RE: Dual rated CT
A "two-core" is referred to as a dual-core CT which is two separate cores contained in one housing.
RE: Dual rated CT
For example, a 5P CT is supposed to meet Class-1 accuracy requirement in the load current range.
The problem arises when the client stipulates Instrument Security Factor (Fs) for metering requirement. Protection class CT will not meet this requirement.
