1. ProductsOverview

YSB391Voltage Transformer Field TesterIt is a field testing instrument designed by our company to reduce the workload of on-site electromagnetic voltage transformer calibration. The instrument has the ability to verify the actual error of the voltage transformer under high voltage operation at low voltage conditions. can cover10kV/100VThe10kV//100V/The35kV/100VThe35kV//100V/The110kV//100V/The220kV//100V/Measurement of Variable Ratio Electromagnetic Voltage Transformers. The instrument introduced some new ideas and adopted some new technologies in its design. For example, there are platform technologies, voltage simulation loads, internal high-precision voltage transformers, and self boosting power supplies. Make users feel more convenient, fast, and efficient when using the instrument.

IIFeatures

1、The instrument has added dual windingsPTThe transformer testing function does not require an external load box during testing and is operated using a touch screen.

2TheYSB391Voltage Transformer Field TesterThe internal standard for self boosting voltage transformers with variable ratios achieves an accuracy level of0.05Level, can be in1200Vand2400VAccurately calibrate the error of power voltage transformers under voltage.

3、The instrument uses simulation load technology in the measurement of electromagnetic voltage transformers, which can calculate the load error of the voltage transformer under rated load and lower limit load conditions. Therefore, a voltage load box can be omitted during the calibration of electromagnetic voltage transformers.

4、The accuracy level of the internal transformer calibrator part of the instrument is2Grade.

5、This instrument has the function of automatic sampling of regulatory points, making it convenient and fast for users to conduct regulatory measurements.

6、The instrument has an internal power source output, automatic boost, and excellent protection performance.

7、This instrument adopts universal platform technology, where users can easily access useful information such as previous measurement data, wiring diagrams of various measurement objects, etc. Directly provide measurement values, rounding values, error curves, etc. for each point. Automatically judge the measurement results. The intelligence level of the instrument has been further improved.
