Smart earth leakage circuit breaker

A smart earth leakage circuit breaker, installed on a distribution line through which an electric current flows, configured to measure, by means of a current transformer (CT), a leakage current flowing through the distribution line, and when the measured current exceeds a preset rated sensitivity current, configured to cut off electricity by means of trip operation, the smart earth leakage circuit breaker comprising:

• a measurement unit configured to track and measure, based on measurement information of the CT, a value of the leakage current flowing through the distribution line, wherein the value of the leakage current exceeds an alarm current value set by a microprocessor;
• the microprocessor configured to set conditionality and the alarm current value less than the rated sensitivity current, and when the conditionality is satisfied based on information measured by the measurement unit, configured to issue a warning by means of an alarm unit;
• and
• the alarm unit configured to be operated and controlled by the microprocessor and configured to warn of an abnormal symptom of the distribution line by emitting an alarm to the surrounding area,
• wherein the conditionality set in the microprocessor includes a threshold number of the number of times when the leakage current exceeds the alarm current value through the measurement information of the measurement unit or includes the threshold number and a unit detection period for tracking the threshold number,
• wherein when the set conditionality is satisfied, the microprocessor transmits alarm information to a home Internet of Things (IoT) through wired/wireless communication to issue a warning to the surrounding area by means of the home IoT, and
• wherein the home IoT transmits the alarm information to a set phone number input through Wi-Fi.
