ModelCRT 8

Cable Route Tracer CRT8 is an essential item in the kit for fault location of underground power and telecom cable network.

It is a powerful audio frequency system that can be effectively used for various unique functions such as route tracing of any metallic cable, depth measurement, live loaded cable tracing and ground survey of underground utilities.

The system is capable to trace route of underground cable maximum 10km, and find out the depth up to 5 meter, by triangulation method. This method is found to give more accurate results in presence of other metallic utilities in close proximity.

The system is accurately identifying the wanted cable from the bunch of cables in communication network.

The system can be used to trace route of loaded live cable with the help of receiver unit and search coil in passive mode.

It is also use to carry out ground survey and metallic pipe route tracing in inductive mode effectively.

Surge Wave Receiver SLE90 is a highly sensitive equipment to exactly locate the fault point in a short time. It can be used on low, medium and high voltage power networks effectively.

The success of locating exact fault point on the underground cable depends on the search carried out on the lay of the cable. This calls for an indication to guide the operator to walk precisely on the cable route. The magnetic channel in dual LCD display indicates the strength of magnetic field on the ground surface.

This helps the operator to reach the fault point in a short time. The acoustic sound is available at the fault point only.
The ambient noise picked up by the ground microphone gives problem during pin-pointing the cable fault was avoid using mute operation.

Surge wave receiver offers the facility to opening the acoustic window for a short time at the arrival of magnetic signal and displays both magnetic and acoustic signal levels on dual LCD display. This offers noise free- operation and the fault is pin-pointed in short time.

It is used to pin-point underground cable faults in transmission and distribution power cable network in acoustic mode with the help of suitable surge tester.

Sheath Fault Tester SFL1 is a powerful system. It is an intact sheath of a plastic insulated medium, high or extra high voltage cable is the prerequisite for the avoidance of water ingress and subsequent cable faults. Different test can be carried using sheath fault locator.

Sheath/earth faults is develop in any type of underground cable network such as low, medium, high voltage power cables or unshielded multi core control cables.

It can be a manufacturing defect or can be caused by

Application

improper handling during laying / external damage /any other reason due to which the metallic armor or cores develop leakage with the mass of earth. These faults can remain undetected for longtime as they do not hamper the working of the cable. It develops into a fully fledged fault over a period of time.

That can successfully locate sheath/earth faults on any type of cable.
It offers different modes such as DC test / HV Test, Burning, pre-location and pin-pointing.

It is use to Conditioning / DC Test / Burn, Pre-locate and Pin-point sheath faults in underground extra high voltage power cable transmission networks.

Description

Cable Fault Locating System COMPAC 32 is prime system to provide quick, effective, accurate and safe fault location. Specifically designed for service, industrial and power utility companies. It is a multi functional system in a trolley mounting design. The HV surge tester, DC High voltage test set, Arc reflection and Burn / Proof test is given for cable fault location of short circuit, open circuit, high resistance, and intermittent and sheath faults.

Pre-location

After identifying the type of fault, pre-location of fault can be determined using the latest pre-location methods such TDR, SIM, ICM, MIM and Decay is provided in this system.

TDR Mode

A narrow electromagnetic pulse with a fast rise time is sent in the cable that reflects back from the fault point /far end where the impedance was change. The VOP for each cable depending on the cable dielectric material is set. The distance to the fault is then computed automatically and displayed on pre-locator.

ICM Mode

It is a current transient analysis method of pre-location of fault. During a breakdown or flashover at the fault, transient's waves are generated that oscillate back to the source end which is utilized through a linear current coupler and store and displayed on pre-locator.

SIM Mode

It is a arc stabilizing mode, faults are stabilized by creating a temporary arc at the fault point through an arc reflection filter and reduce the resistance value of fault as short circuit, and displayed on pre-locator with reference graph.

Decay Mode

It is a voltage transient analysis method of pre-location of fault. Using DC voltage, at a fault point voltage transients are generate that oscillate back to the source end which is utilized through a voltage divider coupler and store and displayed on pre-locator.
