Underground Power Cable Fault Locating Instruments
Techno established in the year 1981 is leading organization engaged in manufacturing and exporting of different types of power cable fault locating instruments. cable fault locator is used for tracing the route and finding faults in underground cables in several power generation, transmission and regulation applications. As the H.T and L.T cables are bound to develop faults after prolonged usage, our instruments helps in accurate rectification of faults and are based on latest technology.

Our Cable fault locator instruments are far superior to the traditional hit & trial methods that takes a lot of time and energy. Moreover, as the usage of XLPE cables have increased recently, the need for intelligent fault location system has increased as it becomes difficult to even locate and trace these cables.

At TECHNO, we are a combining years of experience with new technology to develop robust solutions for diagnosis, fault location and tracing of underground power networks. We are not only invloved with design and development of solution but also provide expert services when needed.

Inbuilt Reflectometer T-510 with LAPTOP for taking distance to the fault.
Built in ARC Reflection Filter.
Suitable as thumper required for pinpointing of fault.
Compact small design, light weight.
Suitable to operate on mains (220-230/240 VAC, 45Hz up to 60 Hz) or portable generator.

DESCRIPTION

Instrument has been primarily designed to produce high voltage surges for pre-location of under ground cable fault in combination with Reflectometer T-510.

The surges produced help in pinpointing the fault and tracing the route of the cable when used with acoustic DIGIPOINT surge generator generates D.C. high voltage for pressure testing of the underground cables to find out faulty phase and the breakdown voltage with leakage current.

It can also be used as limited burn down instrument.

Reflectometer T-510
Pulse Echo, Impulse Current & ARC Reflection Method.
10 Arc graphs + 1 reference graph for accurate & certain fault distance.
Five waveforms for comparison.
Easy to use Cursor. Large graphs storage capacity.
Online support for experts reviews the fault graphs.
Compact small, light weight design.
Suitable to operate on mains (220-230/240 VAC, 45Hz up to 60 Hz) or portable generator.

PRODUCT DESCRIPTION

Reflectometer T510 is a Laptop based Digital Time Domain Reflectometer for pre-location of faults in power Cables. Its state-of-art technology makes it easy to use and yet most reliable for any fault condition. The interactive graphical user interface makes it easy, for even a layman, to pre-locate the fault distance. Serial Port makes the device extremely flexible.

The device has two working modes namely IMPULSE MODE and PULSE ECHO MODE. Pulse echo mode is useful only for open and shot types of faults. The impulse mode when used with surge generator T-1005, T-1016, T-1020 & T-1032 to pre-locate fault distance of almost all types of faults including open, short and intermittent faults by way of ICM Method.

The software provides a huge storage capacity so that you may use the Reflectometer T-510 test result for future reviews & analysis. The innovative feature of software displays LAST TWO waveforms for comparison purposes. The easy to use cursor makes it simple to pre-locate the fault distance. The VOP (Velocity of Propagation) control makes it easy to precisely pre-locate the fault distance on cables with different velocity of propagation. The test waveforms can be printed as a hardcopy directly from the software. The fault readings can be transferred over INTERNET for further
assistance.

The software is so programmed that it automatically saves all the test results, so that you never miss any important result. All the files are stored on the bases of date and time of the reading taken.

DIGIPOINT
Extremely sensitive acoustic, magnetic sensor.
Coincidence figure readout.
Built to withstand rugged field conditions.
Headphones for acoustic signal.
Proportional signal on large L.C.D.
Screen for magnetic and acoustic indication.
Light weight receiver.
Easy to use.

PRODUCT DESCRIPTION

The DIGIPOINT is an easy to use, dual channel Digital Acoustic Fault Locator, designed by TII. It is used in conjunction with a Surge Generator to determine the exact position of faults in underground power cables. The instrument also indicates the cable by sensing and amplifying the electromagnetic signals produced at the time of surges. The DIGIPOINT consists of two units the Acoustic transducer or pick up and the amplifier unit with head phones.

The unique feature of DIGIPOINT provides a relative distance indicator with digital coincidence figure readout. This feature is very helpful for the operator in pinpointing the exact location of fault.

MURRAYLOOP T-1502

PRODUCT DESCRIPTION

TII developed T-1501 High voltage murray loop employing solid state technologies to give very accurate % distance to the following faults.
Earth Fault.
High resistive cable faults (shunts) (constant leakage).
TII developed T-1501 High voltage murray loop employing solid state technologies to give very accurate % distance to the following faults.
T-1501 is a portable, battery-powered instrument. The above mentioned faults which can not be detected by pulse refection method.
T-1501 operates on the principle of Murray loop & can be used with bride supply D.C. voltage up to 5 K.V.
T-1501 measure the distance of the fault from the point of operation to the point of fault of the total length of cable, via calibrated dial and indicates in%.
T-1501 is not suitable for pre-location of low/high resistance flash over or intermittent faults.
T-510 Refectometer with T-1005, T-1016, T-1020 & T-1032 surge generators is suitable for high resistance or intermittent faults.

Note: For flashing faults Murray Loop is not suitable. Use Reflectometer T-510 for such faults.
