Omni Enterprises is a name known for reliability and continuous improvement in the file of rolling contact type Automatic Voltage Controllers, Electroplating and Chemical Process Rectifiers and Special Purpose Transformers. The Systems are designed and supervised by a team of qualified engineers having decades of experience to achieve best possible quality to total customer’s satisfaction.

In spite of best efforts, no state electricity board can ensure constant voltage to the customer because of long and inadequate distribution lines and irregular load pattern on distribution transformers. Generally Voltage is low during day time and high during night hours. Moreover on holidays, peak hours, rainy days and when agricultural and Industrial load is switched off, the voltage rises sharply which is more dangerous.

This higher affects the electrical motors (particularly smaller capacity motors upto 7.5 H.P.) in three ways:
  1. Higher current produces higher losses in electrical motors which causes premature failure of winding.
  2. These Higher losses of electric motors also increase the losses of cables, Switches, transformers and other associated equipment.
  3. For smooth continuous operation of motors, over load relays are usually set 10% higher setting.

Servo automatic voltage controller consist of the following :

LINEAR, PLUS, MINUS TYPE VERTICAL ROLLING CONTACT VOLTAGE REGULATOR

In our regulator we are using heavy section of electrolytic grade rectangular copper strip instead of copper wire to minimize the losses & increase the efficiency of equipment. We are also using self Lubricating Carbon Roller Assemblies instead of ordinary Carbon Brushes which offers more reliability and trouble free performance of the equipment.

DOUBLE WOUND BUCK/BOOST TYPE SERIES TRANSFORMER

In our Buck/Boos transformer we are using CRGO lamination to minimize iron losses and coils of Buck/Boost transformer wound with heavy section of multi strips electrolytic copper to minimize copper losses for getting better efficiency of the equipment.

ELECTRONIC CONTROL CIRCUIT AND METER PANEL

The regulator and Buck/Boost transformer are oil cooled, housed in same or separate sheet steel tanks. Radiators are provided for effective cooling. The coils of voltage regulator & Buck/Boost Transformers are vacuum impregnated and oven dried as per IS.

Feature of Servo automatic voltage controller :

TEMPERATURE RISE

Omni Servo Automatic Voltage Controller are designed tor max.35-40 degree temperature rise at top of oil whereas allowed limited or 50’C

CORE

The core is constricted from low loss, Cold rolled, grain oriented, annealed lamination’s of electrical sheet Sheet conforming to the latest international standards. Special frame is built in-house for clamping the core to reduce the magnetic noise as well making the whole structure rigid and robust.

WINDINGS

Coils are wound with paper covered electrolytic grade copper strip or synthetic enameled copper conductors.Cooling ducts are provided to keep the hot spot temperature as low as possible. Coils are dried in electric ovens. Rigid connection support and coil clamping is provided to ensure high short circuit strength.

INSULATION

Precompressed board PARMALI board JAPANEESE insulation paper of best quality is used.

OIL

Oil is tested for resistivity, dielectric and acidic characteristic conforming to lsS36. Before topping up oil is filtered thoroughly.

TANKS & PAINT

The tanks are made of M.S. steel plated/sheets with adequate bracing & stiffeners. All the external surfaces are given a primary coat of Epoxy primer and finishing coat of Epoxy paint for better life.

METERS& CONTROL SYSTEMS

AE meters and quality products for controls are used.

APPLICATION

Through stabilizer are useful for any kind of application, these are most suitable for 24 hour continuous process plants where breakdowns due to fluctuation results in heavy functional losses.
