Connect — Automatic — Inspect

The on field test is very simple, after the connection between TV60 and cable is completed, the operating

software will guide you through the entire process.

Connect: After the necessary inspections and pre-tests are completed, only need few connections about

DAC test.

The Mini CAM is a standalone system for acoustic image measurements and signal analysis. As a standalone system, no additional equipment is needed for basic usage of the device.

This rugged, versatile tool can help you quickly and easily identify a variety of undesirable industrial condi- tions, like electric faults, gas leaks. With pinpoint accuracy the Mini CAM allows you to instantly see audible and ultrasonic noises that are hard to detect, With 128 Digital Microphones, it will help you clearly see what you've been missing.

By adding an optional thermal camera part, the Mini CAM can change functions between acoustic imaging and thermal imaging, making diagnosis more comprehensive and efficient.

When an electric arc occurs, it results in ultrasonic wave element, higher than the audible frequency. There- fore, in noisy environment, ultrasonic wave element can be measured to determine whether or not electric arc have occurred and where they have occurred.

Introduction

Work independently

When used independently, only one test wire is needed to achieve testing of the full length (broken wire), joints, and low impedance fault distance of the power cables.

Principle

It’s based on the radar principle and makes use of the fact that any sudden deviations in the characteristic impedance of a cable reflect part of the energy transmitted into the cable. The degree of reflection is dependent on the magnitude of the deviation in the characteristic impedance, the number of reflections, the cable length and the distance to the fault position.

Work with surge generator (Thumpers)

When combined with a surge generator and suitable separation devices, the WL20 supports multiple HV prelocation methods (e.g., ARM, ICE etc.). Its adaptive trigger technology ensures optimal timing of TDR measurements for most accurate results.
