When a system has too many radial lines protection using time delay overcurrent relay becomes impractical. This problem can be solved to an extent by using distance relays. Distance relays uses voltage and current to calculate the. Distance relay protection has been defined as a part of relay protection in power systems that detects and isolates faults based on the distance between the relay and fault points. Unlike overcurrent relays, which only respond to the magnitude of current, a distance relay measures the impedance of. Such relays are called Distance Relays or Impedance Relays. In an impedance relay, the torque produced by a current element is opposed by the torque produced by a voltage element. The relay will operate when the ratio V/I is less than a predetermined value.

Beam splitters are classified by construction (plate, cube, pellicle, polka dot) and by function (standard, non-polarizing, polarizing, dichroic). Construction determines ghosting, damage threshold, and form factor. Function determines how polarization and wavelength are. Beamsplitters are optical components used to split incident light at a designated ratio into two separate beams. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction: cube or plate. A beam splitter (or beamsplitter, power splitter) is an optical device which can split an incident light beam (e. a laser beam) into two (or sometimes more) beams, which may or may not have the same optical power (radiant flux). It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications.
