2. Current limiting - Wikipedia

   en.wikipedia.org/wiki/Current_limiting

   Current limiting is the practice of imposing a limit on the current that may be delivered to a load to protect the circuit generating or transmitting the current from harmful effects due to a short-circuit or overload. The term "current limiting" is also used to define a type of overcurrent protective device.

3. Breaking capacity - Wikipedia

   en.wikipedia.org/wiki/Breaking_capacity

   Types used in commercial and industrial low-voltage distribution systems are rated to safely interrupt 200,000 amperes. The rating of power circuit breakers varies according to the application voltage; a circuit breaker that interrupts 50,000 amperes at 208 volts might be rated to interrupt only 10,000 amperes at 600 volts, for example.

4. Prospective short-circuit current - Wikipedia

   en.wikipedia.org/wiki/Prospective_short-circuit...

   An isolated generator may be specially designed to ensure that it can source enough current on a short circuit to allow subordinate overcurrent protection devices to operate properly. Where an industrial system is fed from an electrical utility, the short circuit level at the point of connection may be specified, often with minimum and maximum ...

5. Inrush current - Wikipedia

   en.wikipedia.org/wiki/Inrush_current

   Alternating-current electric motors and transformers may draw several times their normal full-load current when first energized, for a few cycles of the input waveform. Power converters also often have inrush currents much higher than their steady-state currents, due to the charging current of the input capacitance .

6. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   At that instant, the circuit breaker connecting the generator to the system may be closed and the generator will then stay in synchronism with the system. [3] An alternative technique used a similar scheme to the above except that the connections of two of the lamps were swapped either at the generator terminals or the system terminals.

7. Engine–generator - Wikipedia

   The tie-in panel may also contain a phase rotation indicator (for 3-phase systems) and a circuit breaker. Camlock connectors are rated for 400 amps up to 480-volt systems and used with 4/0 type W cable connecting to the generator. Tie-in panel designs are common between 200- and 3000-amp applications.

9. Capability curve - Wikipedia

   en.wikipedia.org/wiki/Capability_curve

   Due to high cost of a generator, a set of sensors and limiters will trigger the alarm when the generator approaches the capability-set boundary and, if no action is taken by the operator, will disconnect the generator from the grid. [3] D-curve expands with cooling. The D-curve for a particular generator can be expanded by improved cooling.
