1. Application
FUOOTECH FTDC-S1 Transformer DC Resistance Test Iinstrument can use Android mobile phone or tablet, pay attention to WeChat official account, Download APP, control software through special software, test data storage and upload, and facilitate access.
This instrument adopts new power supply technology, with many current ranges and wide measuring range. It can automatically select the current according to the load. It is suitable for DC resistance measurement of small and medium-sized transformers and voltage transformers.
2. How Confirm the DC Resistance Measurement is Correct?
Comparing the factory value or factory standard and the previous measured value can help to confirm the measured value is satisfactory or not.
So, note the below points and compare:
● Comparing to original factory measurements
● Comparing to previous field measurements
● Comparing one phase to another
● Industry standard (factory) permits a maximum difference of 0.5% from average of three phase wingdings.
● Field readings may vary slightly more than this due to the many variables. If all readings are within 1% of each other, they are acceptable.
