Differential Relay Testing (Micom P643)

[@Technicalguy_123]

Sir i have doubt that we need to inject HV LV value after multiplying with matching factor?
Or without matching factor as relay will multiply with matching factor internally?

Go through the playlist for differential relay. I think you will have clear Idea about above

Very nice 👌

[@surendrakverma555]

Very good. Thanks 🙏🙏🙏🙏🙏

When Id is set to 0.3 In, what is In here? since transformer has 2 In. first In for LV side, second is In for HV side

[@rjshtk]

For HV side, In will be the full load current of HV side expressed in secondary terms. Similarly, for LV side, In will be the full load current of LV side expressed in secondary terms.

Hello sir, I designed a differential relay , I want to discuss with you .how can I contact with you

[@ravindrayogi3196]

Why we take is1.002 and is2 3pu and k1 is 30 % and k2 50% .how it comes

[@relayprotectionelectrical]

Is1 is set as minimum as possible in order to give sensitivity to differential relay but it is so chosen that due to mismatch of tap position it should not operate. Again next slopes are given to maintain stability due to through fault. You can go through video ua-cam.com/video/9sc9WsiqmA4/v-deo.html

How did u get end section 1 value as. 67?

[@ranjansahu2362]

Well done sir

[@anilshemade6048]

Plz explain Is1 and Is2.

[@sreehari2969]

how did you get 0.67 in chara. can you explain

Distance protection relay testing and configuration pls sir

[@relayprotectionelectrical]

Thank you for your comment. I will definitely upload video on Distance Relay testing and configuration.
