The energy systems language of systems ecology. The energy systems language, also referred to as energese, or energy circuit language, or generic systems symbols, is a modelling language used for composing energy flow diagrams in the field of systems ecology.
23 – Temperature control device, Heater; 24 – Volts per Hertz Relay (in some old analog applications, a 59 and an 81 device would be chained together as a 59/81 to implement the equivalent of V/Hz protection) 25 – Synchronizing or Synchronism-check Device; 26 – Apparatus Thermal Device, Temperature Switch; 27 – Undervoltage Relay
Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
IEC 750-1983 (AS 3702 is equivalent, but provides extra information.) IEEE 315-1975 / ANSI Standard Y32.2. Annex F: "Cross reference list of Class Designation Letters" compares IEC 113-2:1971 to the IEEE/ANSI standard. * AS 1102 and IEC 60617 for "Graphical Symbols for Electrotechnology".

A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip, often encased in a tubular glass bulb to protect it from dust or short circuit. Another common design ...
