The short circuit test is performed on a transformer to find series branch parameters and rated copper loss. This test is always preferred to perform on the high voltage (HV) side of the transformer. The short circuit test is always done at the rated current on that side of the transformer where the test is … Read more
The open circuit test is performed on a transformer to find no-load (or shunt branch) parameters and core loss (or iron loss). This test is also known as the no-load test. This test is always preferred to perform on the low voltage (LV) side of the transformer. This test is always performed on the rated … Read more
The capacitor and inductor are electrical and electronic components. The technology in these components is advancing day by day. In an electric circuit, two types of elements are there i.e. Active Elements and Passive Elements. Active elements are those that possess the energy from their own and deliver it to the other elements. On the … Read more
Inductors are passive components that are used to store energy in the form of magnetic energy in power electronic circuits. The inductors oppose any change in the current flow that passes through them. When the current in the inductors changes, they either gain the charge or lose it to match with the current flow. The … Read more
A computer network is a group of computers connected with each other in a particular fashion to share data and the usage of peripheral devices amongst themselves. Considering the range of the network, computer networks can be divided into three categories that are – LAN or Local Area Network, MAN or Metropolitan Area Network, and … Read more
Networking is nothing but establishing a connection between devices. A computer network is a group of computers and devices connected with each other that allows them to communicate with each other. Depending on the scope of the network, primarily, computer networks are divided into three categories – Local Area Network (LAN), Metropolitan Area Network (MAN), … Read more
Ferrites are magnetic materials that are considered better than pure metals because of their wide range of properties, such as low cost, high resistivity, easy manufacturing, and superior magnetization. They are widely used in radar, audio & video, memory cores of computers, microwave devices, and satellite communication. Their high electrical resistance and low eddy current … Read more
Biasing or applying bias means applying a steady dc voltage. Usually, when we apply a voltage across components like resistors, inductors, capacitors, etc. we do not need to consider the polarity of the voltage applied. But in the case of semiconductor devices such as a diode, BJT, FET, etc., the polarity of the voltage is … Read more
Current transformer and Potential transformer are the types of instrument transformer. An instrument transformer is a special type of transformer that is used in the measurement of high voltage and high current, not allowing measuring instruments to come in direct contact with high voltage circuits. Potential transformer is also known as voltage transformer. In this … Read more
A power transformer is one of the types of transformer. The basic function of this transformer is to transfer electrical energy from one voltage level to another voltage level without changing the frequency. These transformers are used at specific locations in power systems. In this article, we will see the basic characteristics of a power … Read more
