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.
- 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.
