Relay Presentation PPT by G@nesh SlideShare RELAY A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relay have two switch positions and most have double throw (changeover) switch contacts. PowerPoint Presentation Relay we use has a single switch that is normally open (N.O.) refers to the effect of the switch in its normal (non energized state) Electric symbol we use for these relays the symbol shows the coil and switch Why Use Relays? When the coil is not energized a spring keeps the switch held open or OFF. Relays SlideShare • A type of relay that can handle the high power required to directly control an electric motor or other loads is called a contactor. 4. PRINCIPLE • A relay may also be called an “electromagnetic switch” • Relays use a “low amperage circuit” to control a “high amperage circuit” • The low amperage circuit controls an electromagnetic device. Relay Seminar Report with PPT and PDF Free Download Sumit Thakur Mechanical Relay Seminar Report with PPT and PDF Free Download: An electrical switch which uses an electromagnet to move a switch from off position to on position instead of using a person to move switch is called as a relay. Very less amount of power is utilized in turning on... 1.

Regulating relays are the switches that contacts such that voltage boosts up as in the case of tap changing transformers. Auxiliary contacts are used in circuit breakers and other protective equipment for contact multiplication. Monitoring relays monitors the system conditions such as direction of power and accordingly generates the alarm. Electrical Symbols — Switches and Relays | Home Electrical ... Basic Electrical Symbols Ppt. ConceptDraw. ... A relay is a switch that is operated by electricity. Switches are made to handle a wide range of voltages and currents; very large switches may be used to isolate high voltage circuits in electrical substations. Electrical Relay and Solid State Relays for Switching Electrical Relay Contact Types. As well as the standard descriptions of Normally Open, (NO) and Normally Closed, (NC) used to describe how the relays contacts are connected, relay contact arrangements can also be classed by their actions.Electrical relays can be made up of one or more individual switch contacts with each “contact” being referred to as a “pole”.

Relay Basics 101 Rattlebars Relay Basics 101 By Chet Walters. A relay works this way: Your switch "turns on" the relay. The relay "turns on" your accessory. A relay draws very little current through your switch (milliamps) which protects your switch from burnout. The when "turned on" relay can switch a much larger current (30 amps) and not burn out.
