RCF: Ratio Correction Factor Multiple current readings by this factor to compensate for transformer losses
AC SERIES PC MOUNT CURRENT TRANSFORMERS
Current transformers (CTs) are used for measurement of electric currents and can be known as instrument transformers. When current in a
circuit is too high to directly apply to measuring instruments, a current transformer produces a reduced current accurately proportional to
the current in the circuit, which can be conveniently connected to measuring and recording instruments. A current transformer also
isolates the measuring instruments from what may be very high voltage in the monitored circuit.
