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.
