    Underground cable faults cannot be avoided due to many factors such as road widening, infrastructure improvement, digging carried out for repairs of other underground utilities etc.

    These faults generally take long time to detect and hence long time to repair the damaged cables and restore the power supply. Long outages cause heavy production loss to industries, revenue loss to power distribution companies and inconvenience to general public. This calls for quick fault location and restoration of power supply in minimum possible time.

    An ordinary fault locating kit comprising of diagnosis set and pin-pointing equipment can take long time to locate fault point. SCOPE offers pre-locator instruments that can give the fault distance to help the operator for reaching the spot quickly and pin-pointing the fault in a short time.

    ”XC 2100E, a Fault Location System based on principle of travelling wave detection is the solution to above problem. It can detect not only permanent fault, but also transient fault within one tower span accuracy (with best accuracy of ±50 meters). It is a kind of Line Monitor for continuous monitoring of transmission lines and gets triggered whenever travelling waves are generated on line due to switching, lightening or fault.

    There are various methods employed for fault location detection. However the most suitable is Double End Method in which XC 100E are installed on both ends of the line, and are time synchronised by built-in GPS Module.

    The data from both Units is brought to a Master Station where the Master Station Software XCF 2100E is installed. It automatically calculates the distance of fault from each end of line. Each XC 100E is capable of monitoring up-to 8 lines and the Master Station Software is capable of handling large no. of lines in a network.

    Features

    • TWFL system is free from influence of following factors which aff ect fault location accuracy of impedance based measurement methods like:
      • Resistance of line
      • Voltage & Current Transformer (CT & PT) errors
      • Insufficient accuracy of line parameters due to neglecting of line transposition, distributed capacitance etc.
      • Uncertainty of zero sequence impedance due to variation of earth resistance along the line corridor
      • Load flow
    • TWFL system monitors travelling waves at both ends of transmission lines & provides accurate fault location(fault distance, tower number) for all type of power lines including:
      • AC, HVDC and Series Compensated Transmission Lines
      • Lines with T branches
      • Lines containing cable and overhead line sections
      • Measuring fault distance of single phase to ground fault in non-eff ectively earthed Distribution System
    • Travelling wave measurement technique used gives fault location within one tower span and with best accuracy of ±50 meters irrespective of line length, line parameters, fault resistance, CVT transients, conductor & tower geometry.
    • Such accurate fault location greatly reduces the search time to find out the fault to help quick recovery of the system.

    PD Defect Location in High-Voltage Equipment Insulation by Acoustic Sensors To act on deteriorating insulation the source of PD must be known.The insulation defects produce partial discharges, which emits electrical impulses, radiation of electromagnetic waves as well as acoustic signals.The AR700 measures acoustic signals with multiple sensors spread over the transformer. Then the software determines the failure location using the time difference of all incoming signals. Finally, these coordinates are shown in a 3D model of the transformer. AR700 device is used for measuring of acoustic signals on the external surfaces of gas-insulated breakers and substations, power transformers and other tank high-voltage equipment. The acoustic signals are caused by partial discharges in the insulation, which is the sigh of the defects.The advantage of “AR700” device is the quick installation of the acoustic PD sensors on the external surface of high-voltage equipment tank. The sensors have magnetic holder that is why there is no need to de-energize the equipment for the sensors installation. “AR700” device has 4 syn-chronic channels for acoustic signal measurement. This gives the possibility not only to find the defects in the insulation, but also to locate them. The location function of the “AR700”device is unique for acoustic devices.

     

    Features

    • The signal analyses and the PD zone location could be carried out both in manual and automatic modes.
    • Software calculates the fault location based on the time difference between the incoming signals.And report is generated about PD source location.
