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.
The transformer can be categorized into core type and the shell type.In a core type transformer the winding encircles the core whereas in a shell type transformer the core encircles the winding. The winding encircles the core of a transformer. The Single phase transformer has two limbs and three phase transformer has three limbs.
💡 Key learnings: Transformer Oil Defined: Transformer oil (insulating oil) is essential for cooling, insulation, and protecting transformers from oxidation. Types of Transformer Oil: Two
Transformers are always rated in kVA (kilovolt-amperes) rather than kW (kilowatts) because their design is based on voltage and current capacity, not the power factor
🔎 Quick Summary – Key Learnings from the Acidity Test of Transformer Oil Purpose: Measures the amount of potassium hydroxide (KOH) needed to neutralize acids
💡 Key learnings: DGA Definition: Dissolved gas analysis of transformer oil is a method used to examine gases formed due to thermal and electrical stresses
A transformer is an essential electrical device that changes the voltage level of alternating current (AC) without altering its frequency. The working principle of a
The transformer is a vital link between the load and the supply. The efficiency of the transformer is very important in view of energy saving.
Understanding the EMF equation of transformer is essential to grasp how transformers work. When a sinusoidal AC voltage is applied to the primary coil, it
The burden of the current transformer is expressed in VA. The total VA burden should be considered when CT is used for measuring or protection
Transformer Over Fluxing Protection protects the core from overheating caused by over-fluxing. The voltage and frequency ratio (V/f) is responsible for over-fluxing in the transformer.
