Techno Instrumentation (India) Pvt. Ltd.

Digipoint:-

• Magnetic and Acoustic signal strength through bar graph and digits on LCD.
• Coincidence figure (Time delay method) indicates the relative distance to the fault in milliseconds (ms) on LCD.
• LCD screen with backlight feature for night.
• Background noise reduction and noise immunity.
• Built to withstand rugged field conditions with high grade acoustic and magnetic sensors.
• Automatic mute feature to activate while in motion (during pick up of receiver)
• Easy, fast and accurate pinpointing.

Description
It is used with a Surge Generator to determine the exact position of faults in underground power cables.

Pinpointing the exact location of the fault
The surge generated by the surge generator will create an acoustic signal at the fault point. The Digipoint displays the strength of that signal through strength bars and digits on an LCD screen. The headphones help users to hear the sound generated.

Route indication of cable under test
It indicates the route of the cable under test by sensing and amplifying the electromagnetic signals produced at the time of surging and displays the magnetic strength of those signals through strength bars and digits on an LCD screen.

Coincidence Figure
Pinpointing the exact location of faults in cables which are laid inside pipe is very difficult because the air inside the pipe will lead to echo of sound which is generated at the fault point, leading to sound/acoustic signal of strength similar to the fault point at different parts of the cable, hence to pinpoint the exact location of fault in these conditions we use the coincidence feature of the Digipoint, which gives the distance to the fault in milliseconds with respect to your position.
