SUBSTATION TYPICAL SUBSTATION LAYOUT What is Substation? A substation is an important part of Electric power system. Substation performs many operations like voltage Step-up & Step-Down, measurement of electric quantities, controlling,…., etc.                              OR A substation is an assembly of many electric components connected in series or parallel at one specified distance for stepping up or stepping Down the electrical quantities and measurement and controlling of electric quantities. It may include power generation substation , Power transmission substation And power Distribution Substation . Main Components of Substation Ø Power transformer Ø Circuit breaker Ø Isolator Ø Lighting Arrestor Ø Relay Ø Capacitor bank Ø Earthing Ø Bus-Bar Ø Instrument Transformer Ø Conductors & insulators 1.     Power Transformer POWER TRANSFORMER “ Transformer is a static device which is used to step-up

Basics of Servo Motor and Its Types

  A servo motor is a rotary actuator or a motor that allows for precise control in terms of the angular position, acceleration, and velocity. Basically, it has certain capabilities that a regular motor does not have. Consequently, it makes use of a regular motor and pairs it with a sensor for position feedback Block Diagram of Servo Motor Basics of Servo Motor A servo motor is a rotary actuator or a motor that allows for a precise control in terms of the angular position, acceleration, and velocity. Basically it has certain capabilities that a regular motor does not have. Consequently it makes use of a regular motor and pairs it with a sensor for position feedback.  The servomotor includes the motor that drives the load and a position detection component, such as an encoder. The servo system vary the controlled amount, such as position, speed, or torque, according to the set target value (command value) to precisely control the machine operation. Types of servo motor

Basics of Transformer

Transformer Basics Basic Transformer Construction Definition-           Transformer is static device which converts one electrical energy to another electrical energy (voltage/current) by means of flux without change in frequency. Working Principal-           Transformer works on the principal of Faradays law of “Mutual Induction” Which States that “When two electrically isolated coils place near to each other and energy voltage/current flowing through the coil. An flux produce in primary coil and that fluxed which are sinusoidal in nature cut by secondary coil and EMF is induced in secondary coil. Basic Construction-           Transformer has following main three parts namely as “primary coil, core, secondary coil” primary and secondary coil are mounted on same core but electrically separated from each other. Types-           In Electrical Engineering the most famous transformers are “Step UP and Step Down” and these are under category of Voltag
