SA 30i+, the wireless Leakage Current Analyser from SCOPE is a State of the Art, On-line test system for Residual Life Assessment of Metal Oxide Surge Arresters. The instrument measures and directly displays the values of Total Leakage Current and Third Harmonic Resistive Leakage Current. It provides system harmonic compensation as per IEC 60099-5-B2. It provides Corrected Resistive Leakage Current after applying correction factors for change in system voltage & temperature.

The SA 30i+ can be pre-loaded with the LA identity details (LA Identification, Type, Serial Number,Location, Rated Voltage etc.) and tests conducted on the same ID of the arresters are saved under the same folder. Trend analysis software, SAData picks up this data and stores them in a similar fashion on a PC. This analysis software enables the user to take a decision to repair/replace the arresters considering safety limits.

SA 30i+ is designed to work under the hostile electrostatic noise found in live EHV switch yards upto 765 kV

Sheath Fault Locator is used for the identification of Sheath/earth faults which can get developed in any type of underground cable like LT or HT power cable or in unshielded multi core control cables. It can be a manufacturing defect or can get developed by improper handling during laying / external damage or any other reason due to which the metallic armour or cores develop leakage with the mass of earth. These faults can remain undetected for a long time as they do not hamper the working of the cable. However, this fault gets converted to a full-fledged fault

over a period of time.

CFL SFL 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.

Features

  • Three manually selectable convince DC ranges for application.
  • Cable and cable sheath testing up to 5 kV between metallic sheath / armour and mass of earth.
  • Automatic sheath fault pre-location with high precision measuring bridge method.
  • Cable sheath fault pin pointing by pool of potential method / fall of potential method /potential difference method.
  • Burn mode for conditioning the sheath fault - Conversion of high-resistance faults in LT cables.
  • Maximum 400 mA current gives better results.
  • Extremely user friendly to calculate the fault distance; uses a micro-controller based fault distance calculator that enables the operator to get the pre-location measurements with precise accuracy.
  • Automatic discharging facility of cable under test, in case of power failure or after switching off.
  • Continues operation for extended period in case of pin-point difficult sheath faults.
  • Rugged construction and easy to carry on site.

Cable Fault Secondary Impulse Filter CFL SIMF is mainly used for high resistance and flashing fault test for power cable with the voltage below 10kV, and for fault location with Secondary Impulse with conjunction of Pre-locator and HV surge generator .Latest fault locating technique for high resistance and flashing faults is Secondary Impulse Method (SIM).This method offers highly reliable results for faults on any type of power cable. It converts the faults to low resistance nature by creating arc across the fault. With the help of filter, the arc is sustained for extended period during which the pre-locator instrument CFL PL3 sends Time Domain Reflectometer (TDR) waves to the fault. These waves reflect back from the fault point and appear on the display as a short fault. This method gives precise result of fault distance for high resistance and flashing nature faults.

SIM filter SIMF is designed for mounting in a van for quick fault location. It can be mounted in a rack mounted system.

It is passive filter having own output power source. It uses the energy of the surge generator to create arc at the fault point.

A high voltage switch incorporated in the output circuit facilitates selection of SIM or ICM mode.

The most versatile Cable Fault Pin Pointer yet, SCOPE’s CFL PP3 is suitable for pin-pointing as well as route tracing of any type of power cable. For pinpointing it is used along-with CFL SG Series Surge Generators from SCOPE and for route tracing it is used along-with Audio Frequency Generator, CFL AG2 from SCOPE. Advanced technology with features like time lapse measurement makes it a tool that can tackle complicated faults easily. 

Ambient noise during pin-pointing has always been a problem. CFL PP3 with simultaneous display of magnetic and acoustic waveforms indicates the exact fault spot eliminating the above problem. It guides the operator about the lay of the cable under test during pin-pointing. The LCD display constantly gives information to the operator about any deviation of the cable route being followed. The instrument offers results based on vision. Thus the ground microphone becomes secondary tool to locate the exact fault spot.

The instrument incorporates separate route tracing circuit to be used with Audio Frequency Generator, CFL AG from SCOPE. The system has flexibility of coupling to the cable galvanically (direct connection) for isolated cable and inductively coupled if the cable is live. The depth of the cable under test is located with conventional triangulation method with precise accuracy. This system configuration can also be used to pin-point low resistance welded faults, where surge generator cannot be used.

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.

CFL PL4 Power Cable Fault Locator is a portable, easy to use cable fault pre-location instrument. It uses the Time Domain Reflection (TDR), Secondary Impulse Method / Multiple Impulse method (MIM) and Impulse Current Method (ICM) on low, medium and high voltage cables.
