CURRENT TRANSFORMER SYSTEM INCLUDING STRUCTURE OF SENSOR CT AND STRUCTURE OF GENERATOR CT MOUNTED IN PARALLEL ON ELECTRIC POWER LINE, AND INTEGRATED WIRELESS COMMUNICATION SYSTEM MONITERING THE SAME

摘要

PURPOSE: A current transformer system in which a sensor computed topography (CT) and a power generating CT are separately installed in parallel on a line and an integrated wireless communications system managing the same are provided to use a separable power generating CT as a main power source, thereby independently performing power supply. CONSTITUTION: A sensor CT (200) is installed in a power transmission and distribution line in an attachable and detachable manner. A power generating CT (300) installed on the power transmission and distribution line in an attachable and detachable manner generates power using an electromagnetic induction method. A microprocessor (400) controls the sensor CT and the power generating CT. A current sensing managing module (420) outputs a current signal detected through the sensor CT. A power generation managing module (430) transforms an induced voltage generated in the power generating CT into necessary power. A main CPU (440) determines whether an abnormal current exists or not after comparing a sensing current value and a reference current value.
