Capacitive Voltage Transformer (CVT)
Definition: A Capacitive Voltage Transformer (CVT) is an electrical device that steps down high-voltage signals to a lower measurable voltage level. CVTs are commonly used
Transformer
Transformer is the static piece of equipment used for step up and step down the voltage for economic transmission and utilization of electrical power.
In this section we are adding all the technical articles related to transformer like step up transformer, step down transformer, ideal transformer, efficiency and losses, regulation, percentage impedance.
We will also discuss about parallel operation of transformers, copper loss and no load losses and its calculation, all types of routine and type tests, converter duty transformer,dry type transformer, k factor of transformer, maintenance of oil filled and dry type transformer, transformer protection equipment like buccoltz relay, PRD and oil and winding temperature measurement etc.
We will also discuss about the open and short circuit test on transformer.
Open Circuit and Short Circuit Test of Transformer
Open and short circuit tests of the transformer are conducted to determine the equivalent circuit, voltage regulation, no-load losses, copper loss, and efficiency. Transformers are
Sweep Frequency Response Analysis Test | SFRA Test
The SFRA test of the transformer determines the physical condition of the transformer windings. Why is it crucial to carry out this test? After manufacturing,
Booster Transformer- Definition & Explanation
A booster transformer is commonly used near the end of a power transmission line to increase the voltage to a desired level. It regulates the
NGR Full Form in Electrical
NGR full form is the Neutral Grounding Resistor, which is used in the electrical system to protect the transformer and generator. As the name suggests,
Polarity Test of Transformer -Explanation and Diagrams
The polarity test of the transformer is performed to determine the direction of induced voltages in the primary winding and the secondary winding. The polarity
Auto Transformer: Definition, Diagram, Working, Advantages & Disadvantages
An auto transformer (or autotransformer) is a special type of electrical transformer with only one winding, used to step up or step down the voltage.
Three Phase Transformer Connections
In three phase transformer connections, a transformer can be connected to either the star or delta. As we know, in a three-phase electrical system, there
Why Core Saturation happens in Transformer and What are its Effects
Core saturation in a transformer happens when the transformer’s magnetic core can not no longer carry the magnetic flux. The transformer core can not carry
What is the Vector Diagram of Transformer?
A vector diagram of transformer represents the phasor relationships between a primary and secondary voltages and currents. It is an important tool for understanding the
