ZXTQ-202 Two Way Transformer Power Quality Analyzer with 10A Impulse Current and 5km Range for Distribution Network Analysis
Professional two-way transformer analyzer featuring dual identification methods (carrier signal and impulse current) for accurate user area mapping. Provides comprehensive power quality monitoring including harmonic analysis up to 51st order, voltage waveform display, and real-time data analysis. Ideal for distribution network management with 2.7km carrier range and 5km impulse capability.
The ZXTQ-202 Two Way Transformer Power Quality Analyzer is a professional-grade device for distribution network analysis and user identification. Comprising a main unit installed at the transformer and a handheld terminal for field use, this system provides comprehensive power quality monitoring and area identification capabilities.
This analyzer employs two complementary identification methods that can be used independently or in combination:
- Power line carrier signal method for standard identification
- Impulse current method for challenging transmission conditions
- Accurate user wire connection analysis and phase identification
- Advanced data analysis displaying user quantities per area and phase
- Real-time power system harmonic measurement (3rd to 51st odd order)
- Voltage waveform display and voltage differential measurement
- Flexible testing with 1-3 clamp meters for various scenarios
- User-friendly menu system with guided testing procedures
- Customizable area numbering for transformer differentiation
- Non-directional impulse method testing for simplified operation
