Hello friends, In this part we have explained how to do wiring from PT terminal box to PT MK box for both the cores protection and metering core. Hope this is useful. Any doubts are welcome in comments below keep watching.
Well explained 👏, thanks for sharing valuable, knowledgeable information about Potential Transformer PT. I have a Question ( play video 07:30 ) about secondary FUSE ampere ratings and class. I hope you will reply. Once again thanks
The PT fuse ratings are gradually increase from end use i.e.relay, energy meter, etc... Towards PT MK box... And PT secondary box.. That are starting from 2 amp to the 16 amp... We hope your doubt is clear now. Thanks for watching 👍
The neutral point of the HV side is shown that it is connected to N, I. e earth. Could you elaborate how this is possible, otherwise it will be shorted as phase to ground fault. 😮
its not... as the winding of pt is comes between HV point and neutral.. so, it will not create line to ground fault. winding act as load... just like EHV reactors
@@Insighttecs Thank you 🙏🙏.... Please let me know should We use open delta in PT for protection circuit or not if yes then for all ratings PT or for any specific Ratings PT???
