  2. IEC 61508 - Wikipedia

    en.wikipedia.org/wiki/IEC_61508

    IEC 61508 is an international standard published by the International Electrotechnical Commission (IEC) consisting of methods on how to apply, design, deploy and maintain automatic protection systems called safety-related systems.

  3. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface. Substances that flow become essentially horizontal in their containers (or other physical boundaries) because of gravity whereas most bulk solids pile at an angle of repose to a ...

  4. Electrical system design - Wikipedia

    en.wikipedia.org/wiki/Electrical_system_design

    Electrical system design is the design of electrical systems. This can be as simple as a flashlight cell connected through two wires to a light bulb or as involved as the Space Shuttle. Electrical systems are groups of electrical components connected to carry out some operation.

  5. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    A lighting control system incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces. Lighting control systems are sometimes ...

    en.wikipedia.org/wiki/Dynamic_line_rating_for...

    Dynamic line rating (DLR), also known as real-time thermal rating (RTTR), is an electric power transmission operation philosophy aiming at maximizing load, when environmental conditions allow it, without compromising safety. Research, prototyping and pilot projects were initiated in the 1990s, but the emergence of the "smart grid" stimulated ...

    en.wikipedia.org/wiki/Instrumentation_and...

    Instrumentation and control engineering. Instrumentation and control engineering (ICE) is a branch of engineering that studies the measurement and control of process variables, and the design and implementation of systems that incorporate them. Process variables include pressure, temperature, humidity, flow, pH, force and speed.

  8. Electronic system-level design and verification - Wikipedia

    en.wikipedia.org/wiki/Electronic_system-level...

    Electronic system level (ESL) design and verification is an electronic design methodology, focused on higher abstraction level concerns. The term Electronic System Level or ESL Design was first defined by Gartner Dataquest, an EDA-industry-analysis firm, on February 1, 2001. [1] It is defined in ESL Design and Verification [2] as: "the ...

  9. Intelligent electronic device - Wikipedia

    en.wikipedia.org/wiki/Intelligent_electronic_device

    IEDs receive data from sensors and power equipment and can issue control commands, such as tripping circuit breakers if they sense voltage, current, or frequency anomalies, or raise/lower tap positions in order to maintain the desired voltage level.
