Introduction

This instrument is the first to use industrial embedded computer platform. The whole system consists of three parts: failure test, path finding and measurement, precise point location. It is lithium-powered, portable, and easy to operate. Various faults of power cables with different voltage level, cross section, medium and material, including open circuit, short circuit, low resistance, high resistance leakage, high impedance fault flashover.

• Management: cable laying path distribution diagram. Detailed file information in user ‘s management area, including:  cable distribution diagram, number, starting position, depth and time of laying, cable media, joint position, maintenance records, failure causes, test report, cable test records and other information.

• Radio wave propagation speed could be measured in any cable length of which is known. Trend and burial depth of cable could be measured.
