17:55 – iec 61850 training : Why third harmonic is dangerous than any other harmonic & why in ICT transformer LV winding is delta connected ?

18:07 – iec 61850 training “: Auto reclosure.pdf
10abb 10:48 -iec 61850 training : Transformer Diff relay micom p632 making alarm any idea to reset relay. It’s a false alarm
10abb 11:13 – iec 61850 training : Clear the fault log operational log.
10abb 11:17 -iec 61850 training : But still alarm coming. Relay may be faulty
10abb 12:59 – iec 61850 training : If fault cleared try to do force reset under options in record.
10abb 13:16 -iec 61850 training : Third harmonic in all the 3 phases when added doesn’t become zero rather it becomes 3 times the phase value which becomes a very high value. To nullify any of the 3 rd harmonics present in primary transformers have tertiary connected in delta which forms a closed loop for the 3rd harmonic current in the secondary side thus cancelling the 3rd harmonic present in primary side by transformer action.
10abb 15:28 -iec 61850 training : Alarm may be communication alarm
10abb 15:28 -iec 61850 training : Then go to communication setting and disable some functions

In normal condition GR1 relay reading 64SI in micro ampere whereas GR2 relay reading in milli ampere hence generating 100%SEF in normal condition. We have checked all the electrical circuit but not rectified. Need suggestion.

Is this actual fault or inrush current according to disturbance recorder?

14abb 20:54 – iec 61850 training : See the second harmonic content in the inrush current with time and compare with your setting you will get the idea

16abb 21:10 -iec 61850 training :
16abb 21:12 -iec 61850 training : Somebody plz help me to understand this.
When MCB is ON at that time why the current does not flow through indicator as it is connected to live wire
16abb 21:16 – iec 61850 training : MCB -low resistance path compare to Indicator
16abb 21:17 -iec 61850 training : I think this may be the reason
16abb 21:17 -iec 61850 training : R u sure
16abb 21:17 – iec 61850 training : Yes
16abb 21:18 -iec 61850 training : Ok dear thank you
16abb 21:21 -iec 61850 training “: Indicator needs both phase and neutral. But this connection seems like it is used the same phase wire before and after the MCB so it may need to be connected in parallel to the load if you wanted to check the indicator.

16abb 21:59 -iec 61850 training : R u sure by your answer
16abb 21:59 -iec 61850 training : I think this is can be the appropriate answer
16abb 22:06 -iec 61850 training : The indicator will glow only when MCB is off/ tripped
16abb 22:07 -iec 61850 training : I know.. But reason?
16abb 22:08 -iec 61850 training : When MCB is on there is no voltage diff across the poles
16abb 22:09 -iec 61850 training : That means there will not be the current through MCB. Is it so
16abb 22:11 -iec 61850 training : My doubt is that if MCB is On why the current doesn’t flow through indicator and why it doesn’t glow?
17abb 06:40 -iec 61850 training : The contract resistance is very low when MCB is closed
A small amount of current will flow through indicator for sure but this will not be sufficient enough to glow the indicator when MCB is closed
17abb 08:49 -iec 61850 training : Ok dear…. Thanks
17abb 08:56 – iec 61850 training “: MCB is useless here. When MCB is off if load current is huge it will blow up indication and lead to disconnected load. However if load current is less so that it fall in rating of indicaton load will always be ON no matter MCB is on or off.
When MCB is on load current will follow least resistance path and will be shared between MCB and indication according to their resistance. Less current will flow through indication which will be small enough that it will not be able to cause illumination of indicaton.

17abb 10:38 -iec 61850 training : This message was deleted
17abb 10:39 -iec 61850 training : Load current depends on series impedance + load impedance and driving voltage. If load impedance is very low the series impedance will decide the magnitude of current if voltage is constant. Indicator will never blow. The purpose of indicator is to monitor the tripping of MCB while load remains
17abb 10:39 -iec 61850 training : in the circuit
17abb 10:43 -iec 61850 training “: Indicator behaves as connected on same phase if case MCB is closed….and acts as connected across when MCB is on.

Check the what type curve MCB used in your panel inline with your load type…
