    Current Sensors Suitable for Using in Electricity Meters

  • Original language description

    This article introduces the current sensors that are used in electricity meters. It shows their advantages and disadvantages. This paper is especially focused on DC tolerant current transformers and how they can be influenced by the DC component of measured current. Moreover the effect of a strong magnetic field generated by permanent magnets is analysed. Method to eliminate the disturbance and the stealing of energy is then presented. Next, the article deals with Rogowski coils and how it can replace the current transformers in electricity meters. Finally the problem of manufacturing precise coils, suitable for measuring the current in order of tens mA as it is required by the distributors of electrical energy, is presented.

    Sensory proudu použitelné pro elektroměry

  • Czech description

    Příspěvek prezentuje proudové senzory, které lze použít v elektroměrech, jejich výhody a nevýhody. Především je zaměřen na transformátory odolné vůči stejnosměrnému proudu a ukazuje, jak je lze ovlivnit společným působením silného magnetu a stejnosměrnésložky měřeného proudu. Dále se zabývá vzduchovými cívkami, které mohou být dobrým nástupcem proudových transformátorů a jejich problémy při měření proudů v řádech desítek mA tak jak je požadováno výrobci elektroměrů.
