Distribution Transformer & Single Phase Transformer

 We have talked about transformers in previous articles. In this article, we are going to talk about current transformer, distribution transformer and single phase transformer. Stay with us.

Distribution transformer

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.

Normally, a distribution transformer level is less than 200MVA, while some national norms can allow for ratings up to 5000 MVA to be known as distribution transformers. If the level is more than 200MVA (or 5000MVA in some regions), it’s introduced as a power transformer.

current transformer

A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary.
Based on this form of configuration, the current transformer is always introduced as a “series transformer” as the primary section, which never has more than a very few turns, is in series form with the current-carrying conductor providing a load. read more in this link


Single Phase Transformer

A single-phase load may be powered from a three-phase distribution transformer in two ways: by connection between one phase and neutral or by connection between two phases. These two give different voltages from a given supply. For example, on a 120/208 three-phase system, which is common in North America, the phase-to-neutral voltage is 120 volts and the phase-to-phase voltage is 208 volts. This allows single-phase lighting to be connected phase-to-neutral and three-phase motors to be connected to all three phases. This eliminates the need of a separate single phase transformer.A transformer is an instrument that transforms magnetic power into an electrical type. It has two electrical sections introduced as the primary and secondary windings. The primary section of the device receives power, whereas the secondary winding delivers energy. A magnetic iron circuit introduced as the “core” is typically used to wrap around these sections. more information

Introduction of electric motors and types

Image
  You've probably heard of electric motors by now. A critical piece in all electrical appliances. In this article, we will introduce electric motors in detail and examine its types, so stay tuned. An electric motor is a component that converts electrical energy into kinetic energy. Most electric motors are  electromagnetic -based. Most electric motors are rotary, but there are also linear motors. In a rotating motor, the moving part (usually inside the engine) is called the impeller or rotor, and the fixed position is called the station or stator. The motor consists of electric magnets wound on a frame. Although this frame is often referred to as armature, the term is often misused. Types of Electric Motor Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-...

Introduction and review of Suspension Insulators and Strain Insulators

Image
  In this article, we will have a detailed explanation and review of Suspension Insulators and Strain Insulators. Join us and read this article. First, we will introduce Suspension Insulators, and after reviewing it, we will submit Strain Insulators What is Suspension Insulators  ? The suspension type insulator consists of several insulation parts connected in series and forms a string. In suspension insulators, each porcelain discs is designed to work at 11 kV, and as the operating voltage increases, the number of discs in the string and in series increases as well. For example, the number of insulator discs required is 12 in 132 KV transmission lines.  Read More in Linquip What is Strain Insulators  ? According to  Wikipedia , A strain insulator is an electrical insulator designed to work in mechanical voltage (strain) to withstand the pull of a suspended electrical wire or cable. They are used in overhead electrical wiring to support radio...

Everything you should know about HVAC

Image
What is HVAC? What do you know about it? What is its use? In this article, we will take a closer look at HVAC, so join us to get the answers to these questions and any other questions about HVAC. The importance of HVAC Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of  mechanical engineering , based on the principles of thermodynamics, fluid mechanics and heat transfer. As was mentioned earlier, an  HVAC system  is intended for thermal control of areas as well as comfort for occupants. Temperature is factor that affects the performance and health status of many systems. Take the case of a server room temperature as an example for which high temperature adversely affects the system’s reliability and operation of the servers is a great source of heat ge...
