Fire Prevention Overcurrent Warning Outlet with using the Induced Current of the through Type CT

Domestic and outside the metal bimetal way electrical fire caused by the over-current protection of the power outlet, circuit switching system, precise control over current methods are used by the MCU. However, these methods have a situation overcurrent flowing through direct use or because the wires are exposed to secondary smoke and damage due to the precise control method is difficult to commercialization of the product price increases. In this paper, using a secondary induced current using a feed-through current transformer is not directly controlled in the way that the wire to solve the problem is to prevent an overcurrent from flowing to the problem for the second fire, and damage to the product. In addition, overcurrent warning circuit was implemented using LED and buzzer to whether the overcurrent occurs when the user"s electrical outlet easily.
