DIAGNOSTIC DEVICE FOR PIPE WORN-OUT STATE

摘要

A diagnostic device for pipe worn-out state comprises two coils with a ferro-core and two current transformers, primary windings of which are in series connected to coil windings, resistors are connected to secondary windings, one ends of resistors are united, the other ends are connected to a measuring device; a power source is in parallel connected to the coils outputs. Due to application of a differential method, the diagnostic device provides high accuracy of detection of pipe worn-out state.
