RECTIFIER EQUIPMENTS
Rectifier Equipments are designed for 3 phase 50 Hz AC input supply and are suitable for operations at any voltage between 380 to 440 Volts, Covering a wide range of voltage fluctuation. It is also recommended that the input to the rectifiers should be connected through a proper protective device, to provide positive protection to the personnel and the system, it can also help in maintenance if a fault occurs.

GLOBE ROLLING CONTACT BUCK / BOOST REGULATOR
In our voltage regulator we are using heavy section of electrolytic rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment, and we are using self lubricating carbon roller assembles instead of ordinary carbon brushes which offers more reliability and trouble free performance of the equipment. |

DOUBLE WOUND TRANSFORMER
This is a conventional design, made from electrolytic copper windings. It is vaccum impregnated and conforms to standard specification of B.S : 171 or IS : 2026 regarding the temperature rise and insulation. The primary is delta connected and Secondary has two star connected windings. |
 |
INTER PHASE TRANSFORMER
Connected two star points of the secondary of the main transformer, the inter phase transformer improves the commutation, thereby increasing the rating of the rectifier.
RECTIFIERS
This is made of sturdy, liberally rated silicon diodes arranged in a six-phase/ three phase bridge circuit. Varying number of diodes are connected in parallel depending on the output rating of the unit. The diodes are mounted on Aluminum heat sink assemblies, with condensers across each diode providing hole storage protection. |
