Dual source Measurement & Current Limiting Facility

  • Measures KWh and KVARh from two sources like EB and DG.
  • When on the alternate source Trips the load if current exceeds the desired limit.
  • Reconnects automatically after 60 seconds.
  • Prevents Overloading / Tripping of DG set caused due to excessive drawing of power by consumers.
  • No need of external current limiters.
