Current and voltage digital transformation in a modern

Conventional and Non Conventional Instrument TransformersMerging UnitConclusionsConventional transformers based on iron cores introduce measurement errors. Due to the wide dynamic range of current signals on power systems, current transformers for protection need large cores to avoid saturation under fault conditions. Due to the nature of the magnetic core material, however, these large cores produce significant errors at nominal current, which renders them impractical for metering purposes. Therefore metering-class transformers need to be introduced resulting in increasing costs. Conventional wired 1A/5A current transformers (CT) circuits have thermal overload constraints, and pose increasing burdens on the core as cross-site wire run lengths increase. Techniques that do not require the iron core of conventional transducers can overcome the limitations. The solutions use different sensor technologies such as optical and Rogowski coils. In practical implementations, the techniques require sophisticated solutions employing digital signal processors and microproc...Get price
