Oil immersed transformer classification

Oil immersed transformers 1000kVA and above, shall be installed outdoor thermometer type signal, and then the distant signal. 800kVA and above should be installed oil-immersed transformer gas relay and pressure protection device, 800kVA transformer oil-immersed according to the following requirements, in consultation with the manufacturer, but also can be equipped with gas relay. Dry-type transformers shall be specified by the manufacturer, the installation of a temperature measuring device, and more generally for the 630kVA transformer installations. Products classified according to the number of phases to distinguish between single transformer can be divided into three-phase transformers and single phase transformer. In a three-phase power system, the general application of the three-phase transformer, when the oversized transport conditions and subject to the three-phase power system can also be applied consisting of three single-phase transformer transformer group.
