Transformer Empty Load Characteristics Analyzer

HZKZ-50A transformer empty load characteristics analyzer, is the latest product, the instrument uses today's popular ARM processor, 168M memory 128M memory expansion 4G memory card. LCD with 7-inch high-definition color touch screen, combined with emwin display interface, the instrument friendly interface is simple, full touch screen operation without the keyboard. The instrument supports the database and can be exported via USB flash drive or through the data cable to the back-end computer.

The instrument circuit design sophisticated, unique thinking, making its superior performance, powerful, small size, light weight. Not only to test the transformer's empty load parameters, but also to measure the harmonic content of the scene, and the waveform. Instrument recordable transformer empty load test curve provides a reliable basis for transformer fault analysis.

The wiring and precautions

1. Please use the instrument according to the instructions for wiring and operation.
2. The ground terminal of the ground terminal or power cord should be grounded reliably.
3. Please enter the correct parameters before the test, enter the storage serial number can save the test results in this record number, and then set the parameters according to the parameters of the transformer under test, the settings are complete Click the save modify button to save and enter the test interface, select the desired Test the parameters (impedance or parameters), click the Start button, and then slowly raise the test voltage to complete the test. End of the test Click the end button and save the test record to complete the test.
4. The instrument is full touch screen operation, do not bump.

The main functions and features:
1. The instrument uses 7-inch true color LCD, can measure the voltage, current, angle, power and other electrical parameters, and can show the voltage and current of the vector diagram, with the screen display is clear and intuitive.
2. Measurable transformer no-load loss, load loss, impedance voltage and other parameters.
3. The instrument has the harmonic analysis function, which can measure the 1-32th harmonic content of the voltage and current applied on the transformer, and can display the bar graph and voltage and current waveforms.
4 can automatically record the transformer empty load test process, the different voltage and current load characteristics of the empty curve, easy to analyze the characteristics of the transformer and the core.
5. With data storage and data browsing capabilities, the instrument supports DBF database, according to user needs to store test data or browse test records. Instrument also supports USB export function, you can export test data through the USB flash drive, the database supports Excel spreadsheet open, easy to edit print or archive
6. Using 7-inch true color touch screen operation, emwinGUI interface, built-in 128M memory (expandable 4G memory card), support for Chinese input, easy to operate.
