XHZK1620 Low Voltage Short-Circuit Impedance Tester — a portable instrument for on-site and laboratory low-voltage short-circuit impedance measurement of 35kV and above main transformers, used to check whether windings have deformed after short-circuit or mechanical impact.
The low-voltage short-circuit impedance test is the most direct method to check whether the windings of a transformer have deformed after it has been subjected to a short-circuit current impact, or to mechanical impact during transport and installation. It is important for judging whether a transformer can be put into operation, and it is also one of the bases for deciding whether disassembly inspection is required.
The XHZK1620 is a new-generation transformer parameter tester independently developed by the manufacturer, for on-site and laboratory low-voltage short-circuit impedance measurement of 35kV and above main transformers. With a built-in 2000 W adjustable power supply and advanced A/D synchronous AC sampling and digital signal processing, it delivers accurate measurement data. It features a large color LCD with Chinese menu prompts, a high-speed thermal printer, a large internal memory, and USB data transfer to a flash drive — in a small, light and portable package.
Main Test FunctionsThe XHZK1620 covers three test modes in a single unit, matched to different transformer conditions:
| Mode | Applicable Transformer | What It Measures | Connection Highlights |
|---|---|---|---|
| Three-phase short-circuit impedance | Three-phase transformers (star or delta HV winding) | Three-phase voltage, current and power; impedance voltage percentage and nameplate error | Single-phase supply applied at AB, BC, CA; LV side shorted; auto or manual mode |
| Single-phase short-circuit impedance | Single-phase transformers | Short-circuit impedance | Test leads on the transformer; CT/PT used only with external supply |
| Zero-sequence impedance | Transformers with HV star connection and neutral point | Zero-sequence impedance | HV three phases combined, LV open; test voltage below rated phase voltage |
For three-phase transformers, the instrument adopts a single-phase supply applied in turn to AB, BC and CA, then automatically converts the results to the three-phase test method — that is, the three-phase transformer single-phase measurement method.
Technical Specifications| Voltage (auto range) | 15 – 500V, ±(0.2% of reading + 3 digits) |
| Current (auto range) | 0.5A – 20A, ±(0.2% of reading + 3 digits) |
| Power | COSΦ > 0.15, ±(0.5% + 3 digits) |
| Frequency (power frequency) | 45 – 55Hz, accuracy ±0.1% |
| Short-circuit impedance | 0 – 100%, accuracy ±0.5% |
| Display | 4-digit readout, 7-inch touch color LCD |
| Built-in power supply | 2000W AC adjustable, 0–220V, 10A |
| Memory | Stores up to 200 measurement records |
| Printer | Built-in high-speed thermal printer |
| Interfaces | RS232 and USB flash-drive port |
| Working power | AC 220V ±10%, 50Hz ±1Hz |
| Ambient temperature | -10°C – 40°C |
| Relative humidity | ≤85%RH |
The XHZK1620 is aimed at the teams that verify the condition and impedance of large power transformers:
The instrument carries a one-year warranty against quality problems from the date of manufacture (other damage is charged at material cost only), and the manufacturer provides lifetime repair and technical service. Please do not disassemble the instrument yourself; contact the company for the most convenient handling solution.
Standard kit: main unit, test leads, power cord, fuses, printer paper and ground wire.
