Transformer Capacity Tester

Transformer capacity characteristic tester includes functions such as transformer capacity, no-load loss of the transformer, load loss of the transformer and its code level determination, and electrical parameter measurement. The instrument has a high-efficiency rechargeable battery inside and can work without an external power supply. A fully charged battery can continuously measure more than 200 transformers. In addition, the instrument can provide a three-phase precise 50Hz sine wave AC test power supply. When measuring the transformer capacity and the load loss of the transformer, there is no need for an external three-phase test power supply, voltage regulators, current boosters and other auxiliary equipment, thus 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 completely replace the previous method of measuring transformer losses and capacity using multiple meters. The wiring is simpler and the testing and recording are more convenient, which greatly improves your work efficiency.

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

2.     7-inch colorful high-brightness LCD, icon-based touch interface, Chinese input, and all Chinese menus.

3.     With perfect electronic help, each operation has wiring diagrams and text descriptions, and the operation is intuitive and simple.

 4.     Built-in large-capacity memory can store 1000 sets of test data. USB port communication, on-site test data can be saved, and data can be uploaded to the PC according to customer needs.

5.     Integrated with mainstream wired (RS232) and wireless communication (Bluetooth, WIFI) functions for convenient data upload and remote control.

6.     In each test interface, the waveform diagrams of the real-time voltage channel and current channel can be observed.

7.     Through a single interface, the voltage, current, frequency, power factor, active power, reactive power, and apparent power of the test circuit are displayed in real time to facilitate the judgment of on-site wiring conditions.

8.   Standard with custom low-voltage short connection wires, without screws and wrenches, it can firmly short-circuit the connection terminals of the tested transformer, which is convenient for on-site testing.

9.   Various capacities of distribution transformers and power transformers can be measured on-site without an additional power supply, making the detection more convenient and faster.

10.  Combined with external power supplies and equipment such as voltage regulation, boost, and current increase, characteristic data such as no-load current, no-load loss, impedance voltage, and load loss of various transformers can be measured.

11.  All test results are automatically corrected. You only need to input relevant parameters (such as temperature, no-load correction coefficient, etc.), and the instrument can automatically perform various corrections such as waveform distortion correction, temperature correction, non-rated voltage correction, and non-rated current correction to make the test results more accurate.

12.  In the measurement of transformer characteristics, the maximum voltage range can reach 1000V, and the maximum current range can reach 100A, and there is a protection circuit inside. When measuring, the measurement accuracy can be guaranteed without switching gears, and there is no need to worry about burning the instrument due to the wrong gear selection.

13.  During the transformer characteristic test, both the voltage and current ranges can be expanded very flexibly and simply by simply connecting external voltage transformers and current transformers, which greatly widens the test range of the instrument.

14.  According to the no-load and load losses in the test results, the performance level of three-phase oil-immersed distribution transformers and power transformers can be automatically inferred for on-site reference by staff.
