CVT Capacitive Voltage Transformer is a step-down transformer that changes high voltage into low voltage. Capacitor Voltage Transformers transform transmission class voltages into uniformly low, readily measured values that are utilised for high voltage system metering, protection, and control. Normally, it is impossible to detect the line voltage or current in a high voltage system. …
An induction motor resembles a poly-phase transformer with a shorted secondary circuit. As a result, the initial current drawn by the primary in transformers at normal supply voltage is quite high for a brief period of time. In contrast to DC motors, there is no back emf, which results in a large beginning current. When …
What is Transformer Oil Testing? Transformer oil testing is analogous to blood testing for people. Transformer oil testing is one of the most well-known and effective loss prevention strategies, and it need to be a part of each organization’s maintenance schedule. In addition to serving as an early warning system, it also enables us to …

What is a Transformer? Electrical power is transformed from one circuit to another circuit using a static electrical device called an electrical transformer without affecting the frequency. Transformers have the ability to change the voltage while also altering the current. AC current is used for transmission. The transformer operates on the core concepts of electromagnetic …

What is Buchholz Relay? The transformer is safeguarded against internal faults by the Buchholz relay. It is the relay with gas actuators. Between the conservator and the main tank is where the Buchholz relay is located. Such a relay is utilised in transformers with a rating more than 500KVA. Due to financial factors, it is …

What is Three Phase? A typical technique of alternating-current electric power generation, transmission, and distribution is three-phase electric power. It is a form of polyphase system that is utilised by electrical grids all over the world to transfer power. Large motors and other heavy loads are also powered by it. Because it utilises less conductor …
The power factor can be described as the relation between the working power and reactive power. It is the measure of how properly we consume our electric power. If the power factor is low then it could cause poor voltage regulation, and the KVA rating of the machine would be high it can also decrease …

Introduction Another kind of special transformer, seen often in radio-frequency circuits, is the air core transformer.True to its name, an air core transformer has its windings wrapped around a nonmagnetic form, usually a hollow tube of some material. The degree of coupling (mutual inductance) between windings in such a transformer is many times less than …
Introduction Transformers can vary, from a miniature high-frequency audio transformer to a large power transformer, the operating parameters are still the same. These can be divided into eight groups and are posted on the nameplate of any transformer of significant size: VA rating, cooling, transformer rating, frequency, voltage, phase, connections, and taps. 1.VA Rating Every …
Definition of Transformer A transformer is a static machine used for transforming power from one circuit to another without changing frequency. This is a very basic definition of Power Transformer. Since there is no rotating or moving part so transformer is a static device. Transformer operates on ac supply. Transformer works on the principle of mutual induction. History …
