Do you know how a DR or IDR works? In this video, we will show you how an IDR works in practice, showing how an DR acts on current leaks with a current difference between the phases or phase and neutral. The DR has a transformer that detects a current difference between the circuit cables, which is why it is called a residual differential device. Every electrician needs to know how an IDR works and how to apply it correctly in an electrical installation according to the NBRR5410 standard, which is the standard for low-voltage electrical installations. The vast majority are residential electrical installations. But it is also applied in electrical installations in stores, businesses, factories, that is, for electrical installations in buildings in general. @This video was made in partnership with @ohmicresistoresereostatos1030 TAKE ADVANTAGE!!!
