<![CDATA[What is Difference Between Distribution and Power Transformer?]]>Mon, 15 Dec 2014 12:34:20 GMThttp://servokon.weebly.com/home/what-is-difference-between-distribution-and-power-transformer Transformers play a vital role in continuous functionality of the machines and high production. These protect the machines from sudden break downs caused by power fluctuations and regular power cuts.

A wide variety of transformers and stabilizers available in the market to meet with varied requirements of different industries. Some of the most common among these are industrial voltage stabilizers, power transformers, servo voltage stabilizer and distribution transformer. In this blog, we will have a look at the different between power and distribution transformers.


Distribution transformers are more suitable for machines with lower voltage distribution networks.

As against these, power transformers are designed to meet with higher voltage transmission requirements of step-up and step down applications.

Size of transformers:

As per their load bearing capacity, power transformers are also heavy in size. When compared with distribution power transformers, these are bigger in size and have high insulation level. There voltage supply is greater than 33 KV and that too with 100% efficiency.

As far as distribution power transformers are concerned, manufacturers offer these in small sizes, as these are more suitable for domestic purpose. These are used to supply low voltage (less than 33KV) in industrial purpose, while for domestic purpose it is just 440v-220v. These are easy to install, take less space and have low magnetic losses.

Iron and copper losses:

Power transformers have less load fluctuations, because they are not directly connected to consumers. These are preferred in transmission network and loaded fully at once a day. Iron and copper loss takes place at a specific weight throughout the day.

As the name suggests, distribution transformers are sued in distribution network and have direct connectivity to consumers, which causes high load fluctuations. These are not loaded fully, which results in iron loss only once in 24 hours and cu loss according to load cycle.


Power transformers are used as a step up device, while distribution transformers are as distribution device. The former have higher flux density than the latter one.

Maximum efficiency of distribution transformer is 60 to 70%, while power transformers are designed for maximum efficiency at 100% load.

Are you too irritated with the continuous fluctuation? Does it bother you at every odd hour? Are you aware of the fact that these regular fluctuations are the main cause of the damage caused to your gadgets? When the voltage drops it compels the motor to work harder at a lower competence which affects gadget’s life and also results in loss of property and person or both. Way to ignore these facts and not use prevention rather than causing damage to our gadgets. It is advisable to install a voltage stabilizer for all kinds of electrical equipment's because it helps to set exactly the voltage before it reaches the electrical gadgets thereby lengthening its life. It is the primary need of a household now and every household runs with a basic stabilizer to promote the longevity of its gadgets.  Thereby it is good to play safe with your daily equipment's rather than ignore them and set out for a heartbreaking monetary damage.

Have you ever thought how does this high voltage current gets down to a lower one when transmitted to your household? Do you think that the voltage that is transmitted in your home is the same that is distributed to industries as well? Well, the answer is no! The voltage is initially adjusted according to the wants of the various sectors and then is transmitted to each sector. Like, industries have a different requirement than a household for a restaurant to an airport or a railway station, etc. The answer to this is distribution transformer. Distribution transformers are specifically used for converting and distributing electrical energy with high voltage to lower voltages. Principally, high voltage ranges from 11-22-33 KV while low voltage from 250 to 433 V range. However, the frequency remains same before and after the transformer of the electric current. It’s the general information which is required for you to be an intelligent and well knowledge person.

<![CDATA[Electrical Transformers Basics]]>Wed, 02 Jul 2014 11:58:07 GMThttp://servokon.weebly.com/home/electrical-transformers-basicstransformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers range in size from RF transformers a small cm3 fraction in volume to units interconnecting the grid weighing hundreds of tons. A wide range of transformer designs are used in electronic and electric power applications. Since the invention in 1885 of the first constant potential transformer, transformers have become essential for the AC transmission, distribution, and utilization of electrical energy.

Distribution Transformer

distribution transformer was conceptualized as early as 1882. A distribution transformer is that provides the final voltage transformation in the power distribution system, stepping down the voltage used in the distribution lines to the level used by the customer.

There are 5 types of Distribution Transformers:

  • 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

<![CDATA[Bring Voltage Stabilizers to Deal with Power Fluctuations]]>Tue, 17 Jun 2014 12:23:57 GMThttp://servokon.weebly.com/home/bring-voltage-stabilizers-to-deal-with-power-fluctuationSometimes our refrigerator, A/C and motor driven machines drop in voltage below a certain limit that causes the appliances to draw large currents which leads to overheating and consequent power failure. This is the time when voltage stabilizers are used when the supply is unreliable.  

The purpose of servo stabilizers is also the same which is to receive a fluctuating AC voltage of low or high amplitude and to give a constant voltage. They are also used in various manufacturing units and industries as stabilizers play a key role in easing the effects of power shock.

The voltage variations are a common phenomenon in various kinds of power supply systems. In fact they create havoc in modern and advanced electronic equipment's. The voltage stabilizers take care of this electrical problem and avoid the breakdown by ensuring longer life of the electrical equipment's. This also saves energy during high incoming voltages.

The servo stabilizer manufacturers offer all kinds of equipment's starting from oil cooled servo stabilizers to air-cooled stabilizer including three phase stabilizers to single phase servo stabilizers. Further, to maintain the consistency in the performance of the machines they are constantly upgraded.

The main purpose of industrial servo stabilizer is to save the life of costly appliances, medical equipment's, motor lab equipment's, CNC machines etc. used in various industries by rectifying their voltage fluctuations through the incoming AC voltage and bringing down the voltage at the desired level.

At other times, when the circuit breaks trips and then you run to the basement or to the place where there is the electrical panel. You reset the circuit breaker but it trips again. At this time you need to identify the main cause of the issue which is causes the circuit to trip. Basically the circuit breakers are designed to turn off the power when any of the dangerous situations occurs like short circuit, overload circuit and ground fault. Even this issue of constant electrical trip can be overcome with the help of voltage stabilizers. Know more about digital stabilizers visit the website: 
<![CDATA[Importance of Voltage Stabilizers to Protect Electrical Equipments]]>Thu, 12 Jun 2014 12:21:06 GMThttp://servokon.weebly.com/home/importance-of-voltage-stabilizers-to-protect-electrical-equipmentsPicture
The voltage stabilizers provide unfluctuating amount of current electronic devices when power wavers in a house or a business where the electrical devices are located. The sudden power drops and surges can cause serious damage to computers and other sensitive electronic devices.

The main purpose of voltage stabilizer is to keep the voltage in the circuit relatively close to the desired value. The voltage stabilizers are most common electric components because the power supply produces raw current that can harm the equipments. The voltage regulators have an array of specific functions which depends on a particular application.

The function of voltage stabilizer is to store power and provide power from its reserve to the attached devices that cuts back the power fluctuations. Voltage stabilizer is also known as automatic voltage stabilizer or simply voltage regulator. This has been designed to automatically maintain a constant voltage level and protect the equipments against voltage surges, impulsive noises and over voltages.

The work of a voltage stabilizer is to regulate the fluctuating input power voltage and output power voltage which can be 220V or 230V for single phase and 380V or 400 V for three phases. Some voltage stabilizers are incorporated into the Universal Power Supply (UPS) which has a backup battery system, which allows computers to continue working for some time even during a power failure. A UPS helps the computer to shut down properly in order to avoid data loss.

A distribution transformer is another electrical device which provides final voltage transformation in the electrical power distribution system. It steps down the voltage used in the distribution lines to the level used by the customer. The invention of a practical efficient transformer makes AC power distribution feasible which is a system using distribution transformer that was demonstrated as early as 1882.
