An in-depth look at transformer isolation. Electrical isolation is necessary to protect circuits, equipment, and people from shocks and short circuits, as well as to make accurate measurements. Isolation transformers are one way to go. Introduction Electrical isolation is necessary to protect circui... read more
There are two main factors that determine the safety characteristics of the isolation transformer. 1. The secondary line of the isolation transformer is not connected to the earth. First of all, it is generally understood that the power supply system in China generally uses a three-phase four-wire s... read more
Traditional single-phase power wiring consists of a hot wire, a neutral wire, and a ground wire. When multiple, physically separated devices share a common power line, it is possible to create ground loops due to devices having different ground potentials. These ground loops are especially problemat... read more
The same is that all power transformers have iron cores as magnetic circuits and windings for circuits. The biggest difference is between "oil type" and "dry type". In other words, the cooling medium of the two is different. The former uses transformer oil (and other oils such as β oil) as the cooli... read more
The advantages and disadvantages of dry-type transformers and oil-immersed transformers and their differences 1. The advantages and disadvantages of dry-type transformers and oil-immersed transformers: (1) Dry change is more expensive than oil. (2) In terms of capacity, large-capacity oil becomes mo... read more
