Kehui T-900 Hand-held TDR

The Kehui T-900 Hand-held TDR is a compact and easy-to-use instrument for accurately locating open-circuit and low-impedance faults on metallic cables, using time-domain reflectometry (TDR). In this article, we will discuss the main features and benefits of the Kehui T-900 Hand-held TDR.

Features

The Kehui T-900 Hand-held TDR has several features that make it an excellent tool for locating faults on metallic cables. These features include:

  • Compact and easy-to-use
  • Accurately locates open-circuit and low-impedance faults on metallic cables
  • Calculates the velocity of propagation (VOP) of a known length of cable or measures the length of cable on a drum, where the VOP is known
  • Available in three versions with 8, 16, or 32 km range
  • Digital gain control
  • Data transfer via USB flash memory for analysis on a PC
  • Compares TDR traces from the three phases of a faulty cable, which can be used to identify differences between them, providing another useful aid to fault location

Benefits

The Kehui T-900 Hand-held TDR provides several benefits to those who use it. These benefits include:

  • Accurately locates faults on metallic cables, which is essential for maintenance and repair work
  • Compact and easy-to-use, making it an excellent choice for those who need to locate faults on metallic cables
  • Calculates the velocity of propagation (VOP) of a known length of cable or measures the length of cable on a drum, where the VOP is known
  • Available in three versions with 8, 16, or 32 km range, which provides flexibility for different applications
  • Digital gain control, which allows for accurate measurements
  • Data transfer via USB flash memory for analysis on a PC, which makes it easy to record and analyze data
  • Compares TDR traces from the three phases of a faulty cable, which can be used to identify differences between them, providing another useful aid to fault location

How it Works

The Kehui T-900 Hand-held TDR uses time-domain reflectometry (TDR) to locate faults on metallic cables. TDR works by sending a pulse down the cable and measuring the time it takes for the pulse to reflect back from the fault. The T-900 can calculate the velocity of propagation (VOP) of a known length of cable or measure the length of cable on a drum, where the VOP is known. The unit can also compare TDR traces from the three phases of a faulty cable, which can be used to identify differences between them, providing another useful aid to fault location.
