Note) Dedicated current transformers (CT) are dedicated for low voltage under 440V. They can not be
used for high voltage circuit. In case measuring high voltage circuit, make a 2-step construction
by combination of a commercial CT of secondary side current 5A for high voltage and the
dedicated CT for 5A.
