The loss parameter tester is a high-precision instrument specially developed and developed by our company for the measurement of no-load and load parameters of the transformer. It can accurately measure a series of parameters such as no-load current, no-load loss, short-circuit loss, and impedance voltage of various transformers.
The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, easy operation and easy learning. It can completely replace the previous method of measuring transformer loss and capacity by using the multi-meter method. It has simple wiring, convenient testing and recording, and greatly improved Improve work efficiency. It uses a large-screen graphic real-color LCD as the display window, graphic menu operation and Chinese character prompts, a multi-parameter display interface, friendly man-machine dialogue interface, easy and fast to use, and is suitable for power users at all levels. Preferred product.

Features
1. It can measure the no-load current, no-load loss, impedance voltage, load loss, and zero sequence impedance of various types of transformers.
2. It can automatically perform temperature correction, voltage correction (no-load test under non-rated voltage), current correction (short-circuit test under non-rated current conditions), and direct resistance correction. The operator only needs to input the correction index instrument according to the transformer type. The corrected result can be calculated automatically.
3. Wide range of voltage loop: The maximum voltage can be measured up to 750V, and the accuracy can be guaranteed without switching gears. The instrument itself will not be damaged due to the wrong selection of the voltage range.
4. The large screen, full Chinese character menu and operation prompts realize friendly man-machine dialogue. The conductive rubber buttons make the operation easier. The high-brightness true-color LCD display can be adapted to winter and summer.
5. The user can print out the test data through a micro printer at any time.
6. All test results can be saved in the form of records for future reference.
