Web1 Mar 2015 · 15. The Dissolved Gas Analysis (DGA) is a chemical test rather than an electrical test. It does not suffer from electrical interference and can be done without de - energization of the transformer. The cost of each DGA is relatively inexpensive. All these factors make DGA a powerful tool in the preventive maintenance of transformer. WebAbstract - Power transformers are key electrical assets in power networks. Their lifetimes are estimated to be around 40 years if they are properly maintained. However, thermal, …
