Portable stand-alone cable fault location unit for LV cable installations

• Toolbox philosophy: Identification, prelocation, pinpointing and conversion of faults all in one unit
• Safety interlocks for monitoring of station earth and touch potentials (F-U), as well as earth connections (F-Ohm)
• Fully automatic operation of all modes via motorised switching
• Software-based user interface with single “turn & click” rotary knob control
• ICEplus transient prelocation method for normal unbranched LV cables as well as for branched LV networks
• DC test (DC hi-pot) and burning up to 5 kV, surging (thumping) up to 4 kV, delivers 1000 J

The SPG5-1000-1 is a comprehensive all-in-one-box fault locating solution, tailored for testing, identifying, converting, prelocating, and pinpointing faults in low-voltage cable installations. It effectively handles a wide variety of cable faults: from flashing and non-flashing to high and low resistance, intermittent, main insulation, and sheath faults.

Prioritising user convenience, the SPG5-1000-1 is fully automated and features an intuitive software interface, eliminating most user interventions known from manual analogue instruments. The controller actuates motorised switches so that the unit auto-adjusts to the correct settings based on user input. Simplifying the operation further, a single “turn and click” rotary knob ensures easy accessibility for users of all experience levels.

Utilising the integrated ICEplus method for HV prelocation, the SPG5-1000-1 accurately and precisely locates faults in both unbranched point-to-point low-voltage cables and branched low-voltage networks with T- or Y-joints. ICEplus is a transient prelocation method that evaluates the oscillating current component of a propagating travelling wave which was previously created by capacitor discharge into the cable. Notably, unlike TDR and ARM, this method is unaffected by common issues of attenuation and reflections at T- or Y-junctions, ensuring consistent prelocation regardless of the network’s configuration.
