Transformer testing Transformer diagnostic measurement is necessary to verify that the transformer operation condition and its efficiency are in accordance with standards. Nankee knows how critical it is to test transformers for best performance as well as what common things you should be testing for.
An insulation resistance test of electrical transformers must also be done, along with temperature thermographic survey. IR testing provides insight into the state of insulation in a transformer. A low value for insulation resistance can indicate possible faults or aging, which makes the equipment prone to problems and failure. With insulation resistance testing, you are able to get ahead of potential issues and avoid expensive repairs or replacements.
The provision of TTR (Turns ratio test) is an essential part of transformer testing. RATIO TESTING Ratio tests determine whether or not the transformer is performing to specifications. You can test the windings in the transformer by comparing to see if it stops at about 10 or so % of its rated turns ratio. This test is very important to us in identifying any future faults and optimizing the performance.
While testing with an electrical transformer there are some common problems you will need to avoid for the best results. Problems to watch out for One common problem to look for is winding faults. Broken insulation, short circuit, and mechanical damage can cause the winding fault. (3) Test fully the transformer windings so that all faults present are found in time to prevent additional damage being done to the transformer.
Core defects are one of the other things generally to keep in mind during transformer testing. Central problems may develop if the fan is overheating, vibrating too much, has not been maintained properly or tested for leaks. The root causes can result in transformers not performing optimally and efficiently. The condition of the transformer core can be known by testing, and possible problems could be addressed to avoid continued damage.
Aside from winding and core problems, one should also pay attention to oil contamination within transformers. The presence of oil can be attributed to water entering the transformer, accumulation of dirt, and aging of the transformer oil. Dirty oil is a source of poor insulation and may lead to failures. Performing transformer oil test for contamination and regular maintenance can help you avoid problems associated with contaminated oil and maximize your transformers performance.
