IDMT RELAY EASY EXPLANATION | why we use IDMT relay on feeder | What is IDMT over current relay

IDMT RELAY EASY EXPLANATION | why we use IDMT over current on feeder
IDMT is Inverse Definite Minimum Time
Normal Inverse (t) =TMSX(0.14 /(〖(Ia/Is)〗^0.02-1))
Very Inverse(t) = TMSX(13.5 /(〖(Ia/Is)〗^1-1))
Extremely Inverse(t) =TMSX(80 /(〖(Ia/Is)〗^2-1))
A Long time inverse(t) =TMSX(120 /(〖(Ia/Is)〗^1-1))

Sir pls make a video on how to download disturbance recorder for micom relay from agile studio

[@baranitech1026]

soon i will try to make for you

[@baranitech1026]

welcome

[@jagadeeshtattisetti1887]

Can you explain tripping time how you got 5 sec.... Is it TMS?

[@baranitech1026]

please check it using formula

[@raadmunhim]

pls how change LED COLOR IN RELAY REF615 FOR EX. CHANGE FROM RED COLOR TO GREEN COLOR

[@baranitech1026]

REF615 if you configure on Alarm it is Red and if it is on OKAY then it is green

[@myname1693]

One doubt how did you take TMS valve 0.8
What does the TMS value depend on.

[@baranitech1026]

Time Multiplier Setting which is used in formula in curve

[@BMKinfinity32]

Sir i have a long doubt in idmt.
Vi extremly invese and long tiime inverse for what and where use. It is based on any application like motor, incomer trfo feeder. Why selecting this curve. Wher we use this curves.

[@baranitech1026]

its depends on application of load and upstream settings.

[@myname1693]

Bro I want learn relay testings for career up. Please suggest me any courses available online

[@baranitech1026]

same

[@badshahibrahim8475]

@@baranitech1026 ok thank

[@ramgopalpatra9346]

How you consultancy TMS value

[@baranitech1026]

i have considered TMS value for this example in order to explain

[@jims9916]

how do you define TMS is 0.8

[@baranitech1026]

just for explaining i have taken thank you.

[@sreekantpss6997]

Where to use which type of curve?

[@baranitech1026]

this has to follow up you site condition and upstream side also.

[@Sudharshan9834]

How to you get Ia=0.76

[@baranitech1026]

please tell me video timing i will check thank you.

[@Sudharshan9834]

6:33

[@baranitech1026]

for IDMT tripping will start from 110% so for 0.68 - we get 0.748 so i taken little above 110% as 0.76 value for trip time checking
