The essence of the touch current of electronic products to the ground is the current that flows to the earth through the human body by releasing charge from the Y capacitor that inhibits EMI interference.Y capacitance directly determines the size of the contact current.How to measure the contact current reasonably and effectively and determine the grade of electrical energy source is a necessary step in the safety design of electronic products.
