"Luxfine LCP leakage current prevention device" is a power supply device that prevents leakage current, and electrical devices used by receiving power through this device are safe from leakage current. Leakage current is the current generated by an electrical device outside the normal track, i) the current flowing between the applied live line and the ground, ii) the current flowing between the live line and the neutral line (N), e.g., between the two terminals of the outlet. When a person encounters a conductor of an electrical device, the leakage current flows through the human body and poses a serious threat to the body and life. "Luxfine LCP" allows the human body to safely use electricity by preventing current from flowing even when it encounters the conductor of an electrical device. It allows safe use of electricity even in humid places or when flooded. Existing short circuit breakers are designed to protect the system by operating at leakage currents above 30mA, but the risk of electric shock is always present in sections below 30mA where the short circuit breakers operate normally. In other words, the current between 6 and 30mA also has a significant effect on the body's muscular control and nervous system, leading to secondary accidents or death. Leakage current causes failure, malfunction, life span reduction, fire, etc. of not only the human body but also the electrical equipment used. To prepare for electrical hazards that may occur in the event of a malfunction of a short circuit breaker or in a section below 30mA that is not protected by a short circuit breaker, equipment that can fundamentally block leakage current was developed. The current between the conductor and the ground of the electrical device using this equipment is almost "Zero" amperes. "Luxfine LCP" has built-in functions to drastically reduce the generation of electromagnetic waves that are fatal to the human body and to pre-detect the risk of fire due to aging power lines or de-insulation. In addition, to single-phase 220V, three-phase 380V, products ranging from 300VA to 10kVA are developed as standard models. Commercial and industrial applications with much larger capacity, as well as products with a step-down function of input 220VAC and output 110VAC can be also customized. Applications Places that require a lot of moisture and water, sewage treatment plants, water purification plants, fish farms The expensive old equipment that needs to be overhauled due to leakage current Streetlight pole, signal light pole in areas vulnerable to electric shock or habitually flooded
