To show the full effect, the scope had to be set on a 500ms scale (right hand), or a 5X longer time base than the 100ms screen above on the left.

WHITE PAPER UNDERSTANDING TIME CURRENT CURVES 4/6 The next section of the curve moving up the time axis is the long time section. Long time settings cover the time range from 0.5 to 1000 seconds. The purpose of long time settings is to allow a time-based delay to elapse before tripping the circuit breaker for low level current faults.

the differences in readings (see curves, Figure 2). Tests by this method are sometimes referred to as absorption tests. Good insulation shows a continual increase in resistance (see curve D) over a period of time (in the order of 5 to 10 minutes). This is caused by the absorption; good insulation shows this charge effect over a time period much

Design Speed and Horizontal Curves Background: As Figure 3 shows, horizontal curves are circular arcs-i.e., a curve to the left or right-that connect straight sections of highway. On a horizontal curve, the design speed is used to determine acceptable ranges for the sharpness of curvature and how much the pavement surface is banked
