    • Ultra Isolation Transformer is manufactured by us with the aid of latest technologies to protect the Isolating sensitive equipment. We also offer power isolation transformers and super isolation transformer in the market. The Ultra Isolation Transformers are specially designed for sensitive critical equipment like computers & peripherals, medical instrumentation, digital communication telemetry systems, CNC Machines etc. and stopping such disturbances generated by the noisy equipment load from being injected into the power line. Multiple shielding techniques employed reduce the inter winding capacitance to below 0.005 Pico farad and increase D.C Isolation to over 1000 Megohms. Technically, transformers that have no direct current path between their primary & secondary windings provide Isolation. Other commonly used, transformers even if they have separate primary & secondary winding are intended to convert the input voltage to a more useful level & do very little to attenuate the passage of noise or transients from primary to secondary. Even through both are separately wound transformers, they are substantially different w.r.t construction, specification & performance characteristics. In shielded transformer, Four Low impedance path exists for noises to pass to secondary & vise versa. : The High Value of Coupling Capacitance. The Maximum Linkage of Magnetic Field. The Leakage Current. Static transformer of Electric Noises.   Provides Protection Against : Line Voltage transients Spikes D.C Leakage

    • Booster transformers are used in electric railway AC catenary feeders to collect the return current from the rails and the earth to the return conductor.   In railways, the electric current is taken from the catenary conductor to the locomotive, where the energy is used by electric motors and fed to the earth-connected rails, which are part of the return circuit. From the rails, however, the return current may deviate around to unintended or harmful places like metallic pipelines, bridges, communication cables, etc. The stray currents bring about interference in communication systems and other electronic devices due to passing trains. Booster transformers are used to eliminate the stray currents and the disturbances, obliging the return current to flow to the return conductor. Product scope: Primary voltage: 15 or 25 kV Current: usually 200 - 800 A Frequencies: 16.67, 25, 50 or 60 Hz Power ratings: 100-800 kVA Hermetically sealed tank

    • High Isolation: It offers superior isolation between the input and output, ensuring that any fluctuations, spikes, or surges in the incoming electrical supply do not affect the connected equipment. Noise Reduction: These transformers are excellent at filtering out electrical noise, preventing electromagnetic interference (EMI) and radio frequency interference (RFI) from entering the system. Enhanced Safety: By isolating the load from the main power supply, ultra isolation transformers provide additional safety, especially in environments where equipment damage or human injury from electrical faults is a concern. Regulated Power: They help maintain consistent voltage levels despite fluctuations in the power grid, which is particularly important for sensitive electronic devices.   Design: These transformers are often built with a shielding layer and advanced winding techniques to ensure the highest levels of isolation and stability.

    • A range of high quality toroidal transformers with twin 115VAC. primary windings and a wide choice of secondary voltages.The primary windings can be connected in series or parallel to cater for 115V or 230V 50/60Hz AC inputs. All leads for both primary and secondary are double-insulated enameled wire with stripped wire ends thereby reducing assembly time.There are no air gaps in the core & no vibrating laminations. The reluctance is low, resulting in very low magnetizing currents with savings in power consumption. A further benefit of this gapless core is the reduced level of radiated electrical noise (hum field). The simple construction of the toroid and the resultant saving in weight as compared to the conventional laminated transformers makes this range particularly attractive for compact power supplies and slimline equipment. Weight of conventional laminated transformer of 1 KVA is approx.12 kg. whereas weight of TOROPOWER toroidal transformer is approx.7 kg.

    • Any Double Wound Transformer is internally an isolation transformer as the primary and secondary are isolated from one another through insulation. However, modern machines and systems need a truly isolated, clean and stable power requirement. This is ensured by an Ultra Isolation Transformer (UIT), it provides for total electrical and electrostatic isolation with most effective screening of spikes, surges and transients, further it gives a true isolated local neutral and dedicated earth which is very essential for modern machines. Ultra isolation Transformer attenuates common mode noise and transverse mode noise and provides for noise or interference free power. In principle, UIT only transfers 50 Hz. Power by transformers action through mutual inductance. It prevents transfer of RF and HF disturbances with extensive insulation between primary and secondary. The insulation levels withstands HV breakdown strength of 2.5 KV and gives a DC Galvanic isolation of above 1000 megohms.

    A distribution transformer is a transformer that provides the final voltage transformation in the electric power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer made AC power distribution feasible; a system using distribution transformers was demonstrated as early as 1882. If mounted on a utility pole, they are called pole-mount transformers. If the distribution lines are located at ground level or underground, distribution transformers are mounted on concrete pads and locked in steel cases, thus known as pad-mount transformers. Distribution transformers normally have ratings up to 200 kVA, although some national standards can describe units up to 5000 kVA as distribution transformers. Since distribution transformers are energized for 24 hours a day (even when they don't carry any load), reducing iron losses has an important role in their design. As they usually don't operate at full load, they are designed to have maximum efficiency at lower loads. To have a better efficiency, voltage regulation in these transformers should be kept to a minimum. Hence they are designed to have small leakage reactance.
