Typical Challenges

  • Hunting of Diesel Generator even at partial loading condition
  • Heating of DG alternator
  • Low power factor leading to increased reactive stress


Root Cause Analysis

  • Complex load profile of heavy construction machines such as crane and welding demanding high reactive power which DG sets are not designed to supply
  • Increased reactive stress on DG due to sudden spikes/jerks in reactive power
  • Inflated peak kVA demand due to transitory reactive jerks



  • P2 Power Hybrid Filter at DG incomer (p2p-415-hf3)
  • P2 Power Hybrid Filter at DG incomer (p2p-415-hf4) - in case neutral current is high



  • Reduced reactive stress on generator and therefore reduced peak demand
  • Elimination of DG hunting and alternator heating
  • Reduced fluctuations in peak power demand on the generator
  • Prevention of de-rating of available capacity; generator can be loaded to its maximum capacity
  • Lower capacity generators can be used to support entire load thus resulting in significant savings in capital expenditure on over sized DG sets
  • Reduced current harmonic distortion
  • Same active/hybrid filter installation can be used to improve power factor on grid supply as well
