CT Analyzer
A Current Transformer Analyzer is an intelligent diagnostic device integrating measurement, analysis, and assessment capabilities. It specializes in comprehensive evaluation of current transformer (CT) performance and fault detection, focusing on data modeling, trend analysis, and failure prediction beyond basic testing.
I. Core Functions
1.Full-Parameter Measurement
Automated tests: Ratio, polarity, excitation characteristics (V-I curve), DC resistance, ratio/phase error, secondary burden.
2.Advanced Data Analytics
Core Hysteresis Modeling: Analyzes remanence, saturation point drift, and core aging via excitation curves.
Dynamic Error Compensation: Calculates real-world measurement/protection errors using load/temperature data.
Trend Warning: Alerts for insulation degradation or interturn shorts (e.g., >5% annual DC resistance increase).
3.Fault Diagnosis
Auto-identifies critical failures:
Saturation Failure (30% knee-point voltage drop → protection failure risk)
Reverse Polarity (cause of differential protection maloperation)
Secondary Overload (burden excess causing measurement distortion)
II. Unique Advantages
Smart Reporting
Generates risk-graded diagnostic reports
Digital Twin Simulation
Creates virtual CT models to simulate behavior under fault currents (e.g., saturation check at 500kA).
Cloud Data Management
Enables multi-site CT health benchmarking and lifecycle tracking.
