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.
Measurement Transformers. 3.2.1 The terms "current transformer" and "voltage transformer" used in paragraphs 3.3 and
Measurement Transformers. For each circuit, current transformers ("CT") and voltage transformers ("VT") shall comply with the requirements set out in Sections 5.1.1 and 5.1.2. Additionally, where a combined measurement transformer (VT & CT) is provided the "Tests for Accuracy" as covered in clause 8 of IEC Standard 44-3 covering mutual influence effects shall be met.
Measurement Transformers failure/fault characteristics), on-site accuracy tests shall be performed on such Meters at intervals not exceeding 5 years for Meters for the measurement of Active Energy and intervals not exceeding 10 years for Meters for the measurement of Reactive Energy;
Measurement Transformers. For all installations with new/replaced measurement transformers the Meter Operator shall confirm and record from site tests and inspections:-
