  • Relay Protection Directional Protection Principle

    Relay Protection Directional Protection Principle

    Directional relays are protective devices that isolate faults in power systems by detecting the direction of fault currents. As an essential. Each Cahier Technique provides an in-depth study of a precise subject in the fields of electrical networks, protection devices, monitoring and control and industrial automation systems. The latest publications can be downloaded on Internet from the Schneider server. The PR123/P and the PR333/P units carry out excludable directional protection (“D”) against short-circuit with. Protection equipment has the basic role of detecting an electrical fault and disconnecting that part of the network in which the fault occurs limiting the size of the disconnected section as far as possible.


  • Principle of Linear Analog Optical Couplers

    Principle of Linear Analog Optical Couplers

    Linear Optocouplers features an infrared LED optically coupled with two photodiodes. One input-side feedback photodiode is used to generate a control signal that provides a servomechanism to the LED drive current, thus compensating for the LED's nonlinear time and temperature. This application note presents isolation amplifier circuit designs useful in industrial test and measurement systems, instrumentation, and communication systems. It can be used to isolate analog. An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can. This has been traditionally accomplished by means of transformers and optocou-plers with transformers being used to couple AC signals and optocouplers used primarily for DC signal cou-pling. Opto-isolators prevent high voltages from affecting the system receiving the signal.

  • What is DLC Digital Fiber Optic Connector

    What is DLC Digital Fiber Optic Connector

    The Duplex LC connector is a small form-factor fiber optic connector that supports two fibers in a single housing. It is designed to provide high-density connectivity while maintaining excellent optical performance. The fiber connector types, sometimes referred to as terminations, link fiber optic cables together through terminals, switches, adapters, and patch panels, by bridging the gap between their. An SFP duplex LC connector is a fiber optic interface used in many small form-factor pluggable (SFP) optical transceivers to enable full-duplex optical communication.
