Product Description

Transformer Loss Parameter Tester

Darui Electric recommends for you

I. Product Features:

1. The transformer loss parameter tester can measure the no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance of various types of transformers.

2. It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), current correction (short-circuit test under non-rated current), and additional loss correction for short-circuit tests. The operator only needs to input the correction index based on the transformer type, and the instrument will automatically calculate the corrected results.

3. It allows external connection of voltage transformers and current transformers for extended range measurement.

4. Wide measurement range for voltage and current loops: voltage can be measured up to 750V without switching gears to ensure accuracy. It will not damage the instrument due to incorrect voltage gear selection; current can be directly tested up to 100A.

5. Large screen, high-brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction, touch buttons for easier operation, and LCD brightness adjustment suitable for winter and summer seasons.

6. Users can print out test data at any time through the 232 interface connected to an external micro printer (printer is optional).

7. For users with high-voltage test vehicles, an RS232 serial port for computer communication is reserved, which can expand the calibration data upload function and achieve centralized data management.

III. Product Introduction:

　　The transformer loss parameter tester is mainly used for measuring transformer loss parameters, and can accurately measure parameters such as no-load loss, no-load current, load loss, and impedance voltage of various transformers. This instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation, and can completely replace the previous multi-meter method for measuring transformer losses. It has simple wiring, convenient testing and recording, and greatly improves work efficiency. It uses a large-screen graphical LCD as the display window (with both color and monochrome configurations, users can choose freely), graphical menu operation with Chinese prompts, and a display interface that integrates multiple parameters on one screen. The human-machine interface is friendly, and it is easy and quick to use.

　　The transformer loss parameter tester consists of two parts: the main unit and the accessory box. The main unit is the core of the instrument, with all electrical parts inside. The outer case of the main unit uses high-strength imported waterproof injection-molded case, which is sturdy and durable. The accessory box is used to store test leads and tools.
