HV Components/CKE
High Voltage Lightning Arrestor
the arrestor is connected between system and ground in parallel with protected equipment. At continuous operating voltage, metal oxide arrestors appear to be an extremely high resistance, with the resistive current through the arrestor in the order of microamperes. In appearance of a lightning strike or switching surge on the system, the residual voltage across the arrestor will be limited to a certain permissible value because of the excellent non-linearity of arrestors. The high surge energy... (read more)

Why Advanced Oxidation Processes?
resources. Traces of organic / inorganic pollutants like NDMA, MTBE, 1,4-Dioxane, EDC ’s, etc. are often found in wastewater, ground water, and surface water. The reasons for the increasing degree of contamination are often due to industrialization, intensive agriculture practices, as well as all-round medical provisions for humans. Once these micropollutants enter the human food chain via drinking water, there is a long term risk to public health - even to human or animal genetic material... (read more)
