WebIn semiconductor devices, leakage is a quantum phenomenon where mobile charge carriers (electrons or holes) tunnel through an insulating region. Leakage increases exponentially as the thickness of the insulating region decreases. Tunneling leakage can also occur across semiconductor junctions between heavily doped P-type and N-type semiconductors. Web11 de set. de 2024 · By installing a Residual Current Device (RCD) in the circuit, the earth leakage current must be considered. For luminaires, the typical earth leakage current is less than 1 mA. This means that a large number of LED luminaires can be installed. You also need to consider the distortion of the sinusoidal waveform.
