Isolation Transformers Dealers in Mumbai

All the types of electrical noises, predominantly common mode noises can be eliminated by Ultra Isolation Transformers. Since it isolates primary and secondary or separates neutral to ground bond on the secondary side, can be used to create separately derived source to combat current loops. The Ultra Isolation Transformers are available in different levels of noise attenuation capabilities. The most commonly used are 100 & 120 dB. The coupling capacitance between primary and secondary is direct 1:1 relationship with dB levels. Some of the graphs herewith indicate different types of electrical noises observed in typical Engineering Industries & successfully eliminated.

An instrument transformer’s role is to provide accurate inputs to protection, control and metering systems including revenue metering. To transform currents or voltages from a usually high value to a value easy to handle for relays and instruments. To insulate the metering circuit from the primary high voltage system. To provide possibilities of standardizing the instruments and relays to a few rated currents and voltages.

Ultra Isolation Transformers are needed whenever a clean Power is needed. The instruments that are sensitive to Electrical Noise like Heart Beat Monitor, Ultra Sound Instruments, Giga Counters, UHF Transmitters and Receivers; Ultra Isolation Transformer is an excellent solution. This transformer is built with great care and caution. The Primary and Secondary are split and Inter-Winding Capacitance is considerably reduced by incorporating a Special Shielding Method. The Magnetic Currents are also controlled using the Stamping Grounding Method. The Isolation can be achieved to a degree of 120db and Inter-Winding capacitance of 0•005pf can be achieved.Capacities Available from 1.0 KVA to 100 KVA. SALIENT FEATURES :   Isolates the equipment from noisy powerline Reduces powerline Noise, Surges, Spikes & Transients.

We are one of the well-established Manufacturers and Suppliers of Isolation Transformers in Mumbai, Maharashtra. We use advanced software and machinery for the manufacturing of Isolation Transformers. Buyers from all over the country can place bulk orders for our Isolation Transformers. We have advanced facility for production and efficient logistics for the dispatch of Isolation Transformers across the country.

Engineers, Scientists, Technicians working in laboratories on sensitive equipment have a need for Isolated mains supply, with a variable output Voltage. This facilitates them in testing various devices demanding different voltages & currents. It is also an Electrical Engineering practice to test devices by applying steadily increasing voltage from 0 V to the device rated voltage. To achieve the above objective, it is normal practice to use a Variable Autotransformer (colloquially known as Variac), followed by a 1: 1 Isolation transformer or vice versa. This combination becomes very bulky & heavy with two separate transformers or even with a combined box. It also occupies much of test bench space. This is more so with increasing current rating or VA. It also loses mobility. Radio Electric Pvt. Ltd. has solved this problem by designing Radiotone Double Wound Isolated Variable Autotransformer (colloquially known as Variac). This elegant & compact arrangement uses only ONE transformer on a single toroidal core. The Radiotone Double Wound Isolated Variable Autotransformer provides 2.5 KV Isolation between primary & secondary, primary & body with a Variable Output Voltage from 0V to the required voltage. Various models of Radiotone Double Wound Isolated Variable Autotransformer (colloquially known as Variac) are as Illustrated in the table. This concept can also be used very effectively in DC power supplies with Variable output (eg. Input 230V / 110 V, Output 0 to 25 V, 5A or 0 to 15V, 8A., etc). We also manufacture table-top models of Radiotone Double Wound Isolated Variable Autotransformer with various types of input/output sockets (Shuko / Dual type / Round type, etc) as required.

A distribution transformer or service 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 less than 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.

Symmetrical characteristics allow noise attenuation from sides. No need for extra filter circuits. Can be used where different ground potential exists or the ground of the equipment cannot be earthed. No impedance matching required.
