Advantages

Full-Scenario Testing Capabilities, Covering Core Needs of CT/PT

1. Comprehensive CT testing functions, including 10 core parameters such as excitation curve, turns ratio, ratio and phase error, polarity, winding resistance, secondary burden, etc. It supports protection CT error curve and transient parameter testing, fully meeting in-depth detection needs.
2. Accurate and efficient PT testing, capable of completing turns ratio, phase angle error, polarity, secondary burden and winding resistance tests, adapting to routine detection and performance evaluation of PT of different specifications.
3. Supports nameplate information guessing function. When CT/PT nameplate is missing, key information such as rated current and accuracy class can be automatically deduced through test data, solving on-site detection pain points.
4. Equipped with saturation hysteresis loop curve measurement and excitation parameter calculation capabilities, which can accurately locate knee point voltage/current, providing core data for equipment aging evaluation and fault prediction.

Safe and Reliable Design, Adapting to Complex Scenarios

The equipment has a complete safety protection mechanism, must be reliably grounded, and high voltage is prohibited from direct access. It is necessary to confirm that there is no voltage at the terminals before testing to ensure the safety of operators and equipment.

Strong adaptability to working environment, temperature -10ºC~50ºC, humidity ≤90%, which can cope with complex scenarios such as substations and outdoor maintenance. Equipped with shielded test cables and special grounding cables, it has strong anti-interference ability, avoiding on-site electromagnetic interference affecting test accuracy. Strictly follows international electrical test standards, and operators must have high-voltage test qualifications to ensure compliance and safety of the detection process.
