High-voltage high-current dielectric loss tester (40 A)

1.By employing technologies such as digital waveform analysis and bridge self-calibration, in conjunction with a high-precision three-terminal standard capacitor, this instrument enables high-precision dielectric loss measurement. The input resistance across all measurement ranges is less than 2 Ω, thereby eliminating the influence of additional capacitance from the measurement cable. 2. The approach of combining high-voltage capacitors with a dielectric loss bridge simplifies the wiring and commissioning process while ensuring the safety of the bridge testing procedure. 3. Enables the use of a high-voltage power supply provided by series resonance, without requiring a fixed frequency. The instrument features built-in both series and parallel dielectric loss measurement models, facilitating instrument calibration. 4.Equipped with a standard current input channel, allowing the use of an external standard capacitor for dielectric loss measurement; the dielectric loss bridge can also be calibrated within the laboratory. 5.The controller and the high-voltage bridge utilize wireless communication, offering a long transmission range, high safety and reliability, and user-friendly operation. 6.The controller features a 7-inch color touchscreen with touch input and a USB port. 7. The controller supports unlimited data storage; data can be exported via a USB flash drive for computer-based data analysis. 8. The high-voltage bridge and controller are equipped with built-in rechargeable batteries; no external power supply is required during operation.
