Insulation Fault Locator
Locate defective insulation, short circuits, leakage currents, and poor connections in track circuits by tracking an AC signal along rails and cables. Use the operating frequency of an active track circuit, or the included generator when no usable signal is present.

Capabilities
- Signal-tracking principle: the sensor picks up AC signal current in rails or cables
- Acoustic indication with a modulated tone, plus a numerical display of signal level
- Uses the operating frequency of track circuits, trap circuits, automatic train control, or loop detection equipment as the test signal
- Frequency selection by known frequency, up to 30 stored presets, or broadband frequency search
- Finds the strongest test signal and adapts automatically to the signal level
- Frequency-selective operation suits fault finding without disabling the signaling system and in the presence of traction current
- Locates faults inch by inch, including on hidden components
- Included generator mounts to the rail head or web with a permanent magnet
- Lightweight sensor with a telescoping bar for transport and use
- Three-button operation: minus/plus to browse, round button to confirm
- Low-battery indication and automatic shutdown on sensor and generator
Applications
- Installing and checking connections on track circuits and trap circuits
- Rails and sleepers (ties), including leakage between both rails
- Insulated joints and insulated points
- Impedance bonds, S-bonds, and balancing connections
- Track-circuit power supply and output connections
- Heating insulation, earth (ground) cables, and jumper cables
- Cables in track ballast, and track rods and bonds under pavement, asphalt, or concrete
- Loop detection equipment (track loops)
