Factory Price Low Voltage Transformer Short-Circuit Impedance Tester
The High-Precision Transformer Short-Circuit Impedance Tester is a professional testing instrument developed for transformer manufacturing inspection, type testing, and precision maintenance. Adopting advanced digital signal processing (DSP) technology and high-precision sampling components, it achieves ultra-high measurement accuracy, fully complying with IEC and GB national standards. This tester is widely used in transformer factories, electrical testing institutions, and power grid research departments, providing reliable data for transformer performance evaluation and quality control.
Key Features
- Ultra-High Measurement Accuracy: Voltage and current measurement accuracy up to ±0.05% FS, impedance measurement accuracy ±0.1% FS, ensuring precise test results for high-end transformer testing.
- Multi-Parameter Synchronous Measurement: Synchronously measures short-circuit impedance, load loss, power factor, harmonic content, and three-phase voltage/current imbalance, realizing comprehensive performance detection.
- Advanced Calibration Function: Built-in automatic calibration module, supporting standard resistor and voltage source calibration, ensuring long-term stability of measurement accuracy.
- Professional Data Analysis: Equipped with professional analysis software, supporting data comparison with standard values, trend analysis, and fault early warning, helping technicians identify potential problems.
- Strong Expandability: Reserved communication interfaces (RS485, Ethernet), supporting connection to upper computer systems, realizing centralized management and remote control of multiple instruments.
