Revolutionizing Field Testing: The ZXHQ-A+ Comprehensive Transformer Analyzer

Time:2025-06-11 Number:1

For technicians and engineers in power systems, transformer (CT/PT) testing has traditionally been a complex, time-consuming, and equipment-intensive chore. Manual voltage adjustment, meticulous data recording, intricate wiring changes, and post-processing curve plotting significantly slow down workflows and introduce potential for error. The ZXHQ-A+ Automatic Comprehensive Transformer Test Set fundamentally changes this paradigm, offering an integrated, automated solution that sets a new benchmark for efficiency, capability, and user-friendliness in the field.

Unmatched Automation & Ease of Use:
The core philosophy of the ZXHQ-A+ is simplification without compromise. Technicians simply input the transformer's rated parameters. The instrument then takes over:

Automated Testing: Executes the entire test sequence (excitation (V-I) curve, ratio, polarity, error curves, etc.) autonomously.

Automatic Calculation & Display: Instantly computes and displays critical results like ratio, polarity, and most importantly, renders the complete excitation curve graphically – eliminating manual plotting.

Reduced Labor & Error: Dramatically cuts down on manual tasks (wiring changes, voltage regulation, data logging, curve generation), boosting productivity and reliability on-site. Its intuitive interface and straightforward procedures make expertise accessible.

Comprehensive Testing Capabilities (Beyond the Basics):
The ZXHQ-A+ isn't just an excitation curve tester; it's a complete transformer validation suite:

1.Excitation (V-I) Characteristic: Industry-leading 2500V output (3000V opt.), capable of testing high-class (e.g., 500kV system) 1A CTs. Uniquely outputs real 50Hz sinusoidal waveforms, accurately simulating actual operating conditions (critical for valid diagnostics), with fine 0.13V resolution.

2.Ratio & Polarity: Massive 600A primary current injection (1000A opt.) for definitive ratio verification under load.

3.Accuracy Verification: Automatically plots 5%, 10%, and 15% error curves directly on the device.

4.Precision Metrology: Measures ratio error (±0.5%), phase error (±3 min), secondary winding resistance (0-20Ω, ±0.5%), and secondary burden.

5.Advanced Functions: Includes secondary loop resistance, secondary winding AC withstand voltage (2500V/5min), and demagnetization capabilities.

6.Compliance Assurance: Automatically selects and applies relevant test standards (GB1208, GB1207, etc.) based on transformer type and class.

Engineered for the Demanding Field Environment:

1.Robust Data Management: Stores 4000 test records internally (battery-backed). Seamlessly exports data via USB for detailed analysis and automated generation of professional Word reports using included PC software.

2.Modern User Interface: Features a vibrant 7-inch color touchscreen with intuitive graphical menus and crucially, built-in Chinese input for clear equipment identification. An integrated panel printer provides immediate hard copies of curves and results.

3.Connectivity: Offers PC remote control for lab-like flexibility in the field.

4.Portability Redefined: Achieving this level of capability in a single, integrated unit weighing only 26kg is a significant engineering feat, enabling true mobility for testing across diverse substation locations.

Technical Superiority in Key Metrics:

CT Excitation: 0-2500V/3000V(opt.), 0-20A, ±0.5%

CT Ratio: 0-600A/1000A(opt.) Prim., 0-7V Sec., ±0.5%

PT Excitation: 0-500V (Safe-limited), 0-20A, ±0.5%

PT Ratio: 0-2500V/3000V(opt.) Prim., ±0.5%

Resistance: 0-20Ω, ±0.5%

Primary Current Withstand: 200A / 5 minutes

The Clear Advantage:
Compared to traditional methods involving separate test sets (variable AC sources, precision meters, recorders) and laborious manual processes, the ZXHQ-A+ delivers:

1.Radical Time Savings: Automating setup, execution, and curve generation compresses testing from hours to minutes.

2.Enhanced Accuracy & Consistency: Removes manual recording/plotting errors and ensures standardized application of test procedures.

3.Unparalleled Convenience: One compact device replaces multiple units and eliminates complex wiring juggling.

4.Comprehensive Compliance: Built-in standards and real sinusoidal output guarantee diagnostically valid results.

5.True Field Portability: Powerful lab-grade analysis in a genuinely transportable 26kg package.
The ZXHQ-A+ Automatic Comprehensive Transformer Test Set is not merely an improvement; it represents a transformative leap in field testing technology. By integrating the full spectrum of CT/PT verification tests into a single, automated, and portable platform that outputs real-world waveforms, it empowers technicians to perform exhaustive, standards-compliant assessments with unprecedented speed, simplicity, and confidence. For utilities and service teams prioritizing grid reliability, workforce efficiency, and data-driven maintenance, the ZXHQ-A+ establishes itself as the indispensable modern solution for transformer commissioning and diagnostics.
