Control Transformer
We manufacture and supply a wide range of Control
Transformers, which is fabricated from superior quality of raw materials.
The product is appreciated for its durability, comfort, reliability and
specific features like optimum performance, latest technology and compact
design. These transformers are available in various versions like single
phase, three phase, isolation transformer and auto transformer. Packed with
latest features, our control transformers are of world beating standards.
Single Phase
We are one of the leading providers for the
comprehensive range of Single Phase transformers which are used in motor
control, machine tool control, control panels, alarm systems and
distribution boards. We have an army of highly qualified and experienced
professionals who manufacture these transformers with leading technology and
quality finish.

Insulation to Minimize Heat
- Overload Shutdown Terminals Blocks covered with sheet for
protection/Closed Terminal blocks
OPTIONAL FEATURES:
- Enclosure floor mounted
- Multi-Tap primary voltages / Secondary volatges
- Flexible leads , Fuse Holders , Screw less terminal blocks / Brass
Studs
Three Phase
We are indulged in providing specialized Three Phase
transformers used to change values of three phase voltage and current and
made up of three sets of primary and secondary windings. Our supremely
experienced professionals use only the finest quality materials and follow
all international specifications during making of these quality
transformers. Our three phase transformers are available from 500 VA TO 200
KVA.
There are only 4 possible transformer
combinations:
- Delta to Delta - use: industrial applications
- Delta to Wye/star - use : most common; commercial and industrial
- Wye/star to Delta - use : high voltage transmissions
- Wye /star to star / Wye - use : rare, don't use causes harmonics and
balancing problems
DELTA connection
A delta system is a
good short-distance distribution system. It is used for neighborhood and
small commercial loads close to the supplying substation. Only one voltage
is available between any two wires in a delta system. The delta system can
be illustrated by a simple triangle. A wire from each point of the triangle
would represent a three-phase, three-wire delta system. The voltage would be
the same between any two wires
WYE/Star Connetion
In a wye system
the voltage between any two wires will always give the same amount of
voltage on a three phase system. However, the voltage between any one of the
phase conductors (X1, X2, X3) and the neutral (X0) will be less than the
power conductors. For example, if the voltage between the power conductors
of any two phases of a three wire system is 208v, then the voltage from any
phase conductor to ground will be 120v. This is due to the square root of
three phase power. In a wye system, the voltage between any two power
conductors will always be 1.732 (which is the square root of 3) times the
voltage between the neutral and any one of the power phase conductors. The
phase-to-ground voltage can be found by dividing the phase-to-phase voltage
by 1.732
Auto Transformer
We are one of the leading manufacturers and suppliers
of the wide assortment of Auto Transformers. Fabricated from high grade raw
materials, these are transformers having part of its winding included in
both the input and output circuit. Easy to install our transformers are
manufactured in our state of the art production unit with multiple quality
tests. Some of the attributes of these transformers are reliability,
durability and long service life.
Resin Cast Control Transformer
We are one of the leading providers for the
comprehensive range of Single Phase transformers which are used in motor
control, machine tool control, control panels, alarm systems and
distribution boards. We have an army of highly qualified and experienced
professionals who manufacture these transformers with leading technology and
quality finish.
Isolation Transformer
Being one of the leading names in providing excellent
quality products and services, we are offering Isolation Transformers used
to decouple two circuits. Our transformer allows an AC signal or power to be
taken from one device and fed into another without electrically connecting
the two circuits. Made from latest technology and equipments with the help
of highly qualified professionals, these are extensively used in computers
and laboratory instruments.
Standard Isolation Transformers
Isolation Transformers have primary and secondary windings that are kept
physically separate. Sometimes isolation transformers are called "insulated
transformers". This is because the primary and secondary windings are
insulated from each other.
In an isolation transformer the output winding will be isolated, or
floating from earth ground, unless bonded when it is installed.
Shielded Isolation Transformers
Shielded
isolation transformers have all the features of the standard isolation
transformers plus they also incorporate a full metallic shielding (this
shielding is often copper or aluminum) between the primary and secondary
windings. These shielded isolation transformers are then referred to as
electrostaticly shielded isolation transformers. The electrostatic shield ("Faraday
Shield") is connected to earth ground and performs two functions:
- It filters (attenuates) voltage spikes (voltage transients). These
shielded isolation transformers have an attenuation ratio of 100 to 1.
- It filters common mode noise. This is usually an attenuation of
approximately 30 decibels.
Shielded isolation transformers are preferred over standard
isolation transformers because it provides protection for sensitive and
critical equipment.
When more than one shielded isolation transformer is installed between the
source and the load, this is referred to as "cascading" and vastly
improves power quality.
