Abstract: The paper brings to the readers the causes or factors and the extents in which they influence radiation emitted by BPLC network. The typical network topology is used to simulate those causes or factors and the paper tries to come up with theoretical agreement to what was postulated in previous studies. Some of the potential factors are analyzed and their results are discussed for the purpose of verifying the effect and, later, proposing suitable mitigation methods for each identified factor. In this paper the contributions of common mode (CM) current, line bend and the frequency to BPLC radiation are discussed. CST cable studio tools for EMC analysis are applied to simulate and confirm the influence of each factor. The results indicate that CM current due to unsymmetrical network does cause radiation and the magnitude of radiation depends on the magnitude of CM current. Also, bending the transmission line to an angle increases radiation with maximum radiation observed at 10 degree and minimum at 50 degree. The effect of frequency signal on BPLC indicates that the higher the frequency, the higher the line radiated signal with maximum radiation at 55 MHz.
