Do you want to know how to choose and protect a transformer? We have talked several times about the use of transformers here on the channel and shown some precautions that should be taken when using this device. In this video, we will show you how to correctly choose and protect your transformer in a very simple way with a spreadsheet that we will make available for free. Let's talk about the famous 127/220 autotransformer model. It can be used to transform a voltage of 127V into 220V or 220V into 127V. This is an important detail. Give preference to models with this voltage indication of 127/220V in relation to the 110/220 models, this is because 110/220V models are voltage doublers, since according to the indication, one voltage is exactly double the other. So if you use a transformer like this and connect 127V to the primary, you will have 254V in the secondary. If the voltage increases to 130V, you will have 260V in the secondary. If you connect a device that works at 220V to a voltage of 254 or 260V, it may be damaged, so pay close attention to this detail. To choose a transformer, it is important to know the power that your device consumes in W for resistive loads and in VA for other loads. At the beginning of the description, we left a link to a spreadsheet with three ways to obtain the power. Let's see how the spreadsheet works and, with the help of our partner Gerais Elétrica, we will also show you how to set up a safe system with the information obtained. But first, I'm sure this video deserves a like and also deserves to be shared. By doing so, you will be helping Eletricity to create more videos like this one on the channel. Now you have a tool to help you choose your transformer and learned how to set up a safe system for your use. We would like to thank Gilvan from Gerais Elétrica for the partnership that provided knowledge to our subscribers. Gerais Elétrica operates in the commercialization of electrical materials in general, serving the residential, commercial and industrial sectors. Founded in mid-January 2020, it is now one of the largest retail stores in the Metropolitan Region of Belo Horizonte. If you want to know a little more about Gerais Elétrica, we left a link at the beginning of this description. Take the opportunity to subscribe to the channel and activate notifications. Help us reach the 200,000 subscriber mark by December 2021. See you next time! ???? Tune in to #electricity ???? __________________________________________________ ????
