Power Transformers are suitable for high voltage (greater than 33KV) for power transfer applications. It is used in power generation stations and Transmission substation. It has high insulation level. Power transformers convert power-level voltages, as opposed to electrical signals, from one level or phase configuration to another. They are used to increase or decrease voltage to suit a specific application, and are widely used in electrical power distribution systems
VOLTACTIVE offers you the best quality assured transformer and we have vast experience in manufacturing .We would like to give you the life long service to your transformer.
We manufacture power transformers upto 5MV 33KV/11KV & 33KV/433V

Current-transformer.jpg

The Current Transformer ( C.T. ), is a type of “instrument transformer” that is designed to produce an alternating current in its secondary winding which is proportional to the current being measured in its primary. The basic principle of the current transformer is the same as that of the power transformer. Like the power transformer, the current transformer also contains a primary and a secondary winding. Whenever an alternating current flows through the primary winding, alternating magnetic flux is produced, which then induces alternating current in the secondary winding. In the case of current transformers, the load impedance or “burden” is very small. Therefore the current transformer operates under short circuit conditions. Also the current in the secondary winding does not depend on load impedance but instead depends on the current flowing in the primary winding.

Voltactive offers you the Current Transformers upto 132KV, 33KV, 11KV class with different ratings.

Potential transformer or voltage transformer gets used in electrical power system for stepping down the system voltage to a safe value which can be fed to low ratings meters and relays. Commercially available relays and meters used for protection and metering, are designed for low voltage.In addition to the reduction of voltage and current levels, these transformers isolate the measuring or protective circuit from the main circuit which is operating at high power levels. The current transformers reduce the level of current to the instrument or relay operating range, whereas potential transformers transforms the high voltage to a circuit operating low voltage.

Voltactive offer PT’s upto 132KV, 33KV, 11KV class with different ratings.

Resin-cast.jpg

VOLTACTIVE provides you the complete encapsulation of primary and secondary winding in epoxy resin which prevents penetration of moisture into windings. Contrary to the conventional dry type transformers, the cast coil transformers are better in respect of impulse voltage withstand strength. The cast resin offers very good protection against adverse ambient conditions. These transformers can work without disruption of service at 100% humidity.

These transformers are generally smaller in dimensions and lesser in weights. The construction and installation cost for the sub-station can be reduced by adopting dry type transformers.

Due to encapsulation of coils with cast resin the coils dimensions are stable & no coil tightening is required to maintain the short circuit strength. Also no check of oil level and electrical insulation/oil is required. This leads to saving in cost on account of maintenance.

Voltactive  can manufacture upto 1000KV 11KV/433V with best quality.

lightning-arrester-250x250.jpg

A lightning arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical lightning arrester has a high-voltage terminal and a ground terminal. When a lightning surge travels along the power line to the arrester, the current from the surge is diverted through the arrestor, in most cases to earth. The lightning arrestor protects the structure from damage by intercepting flashes of lightning and transmitting their current to the ground. Since lightning strikes tends to strike the highest object in the vicinity, the rod is placed at the apex of a tall structure. It is connected to the ground by low-resistance cables. In the case of a building, the soil is used as the ground, and on a ship, water is used. A lightning rod provides a cone of protection, which has a ground radius approximately, equal to its height above the ground.
