KDHG-220P Variable Frequency Transformer Characteristics Comprehensive Tester
Efficient and accurate power equipment testing solution
Application Applications
Power system maintenance and overhaul
Provide comprehensive performance evaluation for current transformers (CT) and voltage transformers (PT) in substations, including parameter testing of volt ampere characteristics, transformation ratio, polarity, etc., to ensure the stable operation of the power system.
Suitable for regular inspection and maintenance of various protection, metering, TP CT, and electromagnetic unit PTs, improving the safety and reliability of the power grid.
New equipment acceptance and debugging
When constructing or upgrading power facilities, it is used to conduct detailed pre factory testing on newly installed CT and PT to ensure compliance with national and international standards (such as GB20840.1, IEC60044-1).
Provide accurate error curve analysis to help engineers determine whether the equipment meets design specifications and ensure the quality and performance of new equipment.
Research and Education
As a teaching and research tool in universities and research institutions, it is used for experimental courses and scientific research projects in electrical engineering majors to help students and researchers gain a deeper understanding of the working principles and testing methods of transformers.
Support secondary winding resistance measurement, AC load testing, and other functions to meet the detailed research needs of transformer characteristics in laboratory environments.
industrial applications
In industrial production environments, in order to ensure the safe operation of large electrical equipment, the status of transformers is regularly monitored to prevent potential failures and reduce the risk of power outages.
The lightweight design is easy to carry to the site for use, especially suitable for scenarios that require frequent mobile operations, such as equipment testing in remote locations such as wind farms and hydropower stations.
It not only meets the test requirements of excitation characteristics (i.e., volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and Angle difference of various CTS (such as protection type, metering type, TP type), but also can be used for the test of excitation characteristics, transformation ratio, polarity and secondary winding resistance of various PT electromagnetic units.
The device adopts high-performance DSP and ARM manufacturing technology to ensure stable and reliable performance, complete functions, high degree of automation, high test efficiency, and is a professional test instrument for transformers in the power industry.
Only a simple digital setting is required: set the rated parameters of the transformer. The instrument will automatically record the data of the whole process, and automatically calculate and display the ratio polarity, volt-ampere characteristic curve, etc., eliminating the tedious labor of line change, manual voltage regulation, manual recording, sorting, and curve description.
KDHG-A transformer comprehensive tester is a kind of multifunctional field test instrument specially designed for measuring transformer: volt-ampere characteristics, ratio, polarity, error curve, calculating inflection point and secondary side loop inspection.
