適用范圍：1.1 This standard applies to inductive voltage dividers which are designed to provide a number of accurate ratios of alternating voltage over a range of frequencies and are intended to be used with negligible burden on their output.1.2 In some multi-dial inductive voltage divi-ders, the setting circuit of the last (least signi-ficant ) dial may be resistive.1.3 This standard does not apply to transfor-mer devices intended to supply a burden for measurement purposes which are covered by IS : 3156 (Part 2 )-1978*.1.4 This standard does not apply to any auxi-liary equipment used with inductive voltage dividers.
