2. Recloser - Wikipedia

   en.wikipedia.org/wiki/Recloser

   Each sectionalizer detects and counts fault current interruptions by the recloser (or circuit breaker). After a pre-determined number of interruptions, the sectionalizer will open, thereby isolating the faulty section of the circuit, allowing the recloser to restore supply to the other non-fault sections.

3. Substation - Wikipedia

   en.wikipedia.org/wiki/Transformer_substation

   The arrangement of switches, circuit breakers, and buses used affects the cost and reliability of the substation. For important substations a ring bus, double bus, or so-called "breaker and a half" setup can be used, so that the failure of any one circuit breaker does not interrupt power to other circuits, and so that parts of the substation ...

4. Circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Circuit_breaker

   Medium-voltage circuit breakers rated between 1 and 72 kV may be assembled into metal-enclosed switchgear line-ups for indoor use or may be individual components installed outdoors in a substation. Air-break circuit breakers replaced oil-filled units for indoor applications, but are now themselves being replaced by vacuum circuit breakers (up ...

6. Sulfur hexafluoride circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Sulfur_hexafluoride...

   Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other ...

7. Isolated-phase bus - Wikipedia

   en.wikipedia.org/wiki/Isolated-phase_bus

   The consequences of a two- or three-phase fault between the generator and the first circuit breaker are therefore much more serious and often result in severe damage to the busbars and nearby equipment. Isolated-phase bus is made in ratings from 3000 amperes to 45,000 amperes, and rated for voltages from 5000 volts up to about 35,000 volts.
