  2. Transfer switch - Wikipedia

    en.wikipedia.org/wiki/Transfer_switch

    A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a switch, while others are automatic and trigger when they sense one of the sources has lost or gained power. An Automatic Transfer Switch (ATS) is often installed where a ...

    The "Firetrol" branch of ASCO provides power transfer switches, controls, and alarms for fire suppression. ASCO's headquarters is located in Florham Park, New Jersey . With over 1400 employees and 500,000 square feet of manufacturing floor space, it is the world's largest manufacturer of power transfer switches.

  4. Generator interlock kit - Wikipedia

    en.wikipedia.org/wiki/Generator_Interlock_Kit

    It is a less-expensive alternative to purchasing and installing a dedicated transfer switch. The kit achieves the same function by adding an external interlock onto an existing breaker panel that allows the main breaker to be turned on or one designated load breaker to be turned on, but not both at the same time. The interlocked load breaker is ...

  5. Uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    It is common for the autotransformer to cover a range only from about 90 V to 140 V for 120 V power, and then switch to battery if the voltage goes much higher or lower than that range. In low-voltage conditions the UPS will use more current than normal, so it may need a higher current circuit than a normal device.

  6. Static relay - Wikipedia

    en.wikipedia.org/wiki/Static_relay

    In electrical systems, a static relay is a type of relay, an electrically operated switch, that has no moving parts. [1] Static relays are contrasted with electromechanical relays, which use moving parts to create a switching action. Both types of relay control electrical circuits through a switch that is open or closed depending upon an ...

  7. Static synchronous compensator - Wikipedia

    en.wikipedia.org/wiki/Static_synchronous_compensator

    In Electrical Engineering , a static synchronous compensator (STATCOM) is a shunt-connected, reactive compensation device used on transmission networks. It uses power electronics to form a voltage-source converter that can act as either a source or sink of reactive AC power to an electricity network.

  9. Proportional–integral–derivative controller - Wikipedia

    en.wikipedia.org/wiki/Proportional–integral...

    Tuning a control loop is the adjustment of its control parameters (proportional band/gain, integral gain/reset, derivative gain/rate) to the optimum values for the desired control response. Stability (no unbounded oscillation) is a basic requirement, but beyond that, different systems have different behavior, different applications have ...
