Overhead Line Fault Locator

Additional Details

HT-775 SIGMA-3A is a third generation, one of its kind product based on principle of multiple pulse echo co-relation technology using advanced matrix processors. SIGMA-3A gives total solution to line diagnosis. SIGMA-3A is an auto-calibrated portable system comprising of 6 main units: Fault Locator unit; Adapter unit; Signature Analyzer unit, Simulator unit, Fault Indicator unit, Computing System loaded with Taurus Data Management Software (TADMA). The system being a portable kit can be used on any de-energised line from 11 kv to 33 kv.

Distinct Advantages SIGMA-3A is a line fault analyzer which is useful in accurately identifying: all types of open & short circuit fault and inhomogeneities on the line through line signature analysis

Fault Location: Direct Digital display of distance to fault with the accuracy of ±50m. Useful for all type of Open circuit faults; Phase to phase faults; Phase to earth fault and insulator de-capping

Line Signature Analysis Study (LSA): Reveals all the inhomogeneities prevalent along the Serial comparison of this data enables user to infer deteriorating points along the line which could be the cause of power loss, sporadic tripping and eventual line breakdown. LSA is useful in: Identifying Faults; Line Diagnostic Study Monitoring; Moving from Preventive to Predictive Maintenance; New Line Pre-commissioning Certification

 
Portability & Flexibility: Portable off-line system with inbuilt rechargeable batteries can be used as and when required or at periodic intervals on any de-energised line emanating from a sub-station/faulty section

 

Higher Return on Investment: With its remarkable capability of higher resolution, SIGMA-3A can analyze faults faster, with a higher accuracy and more precisely than any other fault detecting/analyzer systems
