Linhas de pares metálicos que transmitem sinais de informação de alta frequência acima de várias dezenas de MHz são frequentemente usadas sem serem torcidas, como cabos planos instalados em edifícios, cabos tipo fita instalados em equipamentos de informática e traços em placas de circuito impresso. No entanto, as características de conversão de linhas de pares metálicos não trançados e não balanceados conectando circuitos não balanceados não foram investigadas em uma ampla faixa de frequências na região de MHz. Primeiro, desenvolvemos um método para estimar fatores efetivos de conversão de potência usando uma conexão em cascata de matrizes F, onde o desequilíbrio na impedância e na admitância de cada par de linhas é distribuído uniformemente ao longo da linha. Como resultado, foram obtidas algumas informações úteis sobre as características de conversão de equilíbrio-desequilíbrio da potência efetiva que podem ser usadas para suprimir fenômenos EMI na fiação, especialmente ao longo de várias décadas de altas frequências. Em seguida, tentamos aplicar as características de conversão de linhas de pares não trançados e desequilibrados obtidas em frequências abaixo de vários MHz a técnicas de busca de circuitos de retorno de condutores instalados em edifícios. Foi esclarecido experimentalmente que a profundidade do plano de terra equivalente pode ser estimada comparando os valores de conversão medidos das linhas de alimentação de TV instaladas no local em teste com valores de referência medidos previamente em uma placa de cobre.

Abstract: Metallic pair lines transmitting high-frequency information signals above several tens MHz are often used without being twisted, as flat floor cable installed in buildings, ribbon-type cables installed in computer equipment, and traces in printed circuit boards. However, the conversion characteristics of untwisted unbalanced metallic pair lines connecting unbalanced circuits have not been investigated over a wide range of frequencies in the MHz region. First, we developed a method to estimate effective power conversion factors using a cascade connection of F matrices, where the unbalance in impedance and admittance of each pair line is distributed uniformly along the line. As a result some useful information was obtained about the balance-unbalance conversion characteristics of the effective power which can be used to suppress EMI phenomena in wiring, especially over several decades of high frequencies. Next, we attempted to apply the conversion characteristics of untwisted unbalanced pair lines obtained at frequencies below several MHz to techniques for searching for the return circuits of conductors installed in buildings. It was clarified experimentaly that the depth of the equivalent ground plane can be estimated by comparing the measured conversion values of TV feeder lines installed at the place being tested with reference values measured in advance on a copper plate .
