Abstract Impedance measurements of building materials have been gaining popularity especially in the last twenty years. No electrical component has only resistance, capacitance or inductance, as there is an interplay these parameters. This compounded case materials, which contain a significant number different phases that vary chemical composition, crystalline structure and properties. It is, t...

A voltage transformer, as voltage signal detection equipment, plays an important role in a power system. Presently, more and more electric power systems are adopting potential transformer and capacitance voltage transformers. Transformers are often large in volume and heavyweight, their insulation design is difficult, and an iron core or multi-grade capacitance voltage division structure is gen...

High resolution (Doppler-resolved) measurement of Doppler-shifted ion absorption frequencies allows the determination of the electric field responsible for the shift. A new method based on velocity modulation laser spectroscopy is described for the nonperturbative measurement of the axial electric fields in glow discharges. The A ‘n, + X I&+ (4.0 ) band of NT has heen used as a probe of a He/N,...

Abstract Research has been carried out to identify the potential for soil corrosion design of cathodic gas pipeline protection system. The research location is in Cimanggis - Bitung, West Java, which located at coordinates 6°19’00 “- 6°28’00” South Latitude and 106°43’00 106°55’30” East Longitude. Measurement resistivity using Wenner method refers ASTM G37, with variations distance 0.75m, 1.50m...
