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 current 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 & other associated equipments.
3. For smooth continuous operation of motors, over load relays are usually set at 20% higher setting.

With the installation of the Servo Controlled Voltage Stabilizer and maintaining 390/400 volts, the motor will operate smoothly drawing 15 - 20% lesser current

Even after the installation of standard off circuit distribution transformer, the voltage fluctuation on the LT side persists due to limited range of voltage correction of the transformer. To control the voltage fluctuations, it is ideal to install Servo Controlled Automatic Voltage Controller either on LT side or HT side.


MUSKAAN’S make Transformers with built-in rolling contact type AVR suitable for indoor/outdoor installation, copper wound HT Two-in-one system is a revolutionary landmark in the industry when it comes to voltage regulation and stabilization. Even after the installation of standard distribution transformer the problem of low/high voltage on the LT side persists, resulting in improper operation of the electrical equipments, premature failure & production loss of a plant. The standard off - circuit tapping of transformers can correct limited voltage variation and cannot regulate the voltage while in ‘On Load’ conditions. We have developed state of the art technology two-in-one system with Transformers having built-in HT Automatic voltage regulator that operates on load, sleeplessly & gives stabilized voltage on the LT Side. The equipment is basically a combination of HT AVR with a standard distribution transformer.

The Fluctuating voltage from grid is initially controlled by the HT AVR and then fed to the transformer resulting in the constant L.T. Output within +/- 1% accuracy and the biggest advantage being its robust design ; Lesser losses & more efficiency make the distribution transformer to utilize up to 100% capacity.
 

Multiple Shielding Techniques employed to reduce the inter winding capacitance to below 0.005 picofarad and increases DC Isolation to over 1000 Megaohms.

Technically any transformer that has no direct current path between its primary & secondary windings provides isolation from any kind of leakage in Current, Spikes/Surges produced in the system. Provision of electrostatic shield in between primary & secondary winding depends upon its construction, specification & performance characteristics.

Isolation / Ultra Isolation Transformer are being used to protect Electronic & Sophisticated equipments, CNC Machines from the excessive line voltage transients, spikes / surges produced in the system. Electrostatic shielding helps in grounding these spikes & not allowing to pass on to the secondary side of the transformer.

Furnace Transformer are built in delta / star connection with neutral as floating & electrostatic shielding is used to protect the furnace from any kind of Earth Fault Tripping.

These kind of transformers are used for testing applications where variable output is required from 0 to any voltage. These kind of transformers are widely used in transformer / motor / generator manufacturing units to perform various electrical tests.


The construction of these variable transformers is very simple & consists of Buck/Boost Double Wound Transformer and +/- Type linear rolling contact regulator for stepless control. Variable transformers are widely available upto 10 MVA
