Very nice explanation

[@abhistatus.....]

Bahut mast sir ji ab padne ka man kar raha hai

[@patakotisrinivas1918]

Nice explanation sir

[@trueandlaughingtouch5654]

Please explain inrush current with example for 33/11 kv power transformer

[@omprakashtiwari9492]

Nicely explained thanks

[@vivekkumarmaurya1344]

Hi TechInsight good information on inrush current. However to overcome effect you suggested to switch on Trnsfo in 90degree instead at zero radianas ! how to switch on at 90degreecould explain any techniques-thanks

[@techinsight1418]

Working on it....wait for upcoming videos

Hi sir...4mva 11kv/.433kv transformer hai..ht full laod 269 amps aprox...ht vcb panel ct ratio 200/1 amps kya relay starting time trip hoga...inrush current se...relay micom p 122.

[@rafikjamadar8772]

Sir inrush current kitna jayega aur kitne time ke liye..pls reply

[@drg3056]

Impossible to manually Connect / switch on exactly at A point, If you miss it, your correct rated fuse will surely blow. So do you have an perfect time switch ?

[@santhoshdhanajaya815]

Sir When power cut off and suddenly power ON i MCB are tripping (more non inductive load are present)

[@techinsight1418]

Initially there will be transient current, just sufficient to surpass your mcb rating

[@hastimalnahar7515]

Pl. Clear that Inrush current is only flow when transformer is on no load as per your video...

[@techinsight1418]

when we connect or load a transformer

[@wiltonsimbong2237]

Why is the inrush current value negative?

[@omprakashtiwari9492]

Sir in field what precaution should be taken, to charge power transformer

[@techinsight1418]

It is advisable that the residual flux should be zero. I have discussed this topic in doubling effect series....

[@vshal7403]

Pie/2 pr switch krenge kaise,... 0.005 second pr possible kaise

[@ratikantaparida3229]

Brother, can you identify inrush current in power transformer using MATALAB ? Please make a video on it.
