HDBR-IV Transformer Energy Efficiency Rating Tester

1、 Functional Features

HDBR-IV Transformer Energy Efficiency Rating TesterIt is an upgrade of our company's transformer capacity tester by our R&D personnel. Continuing the advantages of our original instrument, such as small size, simple operation, and easy use, we have comprehensively upgraded the internal processor, data acquisition system, and national standard data, making the instrument more widely available and with higher testing accuracy.

The transformer capacity characteristic tester includes functions such as transformer capacity, transformer no-load loss, transformer load loss and its code level determination, and electrical parameter measurement. The instrument comes with a high-performance rechargeable battery inside, which can work without an external power source. A single charge of the battery can continuously measure more than 200 transformers. In addition, the instrument can provide a three-phase precision 50Hz sine wave AC test power supply. When measuring transformer capacity and transformer load loss, there is no need to connect an external three-phase test power supply or auxiliary equipment such as voltage regulators and current boosters, greatly improving your work efficiency.

This product has many advantages such as small size, light weight, high measurement accuracy, good stability, and simple operation. It can replace the traditional method of measuring transformer loss and capacity using multiple meters, with simpler wiring, easier testing and recording, greatly improving your work efficiency.

l Adopting ARM+FPGA+ADC mode, coupled with RT Thread real-time operating system, the instrument system is more robust and the measurement accuracy is higher.

l 7-inch color high brightness LCD, icon style touch interface, Chinese input, full Chinese menu.

l Equipped with electronic assistance, all operations have wiring diagrams and textual descriptions, making the operation intuitive and simple.

l Built in large capacity storage, capable of storing 1000Group testing data. USB port communication, on-site test data can be saved, and data can be uploaded to a PC according to customer needs.

l Integrated with mainstream wired (R)S232）Wireless communication (Bluetooth, W)IFI function, convenient for data uploading and remote control.

l Equipped with remote program upgrade function, instrument programs can be remotely upgraded according to customer requirements.

l Real time waveform displays of voltage and current channels can be observed on each testing interface.

l Real time display of voltage, current, frequency, power factor, active power, reactive power, and apparent power of the test circuit through a single interface, in order to determine the on-site wiring situation.

l Standard customized low-voltage short-circuit wire, no need for screws and wrenches, can firmly short-circuit the tested transformer terminal, convenient for on-site testing.

l It can measure the capacity of various distribution transformers and electrical transformers on site, without the need for additional power supply, making detection more convenient and faster

l Combined with external power supply and equipment for voltage regulation, voltage boosting, and current boosting, various transformer characteristic data such as no-load current, no-load loss, impedance voltage, and load loss can be measured

l All test results have been automatically calibrated. You only need to input relevant parameters (such as temperature, no-load correction factor, etc.), and the instrument will automatically perform various corrections such as waveform distortion correction, temperature correction, non rated voltage correction, non rated current correction, etc., making the test results more accurate

l In the measurement of transformer characteristics, the maximum voltage range can reach 1000V, the maximum current range can reach 100A, and there is an internal protection circuit. When measuring, there is no need to switch gears to ensure measurement accuracy, and there is no need to worry about burning out the instrument due to incorrect gear selection

l When testing the characteristics of transformers, the voltage and current ranges can be flexibly and easily expanded by simply connecting external voltage transformers and current transformers, greatly expanding the testing range of the instrument

l Based on the test results of no-load and load losses, the performance level of three-phase oil immersed distribution transformers and electrical transformers can be automatically estimated for on-site reference by staff.
