Wide Application Range

  1. Leroy Somer LSA series medium-large brushless diesel/gas generator sets (100–1000kW)
  2. Industrial park multi-unit parallel power stations, ABS certified marine auxiliary gensets, mining prime power units
  3. Old analog R438/R448 AVR aging, voltage hunting, parallel reactive unbalance, no temperature monitoring fault upgrade replacement
  4. Leroy Somer OEM complete genset supporting, global power rental & maintenance shop genuine spare parts stocking
 

Common Equipment Failures Solved

  • · Old analog R448 voltage hunting under harmonic UPS/VFD heavy loads, large voltage dip when load suddenly applied
  • · Multi-generator parallel cannot evenly distribute reactive power, large circulating current leads to AVR overheating trip
  • · No winding temperature monitoring, generator overheating easily damages insulation winding
  • · No fault history record, difficult to judge root cause after generator shutdown
  • · Need PC batch parameter setting for mass OEM genset production, analog AVR only manual knob adjustment low efficiency
