Binary Arithmetic
Binary Addition Rules Arithmetic rules for binary numbers are quite straightforward, and similar to those used in decimal arithmetic. The rules for addition of binary numbers are: Figure 1.Rules for…
Amplifier Parameters
Amplifier Parameters Any amplifier is said to have certain parameters. These are the particular properties that make the amplifier perform in a certain way, and so make it suitable for…
Amplifier Gain & Decibels
Amplification The Voltage Amplification (Av) or Gain of a voltage amplifier is given by: With both voltages measured in the same way (i.e. both RMS, both Peak, or both Peak…
Amplifier Bandwidth
Controlling Bandwidth Any amplifier should ideally have a bandwidth suited to the range of frequencies it is intended to amplify, too narrow a bandwidth will result in the loss of…
Protection System in Power System
This portion of our website covers almost everything related to protection system in power system including standard lead and device numbers, mode of connections at terminal strips, color codes in…
Stator Earth Fault Protection of Alternator
This is to be noted that, the star point or neutral point of stator winding of an alternator is grounded through an impedance to limit the ground fault current. Reduced…
Small and Large Motor Protection Scheme
The electric motor is most essential drive in modern era of industrialization. From fractional hp AC motor used for different home appliances to giant synchronous motor and induction motor of…
Rotor Earth Fault Protection of Alternator or Generator
The rotor of an alternator is wound by field winding. Any single earth fault occurring on the field winding or in the exciter circuit is not a big problem for…
Overvoltage Protection
There are always a chance of suffering an electrical power system from abnormal over voltages. These abnormal over voltages may be caused due to various reason such as, sudden interruption…
Motor Thermal Overload Protection
For understanding motor thermal overload protection in induction motor we can discuss the operating principle of three phase induction motor. There is one cylindrical stator and a three phase winding…
