fault current उदाहरण वाक्य

उदाहरण वाक्य

1. A fault current limiter is a nonlinear element which has a low impedance at normal current levels, but presents a higher impedance at fault current levels.
2. Low resistance grounding systems will have a time rating ( say, 10 seconds ) that indicates how long the resistor can carry the fault current before overheating.
3. A neutral current transformer is used as earth fault protection to measure any fault current flowing through the neutral line from the wye neutral point of a transformer.
4. To make the ground fault current easier to detect, the grounding resistor of the system may be switched between two values so that the fault current pulses.
5. To make the ground fault current easier to detect, the grounding resistor of the system may be switched between two values so that the fault current pulses.
6. While the fault current from a distribution or transmission system can usually be calculated or estimated with precision, calculation of the earth grid resistance is more complicated.
7. If testing a vacuum tube radio, or a fused circuit in a house, there is an upstream fuse or breaker which would limit the fault current.
8. When very large fault currents are injected into the earth, the area around the point of injection may rise to a high potential with respect to distant points.
9. Early applications will be where the benefit of smaller size, lower weight or the ability to rapidly switch current ( fault current limiters ) outweighs the added cost.
10. The leakage reactance ( usually about 5 to 10 % of the full load impedance ) helps limit both the magnitude and rate of rise of the fault current.
