JCRL type active transformer capacity characteristic testerDetailed product description：

The JCRL type active transformer capacity characteristic tester can accurately measure a series of power frequency parameters such as capacity, no-load current, no-load loss, short-circuit loss, impedance voltage, etc. of various transformers. This instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation and learning. It can completely replace the previous method of measuring transformer loss and capacity using multiple meters. The wiring is simple, the testing and recording are convenient, and the work efficiency is greatly improved. It uses a large screen image LCD as the display window, with graphical menu operation and Chinese character prompts. It integrates multiple parameters into a single screen display interface, with a user-friendly human-machine dialogue interface. It is easy and fast to use, and is the preferred product for power users at all levels.

Functional characteristics of active transformer capacity characteristic tester
1. It can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. It can measure the no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero sequence impedance of various types of transformers.
3. It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non rated voltage), and current correction (short-circuit test under non rated current conditions). Operators only need to input the correction index instrument according to the transformer type to automatically calculate the corrected results, which is very suitable for units that do not have slightly larger capacity transformer short-circuit test conditions.
4. It is allowed to use external voltage transformers and current transformers for extended range measurement, which can measure any parameter of the test sample.
5. Voltage circuit width limit: The maximum voltage that can be measured is 750V, and accuracy can be ensured without switching gears. The instrument itself will not be damaged due to incorrect voltage gear selection.
6. Large screen, high brightness LCD display, full Chinese character menu and operation prompts for friendly human-machine dialogue, touch buttons for easier operation, wide temperature LCD with brightness adjustment, suitable for winter and summer seasons.
7. Users can print out the results of the test data at any time through a micro printer.

Precautions for use
1. During the measurement process, be sure not to touch the metal parts of the test line to avoid being damaged by electrical shock.
2. When measuring wiring, it is necessary to strictly follow the instructions, otherwise the consequences will be borne by oneself.
Before testing, it is necessary to carefully check whether the set parameters are correct.
4. It is best to use a grounded power socket.
5. Cannot operate under excessive voltage and current limits.
During the short-circuit test, the short-circuit on the non pressurized side must be in good condition, otherwise it will affect the test results.
When conducting a short-circuit test, if the high-voltage or medium voltage side outlet bushing is equipped with a ring current transformer, the secondary of the current transformer must be short circuited before the test.
8. The test wiring work must be carried out with the tested circuit grounded to prevent induced voltage electric shock. All short circuits, grounding, and leads should have sufficient cross-sectional area and must be securely connected. The testing organization work should be rigorous and communication should be smooth to ensure the safe and smooth progress of the testing work.
