System Strengthening Projects

1. HVDS:

SSE is the largest player in HVDS projects. HVDS is acronym for High Voltage Distribution System. This system is being implemented exclusively for giving supply to agriculture connections on selected 11KV agriculture feeders. Implementation of HVDS involves conversion of Low Voltage Distribution System to High Voltage Distribution System – HVDS by replacing the existing 415V LT line to 11KV HT line and replacing the higher capacity (100/63KVA) Distribution Transformers (also known as “mother DTR”) with lower capacity (25KVA) Distribution Transformers.

In HVDS system, LT overhead line is completely avoided and instead LT AB cable is used from DTR up to consumer agriculture bore well, thus eliminating LT line faults 100%.

Advantages:

  • Reduction in line losses since HV line is taken almost up to consumer load point and on LV side AB cable is used.
  • Failure of agriculture DTRs are minimized as LT overhead line is avoided and also load  per DTR is restricted. Hence, no failure on account of over load and LT faults.
  • Reduction of unauthorized agriculture connections, as one small capacity (25KVA) DTR is erected for two or three agriculture consumers. The agriculture consumers will have a feeling of ownership of transformer due to limited connections on it.
  • As 11KV line is taken almost to the load point, improvement in voltage profile near agriculture pump sets is observed resulting in good performance of motor.
  • Pilferage of electricity is completely avoided as LT AB cable is used from DTR LV up to consumer bore well.

2. RECONDUCTORING PROJECTS:

SSE has executed Reconductoring-Restrengthening Of Existing Ht And Lt Lines With Allied Works On Turn-Key Basis.
