The primary arc
of the story, written in a firstperson conversational style, describes a singularly eventful night spent on alert with the surprise of an early morning scramble and subsequent hours of tension waiting in the cockpit for a launch order.
Primary arc is quenched by opening high voltage breakers completely.
When a short circuit occurs between the insulator and the ground, an intense short circuit current passes through the primary arc during the fault continuation, thus the arc does not last long and its voltage appears at the two sides of the main column.
where gp is the primary arc time variable conductance, Tp is the constant of time and Gp is the primary arc conductance that can be considered as the static property of the arc and is defined as follows:
where Lp is arc length, Vp is the parameter of voltage per primary arc length unit and i is the arc current.
In this experiment, however, the primary arc
beads that were formed between two PVC-wounded copper wires in a half-obturator, when brought in contact with each other.
In a double rainbow, a second arc may be seen above and outside the primary arc
and has the order of its colours reversed.
The former phenomenon arises due to coupling with healthy phases even after the primary arc has ceased and has a characteristic waveform presents the typical secondary.
The arc model produces the primary arc and secondary arc.
The first is the reduction of dislocation rates by modeling acetabular component orientation and then recreating a maximum primary arc of impingement-free motion.
He can also increase the primary arc of motion, as well as re-direct this primary arc to maximize the functional arc.
By moving his hand, the surgeon can view a simulation of the resulting primary arc of motion.
