LWD 6510 Transformer Short Circuit Impedance Tester Features: 1. Measurement of short-circuit impedance: Used for low-voltage short-circuit impedance experiments of transformers, it can display and measure parameters such as voltage, current, active power, impedance value, impedance voltage percentage, reactance value, leakage inductance value, etc. on the same screen in three or single phases. 2. Measurement of no-load loss: The instrument displays three-phase voltage, three-phase current, and three-phase power, displays the distortion rate of the applied power waveform, and calculates the percentage of no-load current and no-load loss of the transformer. 3. Measurement of load loss: Display three-phase voltage, three-phase current, and three-phase power, automatically calculate the impedance voltage percentage of the transformer, and convert it to the load loss at rated temperature and current. The instrument has a frequency conversion function, which can accurately measure over a wide frequency range. 4. Phase separation measurement: Used to check for defects in single-phase windings of three-phase transformers or situations where there is no three-phase power supply on site. The split phase test uses a single-phase power supply, and after measuring each single-phase data separately, it can automatically be converted into three-phase parameters. 5. Measurement of zero sequence impedance: The measurement of zero sequence impedance is applicable to transformers with neutral points in the high-voltage side star connection. The instrument can record zero sequence impedance, zero sequence reactance, zero sequence inductance, impedance angle, and zero sequence resistance. 6. The instrument has a harmonic analysis function, which can measure the content and total distortion rate of multiple harmonics, and display the original waveform and histogram. 7. The instrument has a large LCD display, which can display three-phase voltage, three-phase current, three-phase power, three-phase impedance value, three-phase impedance voltage percentage, three-phase reactance value, three-phase leakage inductance value, three-phase average voltage, average current, three-phase total power, and related data on the same screen. The instrument adopts a Chinese menu with Chinese prompts and easy operation. 8. The instrument is equipped with a USB flash drive interface, which allows the data stored in the instrument to be imported into the USB flash drive at any time. During instrument testing, it can be directly stored in the USB flash drive. 9. Built in memory, no loss upon power failure, the instrument can store 400 sets of data. 10. The system comes with a printer, which can print test data and memory browsing data. 11. Permanent calendar and clock functions, allowing for time calibration. Technical parameters: 1.
