Abstract: PURPOSE: An electricity quality control device, a method thereof, and a power usage analysis device thereof are provided to handle power quality by informing a manager of the sensed information in real time. CONSTITUTION: A sensor(100,102,104,106,108) senses the state of a power line. A sensing part(110,112,114,116,118) generates sensing information by collecting information from the sensor. An inner temperature sensor senses self inner temperature compared to the sensing information. A data recorder(180) stores the sensing information. A controller(150) disconnects power inputted to a load according to the sensing information. The controller protects saved information by supplying a disconnection command which disconnects the sensing information and power. A switch part disconnects at least one connection between the data recorder and the load according to the disconnection command.
