Ariadna CI-DE

Identification of De-energised cable

The cable identifier Ariadna CI-DE device allows to identify any type of de-energised cable, in a RELIABLE, SIMPLE and SAFE way.

Specially designed for maintenance tasks involving the handling of electrical cables, it is an effective tool that allows operators to easily and without error identify de-energised cables from other conductors in trenches, manholes, panels…

It doesn’t require calibration before using it, factory calibrated.

MAIN FEATURES

De-energised cable identifier
Single-phase and three-phase cables
Signal injection by Direct connection or Induction clamp
Cable length > 50 km (direct connection)
Induction signal amplitude and polarity detection
Identification sound alert
Operation time > 24 h (level 2)
Rechargeable battery on the transmitter (CI-DE Tx)

MRT-700 CI

Underground cable locator as a cable identifier

The technology used for current injection in underground cable locators must be different from that of cable identifiers for electrical safety. In both cases the injected signal and the electrical circuit are different.

The conventional locators can be fitted with a sensor for pre-identification of the cable using the same injected signal as in the tracer, with a good hit rate in some cases.

MERYTRONIC’s underground cable and pipe locator, MRT-700, can be ordered with a cable identifier for de-energised cables, providing 100% reliable identification. In this case we are talking about two devices in one.

This combined solution is very useful for companies working with underground cables. It is very common to find many cables in the same trench when tracing a line. Which one is the correct? That’s where the MRT-700-CI plays a key role – in addition to tracing the cable, you can identify the line unambiguously, saving a lot of time and avoiding accidents.

2 Pole vertical fuse rail / fuse disconnector for DC

The vertical 2 pole fuse base (BBAV and BBAV-P) is available for sizes: NH 1-1XL-2XL-3L, and current: 160/250/500 A

The vertical 2 pole fuse disconnector (BBCV) is available for sizes: NH 1XL-2XL-3L, and current: 250/500 A

The fuse base version (BBAV-P) provides a front side protection degree (without fuse) of IP20 whereas lateral protection. Adittionally, the fuse disconnector version (BBCV) provides two fuse-holders that allows a very simple and effective way at insertion / extraction of the fuse.

Mounting on the standard 185/370 mm busbar system.

MRT-700 FF

Fault pinpointing on cables and pipes

The MRT-700 (*) device has the functionality of Fault pinpointing on cables and pipes. These faults are caused by the deterioration of the coating on the pipe and damage in the cable isolation, whereby the metal part of the cables and pipes may come into contact with the ground.

By combining the MRT-700 device with the A-frame connected to the receiver, it is possible to identify and locate the exact point of the faults. A special frequency – 8KFF – (Fault Locating Frequency) is injected to perform this detection work. High accuracy (<5 cm)

The MRT-700 allows simultaneous cable route tracing and fault pinpointing.

(*) MRT-700 device must be ordered with integrated Fault Detection Functionality.

Main Features

MRT-700TX, generation of a special 8KFF frequency.
MRT-700RX:
- Developed for fault frequency detection
- 2 display modes: Basic and Advanced (Dual)
- Connector for A-frame
A-frame:
- Sensor for fault detection
- Robust A-frame with 2 pins for measuring voltage drop to earth
