Thank you very much for good explanation.

[@owinookello9358]

i 💕 your teachings sir great

[@ismailajarju8222]

thanks

[@vinzers1311]

Very Informative and detail video. ACB's are usually recommended on 800A - 6300A.

[@rameshtripathy5978]

Nice description & definitely helpful to commissioning engineers & maintenance technicians !

[@africantales124]

Nice video. Very explicit.
Please talk on shunt trip and under voltage release coil.

Hi sir super teaching thank you 👍

[@electricalmastar]

Thank you

[@KKumar-sk2kd]

Good explaining thank you sir

[@sohailjanjua123]

Hi, I like your video. Thanks

[@prakashksp2918]

Good explain sir

Ii and Isd can be kept switched on simultaneously?

[@pavankumar-ey3bw]

Good sir

[@abomohamedalrubee5287]

Hi there, thank you for video. the tg began from A to J what this mean?

[@pavankumar-ey3bw]

Hai give me some information. Dip switchs is 1 2 3 4 but setting value is 3 numbers available. In Abb ACB breaker relay setting

👌

[@Sourav8692]

Why I2t on and I2t off term has come for alarm ??

[@thklran6400]

Hi sir, please help, i have trouble at my site, we install transformer 20kv/0,69kv LV side going to ACB siemens 3wl 2000A, load 1 motor 250kw, with DOL starter, the problem indication ground fault in ACB ON status (alarm) during motor start, after 3 second motor run, alarm ground fault is missing, if the setting Ground fault adjust min to max , acb will be trip , ground fault adjust to off, motor normal running, indication ground ON only < 2 seconds

[@benignojeciel7252]

Hi Pare, can u help me, sace tmax7 is tripping without load how can i fix it and set it to rated current 1200amps, nominal current is 1600 amps. Thanks Pare for helping me.

[@electricalmastar]

Hi pare, thanks for your comments and could you tell me when it was Tripp what are the relay been activated

[@arvindchauhan-mi2rh]

From which point it will give to external breaker command for tripping.

[@mohammadafroz4611]

Sir,
In Abb relays for HT panel how to know what current is dangerous when earth fault occurs while charging the transformer...as the settings 0.3 In where In is 100. But when earth fault occurs how to know what current is dangerous and what is not so that we can charge again.

[@siddeshaj552]

Please upload working principle of oltc

[@basavarajus9383]

What is instantaneous current fault in ACB

[@electricalmastar]

Instantaneous fault means phase to phase fault will occur it produce large current that time ACB will trip immediately without time delay

[@bejoyfrancis5598]

Hi IG values of the breaker differs based on rating. Which was not explained

[@prakashksp2918]

How to select the relay settings
L.over load
Flc*0.80 or 0.85
S. Short circuit
Flc* 2times or 3times
Instantaneous current
Flc*4 times or 6 times
G ground
Flc*0.10 or 0.15
Sir but
Short circuit current
2 time or 3 times sent pandra thu epdi sir enna formula
Instantaneous current
4 times or 6 times set in what formula

[@akhildogra7017]

Sir.
My breaker capacity is 800amps all breaker setting is ok but still my breaker tripped at 300amps of load

[@vamshiganapavarapu7885]

Earth fault
A to J means
