APEX D
The APEX-D is a revolutionary innovative system significantly minimize the HVDC transmission line downtime and overall line maintenance time. APEX-D is the third generation, one of its kind product that works on the principle of multiple pulse echo co-relation technique, using advanced matrix processors. A single system offers a cost effective monitoring of all DC overhead de-energized lines providing accurate information on all faults and line signature analysis, which give data of all inhomogeneous points.
The overhead HVDC Power Line Fault Analyzer System is designed & developed to be utilized as a precise fault locating tool for main lines with extended applications of line healthiness study, pre-charging and pre-commissioning checks.
Deployment of the HVDC Power line fault analyzer at each substation ensures optimal uptime of the HVDC power line network. This can be achieved through:
- Enhanced life of the deployed HVDC Power Lines
- Identify any fault during commissioning and trips
- Faster deployment of power during disaster management situationsHVDC
Soon Available on GEM Portal
