Product Introduction;
It can measure the capacity, no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero-sequence impedance of power transformers. It can automatically perform waveform distortion correction, temperature correction, voltage and current (non-rated) correction. It allows external connection of voltage transformers and current transformers to expand the range, and can measure test samples with arbitrary parameters. The maximum voltage that can be measured is 750V, and accuracy is guaranteed without changing gears.
◆The instrument has exquisite circuit design, unique thinking, superior performance, and powerful functions, fully meeting the requirements for on-site capacity testing of distribution power transformers.
◆The instrument uses advanced A/D synchronous AC sampling and digital signal processing technology internally. It is simple to operate, convenient to connect, and provides accurate and reliable data, solving the difficult problem of capacity testing for distribution transformers. It can also display and print the measurement data that users care about.
◆The instrument is mainly used for capacity testing of distribution transformers. The built-in test power supply can complete capacity tests for 100 units of 2500kVA and below distribution transformers on a single charge.
◆The human-machine interface of the instrument uses a blue screen (240 * 128) full Chinese character graphic display. The menu is strictly hierarchical, guiding you step by step through the test. You only need to power on and press any key, and the menu provided by the instrument will guide you through the required test. Using this instrument can greatly improve work efficiency and reduce labor intensity.
Transformer Capacity Characteristic Tester
Product Features;
1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Built-in power supply, automatically generates three-phase high-power test power.
3. Can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. Can automatically perform waveform distortion correction, temperature correction (providing two methods: simple temperature correction and separate additional loss correction), voltage correction (no-load test under non-rated voltage), and current correction (short-circuit test under non-rated current conditions). It is very suitable for units that do not have conditions for short-circuit tests on slightly larger capacity transformers.
5. Can measure the harmonic content and total harmonic distortion of voltage and current.
6. Can perform simple vector analysis and draw vector diagrams.
7. Displays waveform diagrams of various electrical parameters, serving as an oscilloscope.
8. Wide voltage range: voltage can be measured up to 800V, and accuracy is guaranteed without switching gears. The instrument will not be damaged due to incorrect voltage gear selection.
9. Capacity measurement range: 20KVA~100000KVA.
10. Battery remaining percentage indication function, not just a simple low battery alarm.
11. Large screen, high brightness color LCD display, full Chinese menu and operation prompts for friendly human-machine dialogue, conductive silicone touch keys for easier operation and longer key life.
