A product of the most recent generation, the Transformer Winding Resistance Tester is best suited for measuring the DC resistance of the three-phase winding of a large-capacity transformer. It measures the DC resistance of Y-transformers. It can simultaneously measure the DC resistance of the three-phase winding.
It is not necessary to discharge the on-load voltage regulating transformer; instead, the tapping switch only needs to be adjusted. The working time and labour intensity are significantly reduced because the measuring time is one-third that of the conventional single-phase measurement.
The operation is straightforward and simple to understand because of the large-screen LCD and graphical user interfaces that are included.
Additionally, it has a big capacity non-volatile memory and a panel style printer, making it simple to save and print out measurement findings. It is the most suitable option for the on-site measurement of transformer DC resistance because of its excellent data testing stability, speed, and perfect reproducibility.
The Global Transformer Winding Resistance Tester market accountedfor $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
It is intended to test the winding resistance of transformers, inductors, generators, and motor windings, as well as tap changers, busbar contacts, and power cables, among other things.
For Highly Inductive things like 765kV, 400kV, and 220kV, it is specifically made. This is the only native TWRM that provides extremely quick readings for 3Phase Star-Delta Transformers of any configuration.
Open circuit with built-in In order to take quick measurements, the transformer's core must be saturated by the DC supply voltage. Such transformers' back emf is carefully absorbed. For the user's safety, a discharge indication is offered on the front panel if the measurement of the current through the winding is disturbed or stopped.
One of the most frequent reasons for transformer failure is the deterioration of the transformer's insulation resistance. Replacing a failed transformer in an electrical system can be expensive and involve a significant amount of downtime.
Transformer resistance testing may tell you a lot about a transformer by measuring its winding resistance from one HV transformer bushing to another. Subtle issues can be found in addition to the obvious faulty transformer winding (i.e., an open winding or shorted turn).
The on-load tap changer (OLTC), the off-load ratio adjusting switch (DETC), and numerous welded and mechanical connections are all places where the DC current travels in addition to the winding. Therefore, the usage of transformer resistance test tools can be used to confirm the integrity of all of these components.
