C, S, & P III Types of Overcurrents

Horizontales
A condition results in an excessive current relative to normal operating current, but one that is confined to the normal conductive path
A ______ short-circuit condition represents a “solid” (bolted or welded) connection of relatively low imped- ance (assumed to be zero)
Fault currents resulting from ____-__-______ bolted short-circuit conditions can range from 25% to 125% of the 3-phase value, depending upon the distance from the generator or transformer
The largest amount of current capable of being delivered at a point on the system during a short-circuit condition
A type of short-circuit condition having an unintentional connection between an ungrounded conductor and a non–current carrying conductor, metallic equipment, or earth
A ____-__-____ bolted short-circuit condition results in fault current that is approximately 87% of the fault current for a 3-phase bolted short-circuit condition
Verticales
______ _______devices (OCPDs), such as fuses and circuit breakers, are intended to protect conduc- tors and equipment from the effects of potentially harmful overcurrents
Because of the low impedance path, a _____-_____ bolted short-circuit condition is typically assumed to be the highest magnitude of fault current
The fault current of an ______ short-circuit condition is always less than the available fault current value of a bolted short-circuit condition at a specific location
Harmless overloads are routinely caused by temporary ______ or starting currents
A condition that results in fault current that flows outside the normal conducting path at some point on the circuit
Either an overload condition or a short-circuit condition
