High Voltage Surge Tester - Model SWT 16  Download Catalogue

High Voltage Surge Tester SWT 16 is useful equipment for to pin-point underground power cable fault by acoustic method with a suitable surge receiver. In power cable fault location most of majority faults pin-points test are carried out using a high voltage and high energy surge wave tester. It offers 500 Joules of energy on 4, 8 and 16 kV selectable ranges, which is use on low and medium voltage cable networks effectively. It is also used to pre-locate cable fault distance with the help of suitable pre-locator unit in impulse current (ICM) mode.

Occurrence of cable fault can not be avoided due to many factors. Long outage of a cable from service results in heavy loss of revenue to the power distribution company, production loss to industries as well as unpleasant condition to general. This requires an efficient equipment capable of locating the fault and test cable in minimum possible time and restoring the supply. In power cable fault location the vast majority of pin-pointing and cable test are carried out using a surge wave tester. It is a powerful equipment and offers 1000 Joules energy on 8, 16 and 32 KV ranges, and DC high voltage (high pot) test which allows its use on LT, Medium and HT networks effectively.

Surge Wave Receiver - Model SLE 90  Download Catalogue
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. Surge wave receiver offers the facility to opening the acoustic window for a short 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.

Cable Identification System - Model CI 60S  Download Catalogue
Cable Identification System is an essential item in the kit for fault location of underground power cable network. It consists of Identification Transmitter, Identification Receiver and Identification Tongs. The system is used for identification of wanted cable from the bunch of cables in power cable network. The precise identification of a particular cable from a bunch is a common problem faced by technicians and cable joiners in every day practice. The wrong identification of a power cable can result in catastrophic or fatal results if the cable is cut. This requires the most reliable system having no chance for wrong identification. Cable identification system incorporates all the safety features and gives 100% safe full identification of the wanted cable, and leaving no chance for an accident.

High Voltage Test Instruments - Model HVG  Download Catalogue
The High Voltage Test Set HVG or Di-electric Hi-Pot tester is highly reliable, accurate and rugged tool to check the quality of dielectric strength of the insulation in power cable, capacitors, transformers and many electrical components. This test also called as Dielectric breakdown test The AC/DC Hi-Pot test is extremely important to identify the deterioration in the insulation as early as possible to take corrective measures. The AC/DC Hi-Pot test is an important part and parcel of the electrical safety tests mandated by standards organization worldwide. More than 80 per cent of faults in electrical and electronic systems are due to weak insulation caused by environmental factors such as dirt, grease, temperature stress, humidity, etc that affect the dielectric strength of the insulation material.

Cable Burn Down Instruments - Model CBD 7  Download Catalogue
Cable Burn Down Equipment CBD7 is applied in typical medium and high resistance faults that are beyond the range of applying Pulse Echo equipment for pre-location measurement. A carbon bridge is produced by burning the cable insulation at fault point, which helps in locating the fault distance easily. They are also used for conditioning unstable faults such as ingress of moisture. In case of flame proof cables (such as PE/XLPE) it can be used to dry wet cable faults. It is the most suitable equipment, offering up to 7 kVA energy for above application for any type and grade of HT/LT cable. Burn down process is controlled by selection of voltage range selection and continuous variation with variac.

Sheath Fault Tester - Model SFL 1  Download Catalogue
Sheath/earth faults develop on any type of underground cable network such as low, medium, high voltage power cables or unshielded multi core control cables. These faults can remain undetected for longtime as they do not hamper the working of the cable. It develops into a full fledged fault over a period of time. Earth Fault Tester SFL1 is a powerful system that can successfully locate sheath/earth faults on any type of cable. It offers different modes such as HV Test, Burning, pre-location and pin-pointing.
