GENERAL INFROMATION

Demand of power in India is progressively increasing over the years. To meet-up this demand, the Electricity Boards and other Power utilities had to increase their Transmission and Distribution (T & D) network. Though there has been some investments in power generation, but a gap between power are not only incapable of carrying additional power, but also forced to have line losses through lengthy feeders, causing alarming voltage fluctuation at consumer end.

This low/high voltage is applied to all electrical machines like Transformers, Motors etc., hence causing loss in substantial electrical energy, besides damage to the equipments. This compelled is conscious for Conservation of Energy, as Power Tariff is ever increasing.

In addition with this, low/high voltage is also causing "Low Power Factor". Since "Capacitors Bank" installed by the desired level. Therefore, consumers only are penalized to pay compensation, even without utilizing the power.

HT Automatic Voltage Controller is installed on the incoming side of the Transformer and provides stabilized input voltage to the Distribution Transformer. GLOBE'S H.T. Automatic Voltage Controllers are suitable for many varied applications and can be installed either indoor or outdoor.

Globe's H.T. AVC primarily consists of the following

• Step Down Transformer
• Buck / Boost Transforme
• Linear, Plus / minus type vertical Voltage Regulator
• Electronic Control Circuit

Step Down & Buck / Boost Transformer : Inour Step Down & Buck / Boost Transformer we are using CRGO lamination to Transformer are wound with heavy section of electrolytic copper strips / conductor to minimize copper losses for getting better efficiency of the equipment. The Buck / Boost & Step Down Transformers are housed in same sheet steel tank. Radiators are provided for effective cooling.

Linear, Plus / minus type vertical Voltage Regulator: In our regulator we are using heavy section of electrolytic rectangular copper strips to minimize the losses and increase the efficiency of equipment. We are also using self lubricating Carbon Roller assemblies which offers more reliability and trouble free performance of the equipment. Regulator is housed in separate sheet steel tank. The coils of Voltage Regulator are vaccum impregnated and oven dried as IS.

Electronic Control Circuit. : Globe's HT AVC consists of very simple electronic control circuit for monitoring and controlling voltage, repair & maintenance of which is very easy

ADVANTAGES OF INSTALLING HT AUTOMATIC VOLTAGE CONTROLLER

• HT AVC supplies rated Stabilized Voltage to the Transformer, thereby the utilization of the transformer will be up to full rated capacity and is protected from High/Low voltage fluction.
• Where Nos. of Distribution Transformer are installed in a plant, you can put only one HT Automatic Voltage Controller (Regulator).
• Reduction in Breakdown of Electrical Equipments.
• Power Saving (Reduction in Power Bills).
• Unifrom Quality of end products.
• Improvement in power factor and reduction in MDI.
• Better efficiency in plant.
• 80% Depreciation as per Income Tax Act.

TRANSFORMER WITH BUILT IN HT AVC: GLOBE make Transformer with Built in HT Automatic Voltge Controller is a unique product. The equipment is basically a combination of Standard Distribution Transformer and HT Automatic Voltage Regulator. The Fluctuating Voltage from 'Grid' is initially stabilized by HT AVR and then fed to the transformer resulting in the constant LT output within +- 1% Accuracy.

APPLICATIONS

PAYBACK PERIOD

Owing to its high efficiency and associated benefits, the payback period for the cost of Globe's HT Automatic Voltage Controller is from 6-12 months depending upon the input voltage variation and number of working hours of the plant. The HIGHER the input the SHORTER will be the payback period.
