A waveguide junction circulator used as an isolator by placing a matched load on port 3. The label on the permanent magnet indicates the direction of circulation. Microwave circulators fall into two main classes: differential phase shift circulators and junction circulators, both of which are based on cancellation of waves propagating over two different paths in or near magnetized ferrite ...
Safety regulations of the utility must prevent any attempt to open the disconnector while it supplies a circuit. Standards in some countries for safety may require either local motor isolators or lockable handles (which can be padlocked). IEC standard 62271-102 defines the functionality and features of a disconnector.
A battery isolator is an electrical device that divides direct current (DC) into multiple branches and only allows current in one direction in each branch. The primary benefit of such an arrangement is the ability to simultaneously charge more than one battery from a single power source (e.g., an alternator) without connecting the battery terminals together in parallel.
For a λ/4 coupled-line the total delay length is λ/2 so the second signal is inverted and this gives a maximum response on the coupled port. [18] A single λ/4 coupled section is good for bandwidths of less than an octave. To achieve greater bandwidths multiple λ/4 coupling sections are used.
Barrier isolator, a device that provides a physical barrier between a laboratory technician and a work process; Optical isolator, a directional device in optical fiber communications; Opto-isolator, a directional device in electronics; Vibration isolator, any of various devices to isolate connected parts of an assembly from each other's vibrations
A typical strain insulator is a piece of glass, porcelain, or fiberglass that is shaped to accommodate two cables or a cable shoe and the supporting hardware on the support structure (hook eye, or eyelet on a steel pole/tower). The shape of the insulator maximizes the distance between the cables while also maximizing the load-bearing transfer ...
An isolator is a two-port device that transmits microwave or radio frequency power in one direction only. The non-reciprocity observed in these devices usually comes from the interaction between the propagating wave and the material, which can be different with respect to the direction of propagation.
Everlight EL817 phototransistor opto-isolator in DIP-4 package Halo TG110-S050N2RL 10/100BASE-TX Ethernet pulse transformer in SO-16 package, with the underside shown on the right. Galvanic isolation is a principle of isolating functional sections of electrical systems to prevent current flow; no direct conduction path is permitted.
