Product Q&A

Q:What is the accuracy of the turns ratio test?

The accuracy varies by voltage range: Class 0.1 for 1-500, Class 0.2 for 500-2000 and 1-100 low voltage, and Class 0.5 for 2000-5000 and 100-500 low voltage.

Q:How long does it take to test one group of data?

The testing speed is fast, with each group of data taking only 10 seconds to complete.

Q:What types of transformers can this instrument test?

It is suitable for single and three-phase power transformers, phase shifting rectifier transformers, Scott transformers, and Inverse Scott transformers.

Q:Does the device support automatic tap changer detection?

Yes, after setting the rated parameters, it can automatically determine the tap changer position and ratio during measurement.

Q:What are the data storage and connectivity options?

It has two USB ports: one for PC control and online measurement, and another for inserting a USB disk to save data in Excel format.
