Product Details

■Product Overview

This instrument is a diagnostic device that detects potential faults in power lines by capturing abnormal ultrasonic signals and analyzing them via software. It enables the identification of fault‑prone locations and fault types without interrupting power supply. The device operates using an ultrasonic sensor. ( Ultrasonic sensor ) After acquiring abnormal ultrasonic signals , Transferred to the host , At the same time, the host’s built-in analysis software accurately identifies the type and severity of fault symptoms and converts this information into audible signals and waveform outputs, helping inspection personnel promptly detect potential line‑fault hazards. , Preventing the occurrence of catastrophic failures , Avoided unnecessary power outages. , It has enhanced power supply reliability, while also improving the efficiency of inspection personnel and reducing their workload.

■ Features and Benefits

Handheld, non-contact, visualizable, audible, and waveform-displaying detection for energized equipment—without direct contact.

Can be opened to the substation. ( Open-air ) Equipment is subjected to live‑line scanning, enabling the detection and localization of various partial discharges. : Corona discharge, arc discharge, flashover, creepage, wire breakage, arcing, and so on.

Detect and locate insulator flashover on transmission towers, surface tracking at outdoor cable terminations, and partial discharge detection and localization in underground cables. ;

In the handover and preventive testing of power systems, the main transformer and… GIS In partial discharge testing, when this device is used in conjunction with a partial discharge locator, it can distinguish between internal and external discharges; if the discharge is external, it can pinpoint the exact location of the discharge.

Large oil-immersed transformers, dry-type transformers, and GIS During the manufacturer’s factory acceptance tests, when this device is used in conjunction with a partial discharge (PD) tester, any discharge—whether internal or external—cannot be distinguished on the PD tester’s display. By scanning the test specimen with a handheld inspection and localization instrument, the external discharge point can be quickly identified and located; if no external discharge is detected, the discharge is classified as internal.

Leak detection for high-pressure sealed gases and liquids.

300 The megapixel HD camera can easily focus to detect fault locations and capture images of tower markings and faulty equipment.

Embedded GPS The receiver automatically stores coordinate data and provides GPS Navigation functionality for easy querying and saving of inspection paths.

It features temperature and humidity sensing, enabling real-time monitoring of ambient temperature and humidity.
