THE APPARATUS AND METHOD TO MEASURE THE QUALITY OF LOW VOLATGE SERVICE CABLE TO THE CUSTOMERS WHILE TRACING AND IDENTIFICATION OF MEDIUM AND LOW VOLTAGE POWER CABLE

摘要

PURPOSE: An apparatus and a method to measure quality of low voltage service cable are provided to prevent breakdown by detecting low-voltage power line in advance. CONSTITUTION: A power line apparatus for measuring quality is connected to the low-voltage power line load side, and generates successively a group of large current pulses. An arc signal generating in the power line is detected. A circuit probe apparatus identifies a connection specification and a path between power devices in driving using current measuring device.
