Technical FAQs 4
What is a circuit breaker in a substation?
A circuit breaker in substation is a key component in electrical power systems, designed to interrupt the flow of electricity when a fault occurs, such as a short circuit or overload. Depending on system design, these devices can operate manually or automatically and come in various types, including air, vacuum, oil, and SF₆ gas.
What is the difference between OBC and SF6 arc Breakers?
Oil (OCB) use insulating oil to suppress arcs. They are more common in legacy systems and require ongoing maintenance due to oil degradation. SF₆: These breakers, employed in high-voltage substations, use sulphur hexafluoride gas for superior arc quenching and insulation.
Why are arrester placement & TRV synchronized in HV substations?
Restrike / Reignition: if the dielectric recovery after current zero is insufficient for the TRV applied, the arc can re-ignite, giving multiple arc events and large transient currents—this is a key reason why arrester placement and TRV capability are tightly coordinated in HV substations.
What is a TRV breaker?
TRV is the voltage that appears across breaker terminals immediately after interruption and during the short transient interval before the network settles to power-frequency values.
