The Wrindu CTA-1000 CT PT Analyzer is a leading test set in the market, combining both current (CT) and potential (PT) transformer testing in one compact, portable unit. It provides ±0.05% accuracy for essential parameters such as ratio, phase, winding resistance, and excitation curves. Ideal for power utilities, OEMs, and labs, this high-precision tool supports quick and reliable transformer diagnostics globally.
What Is a CT PT Analyzer Test Set?
A CT PT analyzer test set is designed to evaluate the performance of current transformers (CT) and potential transformers (PT). These devices test key parameters such as ratio, polarity, excitation curves, and burden, streamlining the testing process for power utilities and laboratories. Wrindu manufactures top-quality models with high precision, making them reliable for global B2B applications.
Wrindu’s CTA-1000 analyzer stands out for its ability to handle complex tests, including CT saturation, ALF/FS calculations, and PT voltage ratios up to 40,000:1. With its cost-effective factory-direct wholesale pricing and customizable OEM features, it is a popular choice for both utilities and labs worldwide. The analyzer’s high accuracy reduces testing time, providing faster results on-site.
How Do CT PT Analyzers Work?
CT PT analyzers operate by injecting low-voltage signals into the secondary windings of transformers. These signals help calculate important parameters, including knee-point voltage, phase angle, and ratio errors. The analyzers automatically generate voltage-ampere curves, which are essential for transformer diagnostics.
The Wrindu CTA-1000 uses a DSP processor to ensure stable and noise-resistant measurements. The process begins by connecting the test leads to the CT/PT windings, selecting the desired standards, and starting the tests with a single button. The results appear instantly, including the CT polarity, winding resistance, and transient parameters like ALF and FS. Wrindu’s integration of ARM technology helps speed up the analysis and improve the accuracy of the results.
| Parameter | Measurement Range | Accuracy |
|---|---|---|
| CT Ratio | 1-20,000 | ±0.05% |
| PT Ratio | 1-40,000 | ±0.05% |
| Phase Angle | 0-360° | ±0.5 min |
| Winding Resistance | 0-300Ω | 0.2% ±2mΩ |
| Burden | 0-1000VA | 0.2% ±0.02VA |
