The following table summarizes some examples of each type of transformer and where they are used: Type Example Application --- --- --- Shell type Three-phase shell type power transformer Substations Core type Single-phase core type distribution transformer Poles Toroidal Toroidal audio transformer Headphones Step-up Step-up power transformer Power plants Step-down Step-down distribution transformer Homes Isolation Isolation instrument transformer Laboratories Auto-transformer Auto-transformer for voltage regulation Industries ## Design of Transformers Designing a transformer involves several steps that require careful consideration of various factors that affect its performance and reliability. Some of the main steps are: ### Specification The first step is to determine the specifications or requirements of the transformer such as voltage ratio, power rating, frequency, ### Specification The first step is to determine the specifications or requirements of the transformer such as voltage ratio, power rating, frequency, losses, efficiency, regulation, insulation, and short circuit withstand capability. These specifications depend on the application and the load characteristics of the transformer. For example, a power transformer for a substation may have different specifications than a distribution transformer for a pole. The specifications are usually given by the customer or the standards and codes that apply to the transformer. ### Core Calculations The next step is to calculate the core dimensions and parameters such as core area, core diameter, core length, core weight, flux density, and magnetizing current. The core calculations are based on the voltage ratio, power rating, frequency, and flux density of the transformer. The core calculations also depend on the type and shape of the core such as shell type, core type, toroidal type, etc. The core calculations can be done using mathematical formulas or software tools. ### Winding Calculations The next step is to calculate the winding dimensions and parameters such as number of turns, conductor size, conductor length, winding resistance, winding reactance, leakage flux, and winding losses. The winding calculations are based on the voltage ratio, power rating, frequency, current density, and short circuit impedance of the transformer. The winding calculations also depend on the type and arrangement of the windings such as concentric, sandwiched, interleaved, etc. The winding calculations can be done using mathematical formulas or software tools. ### Loss Evaluation The next step is to evaluate the losses in the transformer such as core losses (hysteresis and eddy current losses), winding losses (copper losses), stray load losses (due to leakage flux and harmonics), and no-load losses (due to magnetizing current and dielectric losses). The loss evaluation is based on the core parameters, winding parameters, load current, power factor, and temperature of the transformer. The loss evaluation also depends on the cooling method and efficiency of the transformer. The loss evaluation can be done using mathematical formulas or software tools. ### Temperature Rise Limits The next step is to determine the temperature rise limits of the transformer such as hot-spot temperature rise, top-oil temperature rise, and average-winding temperature rise. The temperature rise limits are based on the losses, cooling method, and insulation class of the transformer. The temperature rise limits also depend on the ambient temperature and loading conditions of the transformer. The temperature rise limits can be done using mathematical formulas or software tools. ### Cooling Method The next step is to select the cooling method for the transformer such as natural air cooling (AN), forced air cooling (AF), natural oil cooling (ON), forced oil cooling (OF), water cooling (WF), etc. The cooling method is based on the power rating, temperature rise limits, and installation location of the transformer. The cooling method also depends on the availability and cost of the cooling medium and equipment. The cooling method can be selected using tables or charts. ### Sound Level The next step is to estimate the sound level or noise level of the transformer such as sound power level (Lw) and sound pressure level (Lp). The sound level is based on the core parameters, winding parameters, load current, and frequency of the transformer. The sound level also depends on the mounting arrangement and environmental factors of the transformer. The sound level can be estimated using mathematical formulas or software tools. ### Tap Changers The final step is to decide whether to use tap changers for the transformer such as de-energized tap changers (DTC) or load tap changers (LTC). Tap changers are devices that allow changing the voltage ratio of the transformer by changing the number of turns in one or both windings. Tap changers are used to regulate the output voltage of the transformer under varying load conditions or system voltages. Tap changers are based on the voltage regulation, load variation, and switching frequency of the transformer. Tap changers also depend on the type and cost of ## Process Control of Manufacturing Technique Manufacturing a transformer involves several stages that require careful control of the process parameters and quality standards. Some of the main stages are: ### Core Cutting The first stage is to cut the core material into thin sheets of specific dimensions and shapes using a core cutting machine. The core material is usually grain-oriented silicon steel, which has high magnetic permeability and low core losses. The core cutting machine can automatically stack the sheets into legs and yokes according to the core type and shape. The core cutting machine can also perform butt-lap or step-lap stacking, which improves the flux distribution and reduces the excitation current and core loss. ### Coil Winding The next stage is to wind the conductors into coils using a coil winding machine. The conductors are usually copper or aluminum wires or strips, which have high electrical conductivity and low winding losses. The coil winding machine can automatically wind the conductors according to the number of turns, conductor size, winding arrangement, and insulation requirements. The coil winding machine can also perform concentric, sandwiched, interleaved, or other winding methods, which affect the leakage flux and winding reactance. ### Insulation The next stage is to insulate the core and the coils using various materials such as paper, varnish, resin, oil, etc. The insulation materials provide electrical isolation, mechanical support, thermal dissipation, and environmental protection for the transformer components. The insulation materials must have high dielectric strength, low dielectric loss, high thermal conductivity, low thermal expansion, and high resistance to moisture, oil, fire, etc. ### Assembly The next stage is to assemble the core and the coils into a core-coil assembly using various methods such as clamping, brazing, welding, etc. The assembly methods provide mechanical strength, electrical connection, and thermal contact for the transformer components. The assembly methods must ensure proper alignment, clearance, and tightness of the core-coil assembly. ### Testing The next stage is to test the core-coil assembly using various instruments and methods such as voltage source, current meter, resistance meter, impedance meter, loss meter, temperature meter, sound meter, etc. The testing methods verify the electrical, mechanical, thermal, and acoustic performance of the transformer components. The testing methods must comply with the specifications, standards, and codes that apply to the transformer. ### Painting The final stage is to paint the core-coil assembly using various materials such as primer, paint, coating, etc. The painting materials provide aesthetic appearance, corrosion resistance, and environmental protection for the transformer components. The painting materials must have high adhesion, durability, and compatibility with the insulation materials. ## Installation, Erection, Commissioning and Maintenance of Distribution Transformers Installing, erecting, commissioning and maintaining a distribution transformer involves several steps that require careful planning and execution. Some of the main steps are: ### Site Selection The first step is to select a suitable site for the distribution transformer such as a pole, a pad, a vault, a substation, etc. The site selection depends on the power rating, voltage level, cooling method, and accessibility of the distribution transformer. The site selection also considers the load characteristics, load location, load growth, and system reliability of the distribution network. ### Foundation Laying The next step is to lay a foundation for the distribution transformer such as a concrete base, a steel structure, a wooden platform, etc. The foundation laying depends on the weight, size, and shape of the distribution transformer. The foundation laying also ensures the stability, leveling, and grounding of the distribution transformer. ### Transportation The next step is to transport the distribution transformer from the manufacturing plant to the installation site using various modes such as road, rail, water, air, etc. The transportation depends on the distance, cost, and availability of the transportation modes. The transportation also follows the safety precautions and best practices such as securing, covering, lifting, and handling of the distribution transformer. ### Connection The next step is to connect the distribution transformer to the power supply and the load using various devices such as cables, bushings, fuses, switches, etc. The connection depends on the voltage ratio, ## Advantages of Reading Design of Transformers by Indrajit Dasgupta Reading Design of Transformers by Indrajit Dasgupta has many advantages for anyone who is interested in learning more about transformer engineering.
