What are the factors to be consider for Specifying Transformer

Generally there are many factors to be consider for Specifying Transformer but the most important factors for specifying transformer is listed below, Kilo volt ampere (kVA) Rating Voltage Ratings, Ratio, and Method of Connection (Delta or Wye) Voltage Taps Typical Impedance Values for Power Transformers Insulation Temperature Ratings Insulation Classes Sound Levels Effects of Transformer…

Capacitor Voltage Transformer CVT

In high and extra high voltage transmission systems, capacitor voltage transformers (CVTs) are used to provide potential outputs to metering instruments and protective relays. In addition, when equipped with carrier accessories, CVTs can be used for power line carrier (PLCC) communication. The details of CVT is given below:- Capacitor stack The capacitor stack is a…

Transformer Working Principle

A transformer is based on a very simple fact about electricity: electromagnetic induction. When an electric current flows through a wire, it generates a magnetic field or magnetic flux all around it.  A magnetic field may be considered as being the medium by which forces are transmitted between magnetized materials. In everyday life, magnetic fields…

Types of Transformer

Types of Transformer Transformers can be categorized in different ways, depending upon their purpose, use, construction etc. The types of transformer are as follows, Step Up Transformer and Step Down Transformer – Generally used for stepping up and down the voltage level of power in transmission and distribution power system network.                                                 2. Three…

Distribution transformer maintenance

Distribution transformer Maintenance Today we are going to discuss about the topic  what is Distribution transformer and what are the distribution transformer maintenance. in general distribution transformers are normally considered to be those transformers which provide the transformation from 11 kV and lower voltages down to the level of the final distribution network. In the US  this was,…

What Do Electrical Transformers Do?

What Do Electrical Transformers Do? You may think that electricity is pretty standard but its voltage and frequency varies between countries and regions in a single country. Essentially, electrical transformers are used to change the voltage of electricity so that it is suitable for different appliances and locations. WHERE ARE TRANSFORMERS USED? You might see…

What is Transformers

Transformers: Transformers do not actually make conversion between mechanical and electrical form, but they transfer electric power from one circuit to another circuit. They can decrease or increase the voltage while transferring the power without changing the frequency, but with the corresponding increase or decrease in the current. Transformers also belong to electrical machines. Step up…
