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,
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.
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 voltage. In
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
Transformer on NO Load Condition- Phasor Diagram of Transformer
A transformer on no load means its secondary winding is not connected to the electrical load and the current in the secondary winding is zero.
What is Power Transformer Diagram?
We can know the different components of the transformer and connections by a power transformer diagram. The power transformer diagram shows the interconnections of the
What is Magnetization current in Transformer?
A transformer draws a certain amount of magnetization current from the source when its secondary winding is not connected to the load. This current at
Centre Tapped Transformer- Construction, Working & Applications
A centre tapped transformer has a center tap on its secondary windings. The center tap divides the secondary windings into two equal parts, and it
