ADVANTAGES OF POWER’S MAKE ROLLER TYPE RECTIFIER AS COMPARED TO CONVENTIONAL MAKE RECTIFIER & THYRISTORISED RECTIFIERS

Roller Type Regulator

  • No wave form distortion at any load, Electrical wave from is like a moving wheel. For 50% Rated Voltage the Dia of wheel is reduced accordingly i.e magnitude for a wave is decreased.
  • Power Make Roller Type Rectifiers /Thyristorised Rectifiers

  • Higher power factor of more than 98 is achieved .
  • The system is simple and can be repaired and maintenance even by simple mechanic
  • The cost of spares is very negligible.
  • Copper section for particular current is 3 times than conventional make.
  • Carbon roller rolls on coil and has trouble free life of more than 20 years.
  • Over all losses are less.
Thyristorised Rectifiers

  • Wave form distortion in thyristorised type, It is like cutting the wheel by 50% and then moving the wheel. i.e wave from is cut as shown at full magnitude.
  • Specially Designed Rectifiers

  • The power factor is lower between 0.5 to 0.75.
  • The system is specialized and need specially trained Electronic Engineer to repair and maintain
  • The cost of replacement is very high.
  • Copper section for particular current in conventional make is 1/3.
  • Carbon brushes slide on coil, have less life due to sliding on coil & breaks regularly.
  • Over all losses are more.
