hi all. i hope my question is not out-of-topic ya.. it is more to electrical..
well, i studied about Current Transformer, which it use almost same theory with Voltage Transformer. (i am referring to bar type Current Transformer)
Primary winding is HV side, which is only 1 winding
Secondary winding is output to metering devices, which i assume it have 300 windings.
the formula is
(AMP)p (TURNS)p = (AMP)s (TURNS)s
i have searched the internet, but most not mentioned about secondary current proportional to primary side only. voltage is produced to drive the current only.
what i confuse here is,
isn't that the output should be voltage? the flux generated by primary winding, will induced voltage at the secondary winding. then the voltage (induced at secondary) will depend on the impedance of the external circuit (metering device), to determine how much current flow from CT to Meter?
yup, i am confuse, but i dont know where is my mistake. hope expert here could point out where is my mis-concept, mistake?
thanks a lot.
