Cable test vans and fault locations Systems

BAUR’s cable fault location and diagnostics systems

Would you like to test and assess new installations and existing cable locations efficiently? To rectify issues in the network as quickly as possible? Or offer your clients the maximum security of supply every day through a reliable and stable network?

Then BAUR’s modern cable fault location and diagnostics systems are the

ideal solution for you. Save your and especially your clients’ time and money with modern and efficient technology.

BAUR offers three types of system solutions for one- and three-phase cables: the cable test vans titron and transcable, as well as the Syscompact series.

A system with additional value

Whilst fewer employees carry out more and more work, this doesn’t have to impact the quality of the work: BAUR systems counterbalance this evolution through intelligent software. The operator no longer deals with operating the technology but instead provides the system with the tasks. The system carries out the work in an efficient and reliable manner without limiting the operator’s work or even imposing on him. Flexibility is our highest priority; this means each step suggested by the system can be selected freely.

titron

State of the art

The titron automatic cable fault location system is characterised by efficient technology and intuitive operation. The new generation high-performance system is based on state-of-the-art technology and provides efficient, safe and reliable cable fault location, cable testing and cable diagnostics with its soft- ware support.

A system with exclusive features

The completely new titron concept makes your work easier. With an intuitive user interface and automated sequences, titron ensures reliable and quick cable fault location. A package full of features that saves time and money.

New intuitive operational concept

BAUR GeoBase Map: The unique GPS-supported combination of road maps with the cable route and the BAUR cable database shows the current location, the cable route and the fault locations. The selection of maps can be extended at any time.

The Cable Mapping Technology (CMT) provides an overview of the cable accessories and faults proportional to the cable length. All data on the cable route such as geographic position, voltage level, joints, measured values, etc. are automatically saved and can be accessed at any time. Clearly arranged and precise measurement logs can be quickly and easily com- piled with individual comments and figures of the traces.

Smart Cable Fault Location Guide

Our intelligent Smart Cable Fault Location Guide software leads you to the cable fault step-by-step. In this process, special, experience-based algorithms con- tinuously analyse the current measurement results which are used to generate optimum recommendations regarding the further procedure required to quickly and efficiently locate the cable fault.

The voltage wizard recommends voltage values that comply with the standards according to the present cable data, the type of fault and the application. A user-specific adjustment can be carried out at any time.

With the cable mapping tool and its clear graphic display, the automatic fault analysis provides you with a better overview and a direct, detailed comparison of the trace of the cable. The system automatically adjusts the required measurement parameters and marks the cable end and the fault position.

TransCable

Proven quality

The transcable is an automatic or semi-automatic, one- or three-phase cable fault location system. Through the modular design, the individually functional modules work independently from one another. This makes it possible to modify or expand the transcable system without any problems at any time.

The functional scope of the transcable is very versatile. In addition to the required testing technology for cable fault location and cable testing, meaningful software-supported cable condition assessments with dissipation factor and partial discharge measurements are possible due to the VLF truesinus® based smart testing technology.

Universal application

Due to its modular design, the transcable system enables the integration of multiple options: e.g. the integration of a PHG VLF testing system but also surge generators up to 60/100 kV or DC voltage testing up to 110 kV. Therefore, the system is universally applicable, even on HV cables and offshore.

The analysis serves to ascertain the fault characteristics and determines the further procedure in the fault loca- tion, the selection of methods and also the voltages. Insulation resistance measurement is used to determine the faulty phase and the type of fault. Voltage withstand testing and breakdown detection is used for testing the electric strength of the cable insulation. Cable sheath testing is used to determine external cable damage (sheath faults).

Testing and diagnostics make it possible to determine the quality of the cable. They also help in a preventive manner by using suitable measures to maintain the highest quality of the cable installation. Testing: DC, VLF sine and square wave voltage are available depending on the system configuration. A partial discharge diagnosis is used to determine possible fault locations in cables and fixtures before they lead to failure. This makes it possible to rectify the problem in a timely manner and prevent any subsequent damage resulting from uncontrolled failure. The tan delta dissipation factor measurement is used to determine the ageing condition of a cable. Possible exchange activities can be controlled in a targeted manner in the framework of professional asset management.

The objective of the pre-location is to determine the fault position as precisely as possible to keep the subsequent pinpointing activities as brief and efficient as possible.
TDR: Time Domain Reflectometry is used to locate low-resis- tive faults and cable interruptions and to determine the cable length.
SIM/MIM: The Secondary / Multiple Impulse Method is the best and most precise cable fault pre-location method with the highest level of efficiency. High-resistive and intermittent faults are triggered by one single HV pulse, then the fault distance is measured accurately multiple times with the TDR technology and automatically analysed.
DC-SIM/MIM: Secondary/multiple impulse method in DC mode for pinpointing intermittent faults; voltage is applied to the cable; at the breakdown a SIM/MIM measurement is automatically and simultaneously carried out.
Conditioning-SIM/MIM: The fault conditioning with SIM/MIM measurement has been developed specifically for wet faults that are difficult to locate. First, the fault is conditioned with surge voltage, then a SIM/MIM measurement is carried out.
Decay: Voltage-coupled decay method for pinpointing intermittent cable faults; the oscillating reflected waves are automatically analysed to determine the fault distance.
ICM: The Impulse Current Method is used to locate high- resistive and intermittent cable faults. The fault distance is determined by analysing the impulse current diagrams.
DC-ICM: The Impulse Current Method is used in DC mode to locate flashover faults. Measurement mode with envelope curve display for inter- mittent faults; reflection measurements are carried out continuously. In this process, even small changes to im- pedance are made visible by means of an envelope curve and are automatically saved.

As precise as pre-location is, it is not able to detect or recognise the existing deviations in the ground. These can only be corrected by precise pinpointing.
Cable route tracing: used to precisely determine the ca- ble route; precise positioning is essential, particularly with unknown or imprecise cable routes, and saves both time and money. Acoustic pinpointing: the most common method used to pinpoint the location of high-resistive and intermittent flash- over faults; the high-voltage flashovers at the fault generate acoustic and electromagnetic signals that are used for locating the fault position.
Step voltage method: used to pinpoint the location of cable sheath faults; a voltage drop is generated at the fault which can be pinpointed using an earth rod and a universal locator (UL 30). Twist method or minimum turbidity method: applied when pinpointing short circuits depending on the cable type; in this process, the disturbance in the otherwise homogeneous mag- netic field that is caused by the fault is measured and precisely located.
