About Toroidal Transformers :Toroidal Transformers are passive electronic components, typically consisting of a circular ring-shaped magnetic core of high magnetic permeability material such as iron powder or ferrite, around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications in AC electronic circuits, such as high-frequency coils and transformers. An inductor with a closed-loop core can have a higher magnetic field and thus higher inductance and Q factor than similarly constructed coils with a straight core (solenoid coils). This is because the entire path of the magnetic field lines is within the high permeability core, while in an inductor with a straight core the magnetic field lines emerging from one end of the core have a long air path to enter the other end. In recent years, the use of toroidal (donut) shape cores has increased greatly. The advantage of the toroidal shape is that due to its symmetry the amount of magnetic flux that escapes outside the core (leakage flux) is minimum, therefore it radiates less electromagnetic interference (EMI) to nearby circuits or equipment. EMI is of increasing importance in modern low power, high frequency electronics. A side effect in torus-shaped inductors is that, because the winding surrounds the central hole and the current traverses the winding in a circular direction, there is a weakpoloidal magnetic flux that threads the "donut hole" in the center of the torus, in addition to the main toroidal flux direction parallel to the core of the torus.

  Rogowski Technology of Current measurement With its over 20 years of experience in Toroidal Technology Salzer- Engineers have pioneered the design, development and manufacturing of Rogowski coils and we have been supplying the Rogowski Coils to various OEM’s worldwide.   A Rogowski coil, named after the German Physisct Walter Rogowski, is an electrical device for measuring alternating current (AC) or high-speed current pulses.    It consists of a evenly wound helical coil of wire with the lead from one end returning through the centre of the coil to the other end, so that both terminals are at the same end of the coil. The winding is done on a non-magnetic/non-metal former of constant cross sectional area. The whole assembly is then wrapped around the straight conductor whose current is to be measured. The speciality is there is no metal (iron) core.   01 Rogowski coils have been used for the detection and measurement of electric currents for decades. The voltage output is proportional to the rate of change of current. This voltage is integrated, thus producing an output proportional to the current. 02 Even though Rogowski Coils are low power sensors, the protection system is immune to external electromagnetic fields. 03 Rogowski Coil can replace CTs for protection, metering, and control purposes. 04 Rogowski Coils are accurate, small, light, and easy to install. They do not saturate. 05 Rogowski Coils provide superior differential protection for power transformers, substation bus bars, generators, and large motors. 06 Rogowski Coils do not create hazards for personnel with open secondary, as Conventional current transformers.

Current transformers are used for electrical measuring instruments and / or electrical protective devices. They are very useful in high power circuits where the current is large. Current transformers are subdivided into two main categories. MEASURING CURRENT TRANSFORMERS These transformers are used in measuring and indicating current, that is to reduce the line current to a value which is suitable for standard measuring instruments, relays etc.     PROTECTIVE CURRENT TRANSFORMERS These transformers are used for over current and undercurrent relaying for power circuit protection   TYPE : Current Transformers are normally categorized as Ring / Bar type and Wound Primary Ring / Bar type current transformer : A current transformer where primary winding is provided by 'the user. Wound primary current transformer : A current transformer having a primary winding of more than one full turn wound on core. Current Transformers are wound on Toroidal cores which virtually eliminates error due to leakage flux. Adjusting the number of secondary turns may compensate for some errors.

The company stands tall among the Manufacturers & Suppliers of Toroidal Transformers. The Toroidal Transformers offer many advantages over a conventional laminated transformer. Toroidal Transformer has a round shape with no air gaps and with the primary and secondary windings uniformly distributed around the core, they "lock in" the magnetic field and hence, they are very quiet and efficient. Toroidal Transformers meet today̢۪s requirements for smaller, more efficient, quieter and safer products and they are being accepted in an increasing range of electronic and electrical equipment. With Toroidal Transformers having smaller dimensions, lighter weight and low stray magnetic fields, you can build more compact, lower cost quality products without sacrificing performance. Basics of Toroidal Transformers Toroidal Transformers are built around a ring-shaped core, which, depending on operating frequency, is made from a long strip of silicon steel or permalloy wound into a coil, powdered iron, or ferrite core. A strip construction ensures that the grain boundaries are optimally aligned, improving the transformer's efficiency by reducing the core's reluctance. The closed ring shape eliminates air gaps inherent in the construction of an E-I core.The cross-section of the ring is usually square or rectangular, but more expensive cores with circular cross-sections are also available.The primary and secondary coils are often wound concentrically to cover the entire surface of the core.This minimizes the length of wire needed, and also provides screening to minimize the core's magnetic field from generating electromagnetic interference.

We are considered as one of the leading Manufacturers, Suppliers, and Exporters of Toroidal Core Transformer. Our Toroidal Transformer Core is fabricated under the guidance of experts to ensure its premium quality and dimensional accuracy. We conduct a special process with high degree of precision to manufacture Toroidal Transformer Core to meet the diverse needs of Reactors, Chokes and so on. Manufacturing process The manufacturing of strips wound cores is a specialized process, which requires a high degree of precision. These cores are manufactured from selected coils of crgo electrical steel to yield closely controlled electro-magnetic characteristics and dimensional accuracy. Cores are wound after slitting is done as per the required shape, on the core winding machine. The winding machine automatically stops when the pre-decided dimension is reached. The start and finish ends are firmly spot welded. After winding, the cores are stress-relief annealed to restore the magnetic properties. The cores are bonded where necessary, to provide increased firmness. All cores are spray painted or varnished (as required by customers) and are tested for magnetic properties. Testing Strip wound cores, unlike strip lamination, constitute a complete product and every core must meet the specified performance requirement. Consequently, quality control in the manufacturing of wound cores is vitally important at every stage of process. Dimensional tolerances The coils of crgo steel from which the cores are manufactured are carefully selected on the basis of tests carried in our laboratories to ensure that the correct grade of steel is used. Strict checks are made at every stage from winding to the final stage of spray painting & varnishing to ensure that the finished product is of a high quality. Moreover, each core is subject to inspection and electrical tests at BSP to make certain that our customers are provided with the specified performance requirement. Apart from being fully equipped to meet the exacting standards of testing required, BSP possesses the technical knowhow, the research facilities and the necessary raw-materials.
