-circuit tests at non-rated currents). This makes it highly suitable for facilities lacking the capacity to perform short-circuit tests on larger transformers.

6. Measures voltage and current harmonic content and total harmonic distortion (THD).

7. Performs basic vector analysis and plots vector diagrams.

8. Displays waveforms of electrical parameters, functioning as an oscilloscope.

9. Wide voltage measurement range: Measures up to 750V without tap switching, ensuring accuracy. Prevents instrument damage from incorrect voltage range selection.

10. Capacity measurement range: 20kVA to 240,000kVA.

11. Battery remaining capacity percentage indication-far more than a simple low-battery alarm.

12. High-resolution, high-brightness true-color LCD display. Fully English menus and operation prompts enable user-friendly interaction. Conductive silicone touch keys simplify operation and extend key lifespan.

13. Users can print test results anytime via the built-in micro printer.

14. Test result storage function, capable of storing 200 sets of capacity test data.

FAQ

1)Does the MEBRT-WII Transformer Capacity and Loss Parameter Tester require an external power source to operate?

Answer: No. This instrument features a high-efficiency rechargeable battery that supports continuous measurement of up to 500 units per charge. It can independently perform capacity, loss, and other parameter tests without an external power supply, making it particularly suitable for field scenarios without power access.

2)What transformer models can the MEBRT-WII Transformer Capacity and Loss Parameter Tester identify?

Answer: It accurately identifies multiple transformer types through no-load testing, including series classified by core energy efficiency levels (S7, S9, S11, S13, S15) and dry-type transformers (SCB9, SCB10, SCB11). It also supports testing non-standard transformer types (requires input of impedance and voltage parameters).

3)How are test results stored and output from the MEBRT-WII Transformer Capacity and Loss Parameter Tester?

Answer: Test results can be directly stored internally, with capacity test data capacity for up to 200 sets. Results can be instantly printed via the built-in micro printer or uploaded to a backend management computer through the USB communication interface for subsequent querying and management.
