Megger,Reliable cable identification for de-energised and energised cables Right cable. Right phase. Zero doubt. Cable, phase, and live cable identification ■ Fits your network Up to 30 km cables, clamps for large cross-sections and tight cabinets ■ Proven method, clear decision Directional DC-pulse, odd-one-out criterion Cable stays always grounded

Reliable cable selection for de-energised & energised cables For utilities, contractors, rail operators, and industrial sites that need to work safely and efficiently on power cables, the Megger DCI3 is a compact, all-weather cable and phase identification system that delivers reliable results on both de-energised and live cables – in one unit. DCI3 combines Megger’s proven DC impulse method with new three-phase capability, extended range (up to 30 km), and unique passive/flexible clamps option. This makes identification faster, safer, and possible in more challenging environments – without compromising...

Application areas Renewables (Solar, Wind, Hydro) Transportation (Airport, Railway) Safety – reliable cable and phase identification with grounded cable Certainty – identification of the correct cable (odd-one-out method) Performance – accurate identification with cable lengths up to 30 km

DC pulse method - the most reliable method for cable identification ■ Signal travels only over galvanic connections ■ Has the same amplitude everywhere ■ Allows for direction identification ■ Works for all cable system configurations APPLICATION EXAMPLE: 3-phase cable identification mode L2 Clear identification criteria:

APPLICATION EXAMPLE: Twisted-field method for multi-core cable ■ DC pulse injected into 2 twisted cores ■ Sharp positive maximum on injected core and negative maximum ■ No signal on uninjected conductors APPLICATION EXAMPLE: Identification on energised LV cable Identify cables and phases under voltage, up to 440 V where required. Works with twisted-field

Phase identification – stay grounded, stay safe At the substation end, passive clamps verify the correct phase while the earth/short remains connected. The PI signal is injected at the joint bay, enabling reliable identification even over long cable runs of up to 30 km. The transmitter periodically generates alternating current, which creates a magnetic field around the conductor. This magnetic field induces current in the receiver clamp, which charges the clamp. Once this process is complete, the clamp sends a response back to the DCI3 generator. DCI3 decodes the response and displays phase...

Passive clamps (standard accessories) ■ Effortlessly handle cables of up to 30 km ■ Inner diameter of 50 mm ■ Fully passive clamps (without internal battery): no power supply needed Flexible active clamps (optional) ■ ■ ■ ■ ■ Application range: 15+ km Inner diameter of 150 mm For cables with large cross-sections For narrow switchgear cabinets Power supply e.g. via power bank (USB-C)
