Transformer me koun koun sa loss hota hai?

-
Transformer me kuch different tarah ke losses hote hain:

1.Copper Losses (I²R Losses): Jab current primary aur secondary coils ke through flow karta hai, tab coil ke copper wires me resistance ke karan heat produce hoti hai. Is heat ko copper losses ya I²R losses kaha jata hai.

2. Iron Losses (Hysteresis Losses aur Eddy Current Losses): Ferromagnetic core ke iron material me magnetic field ke change ke karan hysteresis aur eddy currents utpann hote hain, jo energy ko dissipation me convert karte hain. Isse iron losses utpann hote hain.

3. Stray Losses (Leakage Flux Losses): Transformer me flux leakage hoti hai, matlab ki magnetic flux ka ek hissa core se bahar leak kar jata hai. Isse stray losses ya leakage flux losses kehte hain, jo energy ko loss me convert karte hain.

In losses ko minimize karke transformer efficiency ko improve kiya jata hai.

Short Circuit Test in Transformer

Introduction: Transformer me Short Circuit Test ek tarika hai jo hum transformer ke impedance, copper losses, aur dusre parameters ko determine karne ke liye use karte hain. Is test me, transformer ke high-voltage (HV) winding ko short-circuit kar diya jata hai, aur low-voltage (LV) winding pe voltage ko gradually increase kiya jata hai jab tak rated current flow na ho. Translation: The Short Circuit Test in a transformer is a method used to determine the transformer's impedance, copper losses, and other parameters. During this test, the high-voltage (HV) winding is short-circuited, and the voltage on the low-voltage (LV) winding is gradually increased until the rated current flows. Transformer ka Short Circuit Test: Ek Step-by-Step Guide Step 1: Preparation ● Ensure karen ki transformer de-energized aur safely isolated ho. ● Test aksar low-voltage (LV) side pe kiya jata hai, jabki high-voltage (HV) side short-circuited hoti hai. Step 2: Connections ● LV winding ko ek v...

Magnetism kya hai and It's Application

Magnetism ek physical phenomenon hai jo moving charges ya magnets ke interaction ki wajah se hota hai. 1. Magnetism ki Basic Definition Magnetism ek attractive ya repulsive force hai jo magnets aur magnetic materials (iron, cobalt, nickel) ke beech hoti hai. Magnetic force moving electric charges aur magnetic dipoles ke interaction ki wajah se hoti hai. 2. Magnetic Poles Poles: Har magnet ke do poles hote hain North Pole (N) aur South Pole (S). Rule: Like poles repel (N-N, S-S) aur unlike poles attract (N-S). Magnetic poles kabhi alag nahi hote; agar ek magnet ko tod diya jaye, har part ke paas fir bhi ek North aur South pole hoga. 3. Magnetic Field Magnet ke aas-pass ek invisible area hota hai jisme magnetic force kaam karti hai, ise magnetic field kehte hain. Symbol: Magnetic field ko B se denote kiya jata hai. Unit: Magnetic field ki SI unit Tesla (T) hai. Field Lines: Magnetic field lines North se South pole ki taraf jaati hain aur lines dense hone ka matlab stronger field hai....

Transformer me ferromagnetic material kyu use karte hai?

Transformer mein ferromagnetic materials ka use kyun kiya jata hai? Ferromagnetic materials ka use transformer mein mainly unke high magnetic permeability ki wajah se kiya jata hai. High magnetic permeability ka matlab hai ki ye materials magnetic flux ko apne andar se easily pass hone dete hain. Isse kya fayda hota hai?   Zyada magnetic flux: High permeability ki wajah se, transformer mein zyada magnetic flux hota hai, jisse transformer ki efficiency badhti hai. Less core loss: Isse transformer ke core mein kam heat loss hota hai, jisse transformer ki efficiency aur life badhti hai. Small core size: Zyada magnetic flux ko handle karne ke liye, core ko bada nahi banana padta, jisse transformer ka size aur weight kam ho jata hai. Iske alawa, ferromagnetic materials ki aur bhi kuch properties hoti hain jo unhe transformer ke liye suitable banati hain. High saturation point: Ye materials high magnetic field mein bhi apni magnetic properties ko retain rakhte hain, jisse tra...
