Megger CFL510G Time Domain Reflectometer

The Megger CFL 510G Time Domain Reflectometer is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1m/0.3ft and a 5km/15,000ft maximum range depending on velocity factor selected and cable type.

Four output impedances (25, 50, 75, and 100Ω) 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.

This CFL510G is primarily designed for linemen in both the communication and power industries. Specific capabilities include:

Telephony: Provides fast and accurate results when uncovering transmission related problems. Designed to be carried on a linesman’s belt and used in the first line of defense when diagnosing and locating cable faults. Specific line activities by this unit are:

• Bridge taps and splices
• 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: 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: 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
• Shorts between phases
