Soalan dari teman: Apakah kesan apabila sesuatu S2 pd CT tidak dibumikan.dan bila aku pasangkan pd meter apa yg akan terjadi..tolong komen...
Jawapan dari saya: Jawapan untuk soalan ko tu aku amik dari http://cr4.globalspec.com/thread/34726/current-transformer-earthing:
"Earthing of CT secondary common wire is just essential as is required for Transformer neutral . This shall eliminate the neutral of CTs ( Common ) being floated / circulated
under un balanced conditions / failure of any one CT. Each phase of CTs shall correctly read the current.
This shall eliminate the dangerous over voltages being developed by circulating neutral - & in turn prevent bursting of CTs."
Segalanya kerana circulating current la bro.

earthing pada CT hanye utk bg common saja..so klo xde letak earth pon xpe..tp nnti voltage akan jd floating dan reading xtepat.
Betul tu bro...it's all about circulating current..
For what purpose is this Pembumian di Current Transformers used?
Frank;
kindly reread the post.
Biar betul bro, not install grounding x jadi apa2, dan itu hanya circulating current. Apa itu circulating Current ?, mcmana CC boleh Jadi ?, jangan pakai hantan ja jawab bro, buka buku IEEE apa dia cerita, refer to transformer working pricple...

bro jgn le main nk hentam gak..klo bro tau jwpn sbnr jwp je dan btolkn jwpn kami..xslh pon share ilmu..dan earth pada ct tu utk safety gak if klo blaku open circuit kat secondary.
P/S : ada ilmu share2 jgn nk hentam org..
bahya x...apa effect padacdiri kita??
