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.

We bring forth Control Circuit Transformer with basically electric components fitted on the Circuit boards which are then fitted in the Junction boxes and are used in the monitoring of the current passed on to the Oil pipelines, Tank farms and Oil wells to avoid disruption of the flow of the Oil and Gas. A Control Circuit Transformer is a device designed to provide a reduced control voltage for energizing the coils of electromagnetic devices such as motor starters, contactors, relays, & electronic circuits. These devices make up the majority of the loads supplied by the Control Circuit Transformer. Control Circuit Transformer is also referred to as Industrial Control Transformers, Machine Tool Transformers, and Control Power Transformers, Inrush Volt-Ampere & Sealed Volt-Ampere considerations. The proper size, or the VA rating, of the Control Circuit Transformer is important. It will be a determining factor in the life of the transformer, which ultimately will reflect on the proper operation of control devices that it supplies.  Methods of Selecting The methods of selecting transformer VA ratings addressed in this technical paper are applicable to 50-3000 VA. Control Circuit Transformer. The transformers used in this application fall into the dry type insulation category. Typical primary voltages are 600, 480, 240, and 110. Transformers can also be manufactured with special primary & secondary voltage combinations. There are two VA values to be considered when selecting a transformer. Energizing electromagnetic components creates a large momentary surge current, commonly referred to as inrush VA. This is the first VA value to be considered. The inrush VA will last approximately 5-20 milliseconds and can have a value as high as ten times the transformer's nameplate rating. Thus, the inrush VA will be high in value and short duration. A properly selected control circuit transformer is designed to handle the momentary inrush VA and at the same time maintain a secondary voltage within a set range. The second value to be considered is the sealed VA, the amount of volt-amperes required to maintain the energized state of an electromagnetic device. This VA requirement will be 5 to 10 times less than the inrush VA.Specifications Range : 1mA to 20 A Taps : As per client spec.

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.

ndustrial, Substation & Distribution Tfr. Upto 10 MVA, Upto 33kV, ONAN A poly phase Distribution Transformers design is presented in which transformer output pores are accurately constructed in both voltage magnitude and relative phase angle. The design incorporates both main and auxiliary transformers that are used in unison to produce the accurately constructed phases. The main transformer permits rough phase adjustment to be made with the auxiliary transform permitting phase fine tuning. Such a design is particularly suitable in transformer approaches that require output phases that are of a number not evenly divisible by three.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.Distribution transformers are classified into different categories based on certain factors such as:• Mounting location - pole, pad, underground vault• Type of insulation - liquid-immersed or dry-type• Number of Phases - single-phase or three-phase• Voltage class• Basic impulse insulation level (BIL).Distribution transformers are normally located at a service drop, where wires run from a utility pole or underground power lines to a customer's premises. They are often used for the power supply of facilities outside settlements, such as isolated houses, farmyards or pumping stations at voltages below 30 kV. Another application is the power supply of the overhead wire of railways electrified with AC. In this case single phase distribution transformers are used. The number of customers fed by a single distribution transformer varies depending on the number of customers in an area. Several homes may be fed off a single transformer in urban areas; rural distribution may require one transformer per customer. A large commercial or industrial complex will have multiple distribution transformers. Pad mount transformers are used in urban areas and neighborhoods where the primary distribution lines run underground. Many large buildings have electric service provided at primary distribution voltage. These buildings have customer-owned transformers in the basement for step-down purposes. In a secondary network system as used in urban areas, many distribution transformers may be connected in parallel, each equipped with its own network protector circuit breaker to isolate it from the secondary network in case of a fault.Distribution transformers are also found in the power collector networks of wind farms, where they step up power from each wind turbine to connect to a substation that may be several miles (kilo meters) distant.
