Electrical-surface leakage

Electrical equipment With electrical equipment, e.g. PCE equipment or motors, even low voltages may produce electric sparks (e.g. when opening or shutting electrical circuits). Leakage currents and hot surfaces may be sources of ignition, too. Provide for efficient protective measure by following pertinent technical standards... 

The nature of bulk defects is straightforward. Pinholes, cracks, or other surface imperfections result in rapid diffusion of saline into the implant resulting in corrosion of electrical conductors. This corrosion lowers the resistance of the original leakage path until normal operation of the electronic circuit is impared and the Implant falls. 

Surface layers of silicon oxide are important in semiconductor device fabrication as interlayer dielectrics for capacitors, isolation of conducting layers, or as masking materials. However, anodic oxides, due to their relatively poor electrical properties, breakdown voltage, and leakage current, have not yet found much use in device technology, and cannot compete with thermal oxides obtained at high temperatures of 700 to 900 °C.
