GY-BZL transformer no-load load characteristic tester can measure the AC voltage of single-phase or three-phase power transformers simultaneously in accordance with the technical standards of JB/T501-91 "Power Transformer Test Guidelines" and GB1094-96 "Power Transformer" and effective Value, voltage average, effective value, active power, power factors and frequency and other power parameters, measurement accuracy is 0.1 level, intelligent and professional design, suitable for testing of power transformers no-load, load, induction and other tests, is traditional Ideal replacement equipment for pointer instruments.

Product Features

1. A single machine can complete the load test at the full current of the distribution transformer below 1000KVA; a single machine can complete the load test at the full current of the distribution transformer below 2500KVA (at one third of the rated current, the instrument can Convert to load loss parameters at rated current).

2. 240*120 Ultra-large blue screen LCD monitor, Chinese operation menu, high-speed thermal printer printing test results and history records.

3. The instrument can be preset 20 sets of parameters by the user, and these parameters can be deleted and added at any time as needed, making it more convenient to use. 

4. 20 sets of test results can be stored, and the test results are stored in advanced storage.

5. The data stored in parameters and test results adopts a strict inspection mechanism to ensure the correctness and reliability of parameters and test results.

6. High-performance processors are used as the core of control and computing, with fast sampling speed and good data stability.

7. External voltage transformers and current transformers can be connected to expand the measuring range of the instrument.

8. In order to improve measurement accuracy, this instrument has specially set two measurement gears, which are higher in low power factor testing. 

9. The instrument is small in size, light in weight and easy to carry.
