Rectifiers

ELECTROPLATING, CLEANING, ETCHING, STRIPPING, BARRELLING, ANODISING, HYDROGENATION AND OTHER ELECTROCHEMICAL PROCESS Roller Type Regulator Thyristorised Control 1.No wave form distortion at any load. 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. 1.Wave form distortion. It is like cutting the wheel by 50 Percent and then moving the wheel i.e. wave form is cut as shown at full magnitude. 2.Higher power factor of more than 0.95 is achieved. 2.The power factor is lower between 0.5 to 0.9 3.The system is simple and can be repaired and maintained even by simple mechanic. 3.The system is specified and needs specially trained Electronic Engineer to repair and maintain. 4. The cost of spares is very negligible. 4. The cost of replacement is very high. 5. Over all losses are less. 5. Over all losses are more WHY THE REGULATOR CONTROL IS SUPERIOR TO THYRISTORISED CONTROL IN RECTIFIER
