Calibration of Instrument Current Transformers with Atypical Secondary Current
− Methods enabling a determination of errors εI and δI for a high transformation ratio difference between a standard and tested instrument current transformers (ICT) are described in this article. A widespread method uses an automatic transformer test set for the measurement of a difference between a standard and tested ICT. A method transforming secondary currents to voltages and an indirect m...
متن کاملThe nuclear microprobe: a unique instrument
There are several features characterising high-energy ion interactions with matter which enables techniques which utilise the high-energy ion beam to have unique or advantageous characteristics. (i) The lack of primary particle bremsstrahlung enables Particle Induced X-ray Emission (PIXE) to be carried out with very little X-ray background, and therefore correspondingly high analytical sensitiv...
متن کاملA portable energy-sensitive cosmic neutron detection instrument.
The construction and testing of a portable energy-sensitive neutron instrument are described. This instrument has been designed and constructed for the primary purpose of characterizing cosmic-ray neutron fields in the upper atmosphere and in cosmic reference field facilities. The instrument comprises a helium-3 proportional counter surrounded by 15 mm of lead and 140 mm of polyethylene creatin...
متن کاملLipopolysaccharide-sensitive H+ current in dendritic cells.
Dendritic cells (DCs) are the most potent antigen-presenting cells equipped to transport antigens from the periphery to lymphoid tissues and to present them to T cells. Ligation of Toll-like receptor 4 (TLR4), expressed on the DC surface, by lipopolysaccharides (LPS), elements of the Gram-negative bacteria outer wall, induces DC maturation. Initial steps of maturation include stimulation of ant...
