Description
TFL 9 Power Cable Fault Locator is a portable, easy to use
cable fault pre-location instrument. It uses the time domain
reflection (TDR), multiple impulse method (MIM), and Impulse
current method (ICM) on low, medium and high voltage
cables. Its measuring ranges enable pre-location on cable
lengths from 0 m to 64km.
TFL 9 is operated via function keys and touch screen, it is
fully menu guided. This instrument is supplied with
rechargeable lithium cell batteries.
Application
It is used for pre-location of short circuit, open circuit fault distance in TDR mode and low insulation / high resistance / flashing /
intermittent fault in ICM / MIM mode with the help of suitable surge tester in power transmission and distribution network cables.
