Abstract

Disclosed herein is a probe for measuring voltage/current of a low voltage power distribution cable. A probe has a body having a first opening and a first recess and made of an insulating material. A lower core is inserted into the first recess of the body, and a coil is wound around an insulating material installed at the lower core for detecting an induction current. A capacitor and a resistor are connected between output lines extended from the coil so as to filter out noise components, and a ground line is electrically connected to one end of the lower core. A voltage detection terminal is electrically connected to the low voltage power distribution cable for detecting voltage applied to the low voltage power distribution cable. A voltage output line is used for outputting the detected voltage. A connector is connected to output sides of the output lines extended from the coil, the ground line and the voltage output line. An end plate is attached to the body for covering the first recess and provided with a second opening and a second recess. A top cover is mounted to the top surfaces of the body and the end plate by nuts interlocked with a fixed bolt fixedly mounted to the body and a movable bolt. An upper core is inserted in the top cover to be opposite to the lower core installed in the body.
