Thermal overload Protection Testing For REM 620 Relay By using omicron relay , Motor Protection relay testing
In this section i have discussed for following topic
1.WHAT IS THERMAL OVERLOAD PROTECTION?
2.SOME OF THE ABBREVIATION RELATED WITH THERMAL OVERLOAD PROTECTION?
3.CAUSE OF THERMAL OVERLOAD IN MOTOR?
4.WHAT IS HOT CURVE AND COLD CURVE?
5.HOW TO FIND HOT/COLD CURVE RATIO?
6.HOW TO TEST THE THERMAL OVERLOAD RELAY?
7.WHAT IS THE SIDE EFFECT OF THERMAL OVERLOAD OVER ON MOTOR?
For thermal calculation excel sheet i have attached in google drive if you want any can download it .

Nice video bro, try uploading videos regarding distance protection relays......

[@mohamadsaad-c4y]

Great work sir
I have question about initial thermal value in normal condition ,how much should be this value and this value will effect on the thermal level I read if the motor in normal running ?
I change relay from rem610 to rem615 and the engineer put this value 0

[@baranitech1026]

Initial value should be the surround temperature of the motor. thank you.

[@mohamadsaad-c4y]

@@baranitech1026
What is the benefit of this value or how will effect in the function ?

[@aktrends231]

Siemens motor relay thermal overload,start inhabit,start supervision video podunga

[@baranitech1026]

surely i will make

[@electricaltech4u45]

Nice bro.

[@shubhampatil6327]

Please let me know how you calculated trip time in excel sheet

[@baranitech1026]

we have to make formula on excel

[@bharatprajapati8578]

Please upload distance protection and directional protection video

[@deltech9947]

hi bro what is stall locked rotor current , and how did you plot stand still perpendicular line , in HCR explanation ?

[@baranitech1026]

during the locked rotor we will get one current by keeping that current has a ref. for HCR

[@tufailalam6438]

I was expecting more by this video. Sir kindly do trip time calculation and please upload a video testing of motor protection p222 with single phase kit.. Thanks

[@ahamedmasood9308]

Please send me the excel sheet for rem620 thermal overload protection and briefly explain motor startup supervision protection sir

Can you team me the name of the software you are using

[@yogeshyogeshwar7878]

What is RTD

[@baranitech1026]

Resistance Temperature Detector used for detect temperature

[@baranitech1026]

please follow up in whatsappa group for excel

[@neelpatel7119]

Hindi me video banaye please sir

[@baranitech1026]

i will try hindi also.
