Abstract
resumo medição de resistência elemento em um medidor de energia elétrica um método mede a resistência de um elemento que está operacionalmente acoplada para receber uma tensão de linha ac. o método inclui a obtenção de um valor de medição de tensão a partir de um primeiro v1a primeiro lado do elemento, numa primeira vez, e obtenção de uma segunda medição de tensão a partir de um valor v2a segundo lado do elemento na primeira vez. o método também inclui a obtenção de um primeiro valor de medição de corrente ia através do elemento na primeira vez, e obter um segundo valor de medição de corrente ib através do elemento na segunda vez. o método inclui ainda a obtenção de uma terceira tensão de v1b valor de medição a partir do primeiro lado do elemento a uma segunda vez, e a obtenção de uma medição de tensão quarta valor v2b a partir do segundo lado do elemento na segunda vez. o dispositivo de processamento determina a resistência de, pelo menos, em parte com base nos valores v1a, v2a, v1b, v2b, ia e ib. a determinação baseada em uma diferença ajustada de v2b e v2a.
