Measurement Transformers. (A) The terms "current transformer" and "voltage transformer" used in paragraphs 3.3 and 3.4 below do not preclude the use of other measuring techniques with a performance equal to that specified for such Measurement Transformers. (B) For each circuit, current transformers (“CT”) and voltage transformers (“VT”) must meet the requirements set out in paragraphs 3.3 and 3.4 below. (C) Where a combined unit measurement transformer (i.e., VT and CT) is used, the Tests for Accuracy described in clause 8 of IEC Standard 44-3 in relation to mutual influence effects must also be met. (D) All Measurement Transformers must be of a wound construction.
