ARIADNA TRZ Underground Cable Locator

Kementsu has developed an underground cable locator instrument with a double functionality: it locates and identifies a LV or MV cable from the surface. It's working principle is based in two different systems:

Active signal induction with a signal clamp.
Directional Current Pulses (DCP) injection on the cable.

Cable location and cable tracing is very easy combining both systems: the active signal is used to locate a cable. Before tracing the cable, the DCP mode can be enabled by pressing a button. This mode will tell you whether the located cable is the same cable where the transmitter is connected to. DCP mode can be used anytime while tracing a cable just to check that the traced cable is the target one. With this feature you avoid the long process of checking and comparing signal amplitude, cable current, cable depth, etc. in every point where the injected signal appears.

Directional Current Pulses are current pulses whose shape has been designed and patented by Kementsu. DCP’s main feature is that they don’t leak into other cables, appearing only on the cable where they are injected. With this system, the Ariadna TRZ can locate, trace and identify the desired cable where other similar instruments just provide information that must be processed by the user, without being able to conclude whether the located cable is the target one or not.

Directional Current Pulses can be detected both from the surface and in those places where the cable is accessibe, such as distribution boxes, trenches, at the transformer substation, etc.

FEATURES

It locates, traces and identifies live and de-energized cables.
It can detect three different kinds of signals: passive signals (50/60 Hz), active signals induced by the transmitter and Directional Current Pulses.
It can induce two different active frequencies (8 kHz or 33 kHz) for cable location and tracing.
It can work in Peak Mode, Null Mode and combined Peak / Null Mode. The combined Peak / Null Mode is very accurate for cable location.
Arrows indicate the position of the cable, making cable location and tracing very easy.
Two different ways of measuring cable depth: either by pressing a button (depth appears on the display) or using the 45º method.
Current measurement can be used when locating close parallel cables.
By pressing a button, the DCP mode is enabled. Using this mode it is possible to confirm in a quick and accurate way that the located or traced cable is the same one where the transmitter is connected to.
