Switchboards

marine

A switchboard which is directly supplied by the main source of electrical power and is intended to distribute electrical energy to the ship service, (SOLAS).

Switched power supply

energy

A switched power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

Switchgear

energy

Switchgear is a switch used to make or break an electrical connection. Switchgear comes in various sizes depending on the voltages of the electrical circuit. Essentially the same as a domestic light switch but for higher voltage applications.

Switching station

energy

A switching station is a substation without transformers and operating only at a single voltage level.

Synchronization

energy

In an alternating current electric power system, synchronization is the process of matching the frequency of a generator or other source to a running network.

Synchronous condenser

energy

A DC-excited synchronous motor, whose shaft is not connected to anything but spins freely.

Synchrophasor

energy

Time synchronized measurements made up of an angle measurement and a magnitude measurement from a Phasor measurement unit.

Synchroscope

energy

In AC electrical power systems, a synchroscope is a device that indicates the degree to which two systems (generators or power networks) are synchronized with each other.

SYNCROLIFT® shiplifts

marine

A ship lift consisting of an articulated platform: a series of transverse beams supported on each end by electro-mechanical hoists and connected longitudinally by non-rigid structural members.

Synfuel

marine

Synfuels can be produced from coal, natural gas, or biomass feed stocks through chemical conversion into syncrude and/or synthetic liquid products.

Synroc

energy

Synroc, (synthetic rock), is a means of safely storing radioactive waste.

Synthetic fuels

energy

A fuel that is manufactured as opposed to naturally existing fossil fuels. Synthetic fuels, or commonly known as Synfuel, are made by combining hydrogen, produced from water, and the greenhouse gas CO2.

System

energy

A system is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole.

System grounding

energy

System grounding is required for use in systems like utility distribution systems, telecommunications systems, and in commercial/residential buildings where any significant metal system must be bonded together and referenced to the earth at one point.

Systems engineering

energy

Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles.

Systems theory

energy

Systems theory is the interdisciplinary study of systems, which are cohesive groups of interrelated, interdependent parts that can be natural or human-made.
