Product Description

Power Rectifier and Three Phase Rectifier Transformers

Known for its ‘A’ class insulation standard, this 3 Phase Rectifier Transformer is known for its <35 degree C temperature rising capacity and lower ripple content. This transformer is equipped with electrolytic copper strip to reduce power loss rate. Suitable for overload prone working condition, this rectifier transformer consists of standard grade silicon diodes for uniform distribution of power load. Cold rolled grain oriented sheet made lamination core of this transformer helps to reduce its power loss rate and contributes to its energy efficient nature. RISHAB or AE made DC meters guarantee about its precise operation. The entire structure of this product is epoxy painted to safeguard it against acidic environment. We are a prestigious manufacturer and exporter of standard grade 3 Phase Rectifier Transformer.

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.
