Introduction:
(1) Data processing adopts automatic storage and microcomputer printing. All test data are filled into corresponding tables in real time, avoiding manual transcription and recording process, ensuring the authenticity and reliability of data.
(2) Voltage and current ratios can be set, and measured values are displayed directly;
(3) The test bench uses Access database to save raw data, which can conveniently store all parameters of the tested equipment, test data, ambient temperature, test date and other information together, forming equipment files for future query and analysis.
(4) Can measure power in low power factor range;
(5) Strong anti-interference, with overload alarm indication, wrong wiring protection, overvoltage and overcurrent protection functions.
Product Quotation Features:
◆ The transformer characteristic test bench integrates one-time wiring display, data acquisition, analysis and processing, measurement control, storage, printing, and protection. The entire test process is automatically completed, with outstanding advantages of high efficiency and high precision.
◆ The transformer characteristic test bench is equipped with a liquid crystal backlit display, simultaneously showing 18 parameters such as three-phase voltage and current; digital meters replace pointer meters, and all test data are displayed in real time (locked) on the screen, avoiding errors caused by parallax, conversion, calculation and other factors during the test process. This makes the test accuracy higher. In particular, it completely solves the difficulty of operators reading multiple meters at the same time and recording multiple sets of data simultaneously, ensuring the accuracy and reliability of test data.
◆ Data processing adopts automatic storage and microcomputer printing, with beautiful and standardized data tables, neat and clear handwriting. All test data are filled into corresponding tables in real time, avoiding manual transcription and recording process, ensuring the authenticity and reliability of data. Users can also set printing formats as needed.
◆ The transformer characteristic test bench also has waveform distortion correction, test wire resistance correction, and transformer error correction functions.
◆ According to user needs, it can be made into desktop, portable, simple, standard types, convenient for use in different occasions.
◆ Multi-screen menu operation, convenient operation, automatic calculation of various parameters.
◆ Voltage and current ratios can be set, and measured values are displayed directly.
◆ The test bench uses Access database to save raw data, which can conveniently store all parameters of the tested equipment, test data, ambient temperature, test date and other information together, forming equipment files for future query and analysis.
◆ Can measure power in low power factor range.
◆ Strong anti-interference, with overload alarm indication, wrong wiring protection, overvoltage and overcurrent protection functions.
