Partial Discharge in Liquid Nitrogen

Yield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation

Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...

Prebreakdown events in liquid nitrogen

2014 It was shown previously that a small volume of liquid nitrogen in front of a sharp metal tip can withstand an extremely high field without any sign of breakdown or charge injection. Subsequently, the influence of the tip radius on the critical field has been investigated and is described here. Also, by monitoring the injection, it has been possible to analyse the influence of the injected ...

Partial Discharge Detection in Solid Dielectrics

Partial Discharge (PD) measurement and characterization provide vital information on insulation condition, different aspects of insulation ageing useful for equipment integrity verification and diagnosis. The work demonstrates standard test methods which employs capture of PD parameters with the aid of discharge detector. This paper investigates on the voltage amplitude at which PD of a specifi...
