APPARATUS FOR TESTING SHORT-CIRCUITING AND OVERLOAD

摘要

PURPOSE: An apparatus for testing both of short-circuiting and overload is provided which tests the short-circuiting and overload using commercial power without requiring a separate device. CONSTITUTION: An apparatus tests an object using a power input unit, a protector including a breaker and a switch, and controller for controlling an input power voltage to be converted into a voltage value for test. The apparatus includes a means(53) for selecting the kind of a test, and a load controller(55) for converting the test voltage value into a required current value to apply the current value to the object to be tested according to the current value needed for the selected kind of the test. The apparatus further has a means for short-circuiting the object to which the current value was applied, and a means for measuring and recording test data values including the voltage and current applied to the object and operation time.
