Peak Voltage Measurements Using Standard Sphere Gap Method

Abstract

The paper presents a measurement system of peak value of high voltage (H.V.) using 150 mm diameter sphere gap, disposed in vertical position. Experimental breakdown results have been compared with standard values at atmospheric reference conditions STC (20°C, 101.3 kPa, or 760 mmHg). The main experimental and theoretical characteristics are presented.

Are Cape Cormorants Phalacrocorax capensis losing the competition? Dietary overlap with commercial fisheries

“…Each survey was a series of predetermined parallel transects that were randomly-spaced within each pre-defined stratum (see Figure 3b; Barange, et al, 1999;Roy et al, 2007;. Along each transect, back-scattering intensity was estimated using a SIMRAD echo-sounder, pre-calibrated using the standard sphere gap technique (Barange and Hampton, 1997;Barange, et al, 1999;Ungureanu and Nemțoi, 2014) and processed using echo-integration software (DAFF, 2016). Mid-water trawl samples were conducted to determine the size (caudal length) distributions of surveyed populations.…”
