0.02% Accuracy Current Transformer Ratio and Phase Angle Error Test CT PT Analyzer with Laptop Control
Characteristics of GDVA-405 0.02% Accuracy Current Transformer Ratio and Phase Angle Error Test CT PT Analyzer
1) Comprehensive and accurate testing capability
One click automated testing:Automatically measure key parameters such as CT/PT ratio error, angle error, polarity, turns ratio, secondary winding resistance, excitation characteristic curve, saturation point, composite error, etc., meeting international and domestic standards such as IEC60044, IEC61869,IEEE C57.13, GB 1208, etc.
High precision measurement: Advanced synchronous sampling and digital signal processing technology are adopted to ensure that the measurement of ratio and angle error reaches 0.05 level or higher accuracy, providing reliable data for energy metering and relay protection.
2) Excellent intelligence and efficiency
Powerful built-in power supply: Integrated with a high-power adjustable power supply, all CT/PT tests can be completed without the need for external converters/boosters, greatly simplifying on-site wiring and improving work efficiency.
Intuitive and easy-to-use operation: Embedded computer, equipped with a large-sized color touch screen and a graphical guidance interface, making the operation simple and intuitive.
Data management expert: With massive storage space, it can save complete test data and waveforms. It can be connected to a laptop via Ethernet for easy data tracing and analysis.
