    Terminal Faults. Usually the short-circuit current is inductive in nature, and the re-strike voltage appearing across the contacts at the instant of arc interruption is characterized by high frequency oscillations in the order of a few hundred cycles. Short Line Faults (SLF) Short-circuit faults occurring on a line length between 0.5 to 5 km are termed as s hort line faults or kilometric faults. A fault of this type imposes a highly onerous duty on the circuit breaker, thereby affecting its interrupting ability. Transformer Magnetizing and Reactor Currents. The transformer no-load current and the reactor current impose severe stresses on the circuit breaker upon their interruption because of the low magnitude of these inductive currents. Energization of Long Transmission Lines. When an initially uncharged, unloaded long line is charged, then over-voltages to the order of twice the normal voltage are impressed, imposing an onerous duty on the power system.

  • What is SF6 Circuit Breaker? Construction, Working Principle

    Gas System – The closed circuit gas system is employed in SF 6 circuit breakers. The SF 6 gas is costly, so it is reclaimed after each operation. This unit consists low and high-pressure chambers with a low-pressure alarm along with warning switches. When the pressure of the gas is very low due to which the dielectric strength of gases decrease and an arc quenching ability of the breakers is endangered, then this system gives the warning alarm.

    The dielectric strength of SF6 increases with pressure so smaller breakers can be used at higher voltages. The breakers have a smaller footprint, so they use less real estate which can be very expensive. They are very reliable and require less maintenance than air blast or oil breakers and can operate at higher voltages effectively.
