The Megger Surgeflex 32 (SFX32, formerly Seba KMT / SebaKMT) is a portable cable test and fault location system for low and medium voltage power cables at voltage levels up to 32 kV. It brings together multiple fault location methods in a single mobile unit: the powerful ARM (Arc Reflection Method) for prelocation of high resistance faults up to 32 kV, TDR Teleflex SX technology for locating low resistance faults without high voltage, and 1750 J of surge energy for acoustic pinpointing. Trolley-mounted with large wheels and built for field use, the Surgeflex 32 also includes DC testing up to 32 kV, fault conditioning by short-term burning at all voltage levels, and sheath fault locating.

Fault location methods
Prelocation
The Teleflex SX uses time domain reflectometry (TDR) to measure distance to a fault. Low resistance faults can be located with TDR alone, no high voltage required. For high resistance faults, the powerful ARM (Arc Reflection Method) captures 15 measurements in a single shot at up to 32 kV. The ICE (Impulse Current) method and Decay travelling wave method provide additional prelocation techniques across selectable voltage levels.
Fault conditioning and pinpointing
Short-term burning at all voltage levels (up to 32 kV, 160 mA) converts difficult high resistance faults to low resistance for easier location. For pinpointing, the system delivers 1750 J of surge energy to produce an acoustic signal at the fault position. A receiver such as the digiPHONE+ (optional) picks up the sound at surface level for precise positioning. Sheath testing operates at 0-5 kV with power regulation.
Key features
Teleflex SX with easyGO and Expert modes
The Teleflex SX features a 10.4″ colour touchscreen with control knob. In easyGO mode, the system guides operators step-by-step through the fault location process automatically. Expert mode opens full parameter access for comprehensive fault locating under difficult conditions. An IFL (Intermittent Fault Location) mode is also included. The Teleflex SX is also available as a standalone portable TDR reflectometer.
Portable, field-ready design
The unit is trolley-mounted with large wheels for site use, and connecting cables for earthing, mains, and HV are conveniently accessible at the rear. The enclosure is rated IP65 closed and IP54 open. The system can also be fixed-installed in a cable fault location vehicle.
FAQ
What types of fault can the Surgeflex 32 locate?
The system handles high resistance faults (using ARM), low resistance faults (using TDR), intermittent faults (IFL mode), and sheath faults. Where a stubborn fault resists direct prelocation, burning at up to 32 kV converts it to low resistance for easier identification with TDR.
What is the difference between the Surgeflex 32 and the Surgeflex 15 and 25?
The Surgeflex 15 and 25 are battery-powered portable fault location systems in the same series, with 15 or 25 kV output and 1150 J of surge energy. The Surgeflex 32 reaches 32 kV with 1750 J (optionally 3500 J), giving it the capability to handle higher-voltage medium voltage networks.
What optional accessories are available?
Options include the digiPHONE+ acoustic pinpointing receiver, an audio frequency cable tracer, the ESG NT surge extension to 3500 J (for vehicle installation only), and 4 kV surging at 1200 J.
