special purpose transformers
isolation transformer
An isolation transformer is a type of transformer used to transfer electrical power
from a source to a device while isolating the powered device from the power source
for safety and performance reasons. It provides electrical isolation between the input
and output circuits, preventing the transfer of DC current and reducing
electromagnetic interference (EMI). Isolation transformers are commonly used in
sensitive electronic equipment, medical devices, and audio systems to ensure safety
and improve signal quality.
furnace transformer
Furnace transformers are specialized transformers designed for industrial
applications, particularly in electric arc furnaces used for steelmaking. These
transformers are built to withstand high temperatures and harsh operating conditions
while supplying the necessary power to melt metals in the furnace. They are typically
high-power transformers with robust construction and insulation to handle the high
currents and voltages required in furnace operations.
station transformer
Station transformers, also known as substation transformers, are key components in
electrical substations that step up or step-down voltage levels for transmission and
distribution purposes. They connect the high-voltage transmission lines to the lowervoltage distribution lines or directly to consumers. Station transformers are typically
large and are installed in substations to efficiently manage the flow of electricity
within the power grid.
auto transformer
An autotransformer is a type of transformer with a single winding that serves both as
the primary and secondary winding. It differs from conventional transformers, which
have separate primary and secondary windings. Autotransformers are used for
voltage regulation, impedance matching, and to provide variable voltage output.
They are more compact and cost-effective than traditional transformers but require
careful design and monitoring due to the direct connection between the input and
output circuits.
OLTC transformers (on load tap Changing Transformers)
The core and coil assembly of a distribution transformer is designed to minimize energy loss and reduce heat generation. The laminated steel core is carefully designed to minimize hysteresis and eddy current losses, while the coils are wound to precise specifications to ensure efficient energy transfer.
