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.
