How to ensure the transportation of DC resistance testers?

The transformer DC resistance tester is commonly used to measure the DC resistance of large capacity transformers. It is a high-precision stable current power supply and testing part designed as a whole. The testing process is controlled by a microcomputer and automatically completes stable current ......

Different measurement methods for DC resistance testers

Application of DC Resistance Tester in practical operation

​DC resistance test is an indispensable test item after the transformer is handed over, overhauled and the tap changer is changed. Therefore, it is very important to use a DC resistance tester to test the DC resistance of the transformer. Routine maintenance and good use of the DC resistance tester.......

Inspection and identification methods for transformer on-load tap changer (OLTC) faults

According to statistics, the faults of the on-load voltage regulating switch of the transformer mainly include two aspects: First, the failure of the voltage regulating switch driving mechanism, mainly including the linkage of the electric mechanism, water intrusion into the box, oil leakage from th......

Common faults of High-voltage Test Transformers(AC Hipot Tester)

High voltage test transformers can also experience faults in normal use, but small faults such as short circuits can actually be avoided. Now, let's introduce in detail the common faults and solutions of high-voltage test transformers.
