Salient Features:
Advantage of Roller Type Regulator as Compared to Thyristor Control:
Roller Type Regulator | Thyristor Control |
No wave form distortion at any load. | Wave form distortion. |
Electrical wave form is like a moving wheel. For 50% Rated Voltage the Dia of wheel is reduced accordingly i.e. magnitude for a wave is decreased. | It is like cutting the wheel by 50% and then moving the wheel i.e. wave form is cut as shown at full magnitude. |
Higher power factor of more than 0.95 is achieved. | The power factor is lower between 0.5 to 0.9 |
The system is simple and can be repaired and maintained even by simple mechanic. | The system is specialized and needs specially trained Electronic Engineer to repair and maintain. |
Over all losses are less. | The cost of replacement is very high. |
- | Over all losses are more. |
