Megger CFL510G- Handheld Time Domain Reflectometer

Description

The Megger CFL510G (1001-790) is a handheld, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m/0.3 ft. and a 5 km/15,000 ft. maximum range depending on velocity factor selected and cable type. Four output impedances (25, 50, 75, and 100 ohms) are available and a velocity factor between 0.2 and 0.99 will meet any cable test requirements.
The CFL510G has a simple selection option which, together with a four-way control switch, offers an intuitive operation for the user.
Applications
The CFL510G is primarily designed for linemen in both the communication and power industries. Specific capabilities include:

Specific line activities identified by this unit include:
Bridge taps and splices n Presence of water in the cable
Opens in tip, ring, or sheath
Shorts between tip, ring, and/or sheath
Capacitive networks
Load coils
Wet splices and high-resistance splices
CATV/Cellular
The CFL510G is ideal for testing the physical integrity of cables within a network. The unit is also capable of locating illegal cable taps.
Specific cable conditions identified include:
Bends or crimps in the cable
Cuts or shorts in the cable
Taps and splits
Water saturation
Power
The CFL510G is an ideal tool for identifying faults on secondary power cables. This unit identifies:
Burnouts in aluminum conductors
Good splices, wet splices, and high-resistance splices
