CTP-200 CT/PT Analyzer | 40kV Knee-Point Testing, 0.05% Accuracy, IEC/IEEE Compliant

CTP-200P CT analyzer

——High-precision CT analyzer based on low-frequency frequency conversion technology

The Haomai CTP-200 CT/PT Analyzer revolutionizes transformer testing with 40kV knee-point voltage measurement, 0.05% accuracy, and full compliance with IEC 61869/IEEE C57.13 standards. Designed for field and lab use, this lightweight (9kg/19.84 lbs) instrument performs 13+ critical tests—including excitation curves, ratio/phase errors, and winding resistance—in seconds via its patented rotary mouse.

Key Applications:

Grid Maintenance: Validate CT/PT performance in substations, power plants, and industrial facilities.
Manufacturing QA: Ensure IEC accuracy for protection and metering transformers.
R&D Labs: Capture nonlinear inductance and transient parameters for advanced CT modeling.
