Differential Relay:Differential Protecting of transformers and generators from localised faults
 
01:40
Differential Relay is a type of protection relay (protecitve relay), Differential relay is very commonly used relay for protecting transformers and generators from localised faults.Differential relays are very sensitive to the faults occurred within the zone of protection but they are least sensitive to the faults that occur outside the protected zone. Most of the relays operate when any quantity exceeds beyond a predetermined value for example over current relay operates when current through it exceeds predetermined value. But the principle of differential relay is somewhat different. It operates depending upon the difference between two or more similar electrical quantities. How does Differential Relay Works - he differential relay is one that operates when there is a difference between two or more similar electrical quantities exceeds a predetermined value. In differential relay scheme circuit, there are two currents come from two parts of an electrical power circuit. These two currents meet at a junction point where a relay coil is connected. According to Kirchhoff Current Law, the resultant current flowing through the relay coil is nothing but summation of two currents, coming from two different parts of the electrical power circuit. If the polarity and amplitude of both currents are so adjusted that the phasor sum of these two currents, is zero at normal operating condition. Thereby there will be no current flowing through the relay coil at normal operating conditions. But due to any abnormality in the power circuit, if this balance is broken, that means the phasor sum of these two currents no longer remains zero and there will be non-zero current flowing through the relay coil thereby relay being operated. =========================================== Dear friends, support this channel http://hrvoje3d.com/support/ =========================================== Subscribe and give a support :) ✔ Subscribe https://www.youtube.com/user/chrvoje1 ✔ WEB http://www.hrvoje3d.com/ ✔ FACEBOOK https://www.facebook.com/Chrvoje1-engineering-606909579495110/ https://www.facebook.com/profile.php?id=100015365768626 ✔ TWITTER https://twitter.com/chrvoje1 ============================================= Thanks For Watching.......

Relay - Explained and animated A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal

Protection relay: Power system protection
 
11:20
Protection Relay or Protective Relay is a device designed to trip a circuit breaker when a fault is detected as matter of fact it is designe to protect power system. What is a Protection Relay? Protection relay is a smart device that receives inputs, compares them to set points, and provides outputs. Inputs can be current, voltage, resistance, or temperature. Outputs can include visual feedback in the form of indicator lights and/or an alphanumeric display, communications, control warnings, alarms, and turning power off and on. Protection or Protective Relay eliminate unnecessary trips, isolate faults, protect motors and breakers, and provide system information to help you better manage your system We differentiate Protection Relay types by function: * Overcurrent relay * Inverse Definite Minimum Time relay * Distance relay/Impedance relay * Differential relay * Directional relay * Synchronism check relay How does Protection Relay works and what are the types by funtion you can see in video. =========================================== Dear friends, support this channel http://hrvoje3d.com/support/ =========================================== Subscribe and give a support :) ✔ Subscribe https://www.youtube.com/user/chrvoje1 ✔ WEB http://www.hrvoje3d.com/ ✔ FACEBOOK https://www.facebook.com/Chrvoje1-engineering-606909579495110/ https://www.facebook.com/profile.php?id=100015365768626 ✔ TWITTER https://twitter.com/chrvoje1 ============================================= Thanks For Watching.......

The Buchholz Relay -Principle, construction and operation
 
02:49
This video is about operation and construction of Buchholz relay. Principle of buchholz relay Any fault occurring inside an oil immersed transformer is accompanied by decomposition of transformer oil into gases. Working of Buchholz relay Buchholz relays are protection equipment used in oil immersed transformers. It is used to sense the faults occurring in the transformer winding and core such as inter-turn faults, short circuits, earth faults, overheating of the core, oil leakage etc occurring inside a transformer. Basically, a Buchholz relay is an oil actuated relay. It gives an alarm or trips the input supply based on the level of oil inside it. It also responds quickly to the unusual oil flow from the transformer main tank to the oil conservator. Buchholz relays is a protection and monitoring equipment not only for transformers but also for oil immersed chokes with an oil conservator. www.electricalclassroom.com/buchholz-relay-buchholz-relay-principle-html/ More: http://www.electricalclassroom.com/ Like our facebook page: https://www.facebook.com/electricalclassroom/ Follow us on Twitter: https://twitter.com/Electricclassro Follow us on Google: https://plus.google.com/+Electricalclassroompage

Directional  Over-Current Relay: Directional over-current protection
 
01:54
Directional Over-Current protection comprises Over-Current Relay and power directional relay- in a single relay casing. Directional relay does not measure the power but is arranged to respond to the direction of power flow. How does Directional Relay works - Directional operation of relay is used where the selectivity can be achieved by directional relaying. The directional relay recognizes the direction in which fault occurs, relative to the location of the relay. It is set such that it actuates for faults occurring in one direction only. It does not act for faults occurring in the other direction. =========================================== Dear friends, support this channel http://hrvoje3d.com/support/ =========================================== Subscribe and give a support :) ✔ Subscribe https://www.youtube.com/user/chrvoje1 ✔ WEB http://www.hrvoje3d.com/ ✔ FACEBOOK https://www.facebook.com/Chrvoje1-engineering-606909579495110/ https://www.facebook.com/profile.php?id=100015365768626 ✔ TWITTER https://twitter.com/chrvoje1 ============================================= Thanks For Watching.......
