Toroidal Transformers Dealers

A toroidal transformer has ring type core made from cold rolled grain oriented ( CRGO ) Silicon steel strip without any joints and annealed for stress relief after being wound. These wound cores are then suitably insulated by class B insulation and the winding of copper wire is usually done by winding machines.The core being continuous, without any air gap and the path of flux being along the direction of grain orientation, gives an opportunity for optimum use of flux density, besides very low iron loss and exciting current. The primary and secondary windings are closely linked magnetically. Therefore the leakage fluxes and reactance are negligible. A toroidal transformer has its winding spread over the entire periphery of the core. This results in largcr area for dissipating the heat. Till recently all such small low voltage type transformers needs were met almost universally by traditional or conventional El transformers. Now materials are easily available, so it has been possible to develop 'LOW VOLTAGE TOROIDAL TRANSFORMER' giving a whole set of advantages and wide range of applications in place of conventional transformers.

  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.

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.

In fact, because of its low weight & height it is being increasingly preferred over theconventional E&I transformers. In certain applications, its low magnetic stray field & the low mechanical hum are the most advantageous features. The low no load losses of the Torroidal Transformer are of great value in 24 hours stand by equipment. This transformer being custom built proves very economical in large production batches. Dual out-put voltages can be provided if desired. It is also possible to have primary suitable for 115Vor 230V AC, 50Hz.  A Thermal cut off can be incorporated as a special feature at an extra cost. Our manufacturing experience of number of years has given us extensive knowledge & insight in designing the Torrodial Transformer. We use high quality material inputs in order to maintain the quality. The INSULATION between the primary & secondary winding is a fundamental safety feature,and to ensure this we use only,BIS (Bureau of Indian Standards) approved insulating material. Special attention is given to insulation resistance, Hi-pot test & creepage distances.

Lack of interfering hum eliminates the need for magnetic shielding , which is required by conventional transformers, and also enables the toroid to be fitted into electronic circuitry without causing electrical interference. The height of a Toroidal Transformer is considerably lower than the ‘E’ & ‘I’ core transformer. Which means that it’s ideal for ‘Slimline’ electronics. Moreover, the variable core geometry ensures that a Toroidal Transformer can be designed to fit in a specific space – a tremendous advantage where space is a constraint.

The Toroidal Transformers are manufactured by using High Quality Grade CRGO and CRNGO cores as per customers specification. Toroidal Transformers work more efficiently with low Stray Magnetic field.
