A synchroscope is a device within an AC electrical power system that indicates the amount to which two systems like; power networks or generators are synchronized. These two systems should work at a similar frequency & the phase angle for the two power systems to be synchronized in between the systems should be zero. So these devices are useful in measuring & displaying the frequency variation and phase angle between two power systems. When these … [Read more...]
Electromagnetic Relay : Construction, Working, Circuit, Types & Its Applications
A relay is an electrically operated switch that either opens or closes an electrical circuit. Generally, Relays have an induction mechanism at the input part that reflects certain input variables like; voltage, current, power, frequency, impedance, temperature, speed, pressure, etc. It has an actuator at the output part that can understand the ON & OFF control of the controlled circuit. There is an intermediate mechanism between the input & output … [Read more...]
Seebeck Effect : Formula, Differences, Coefficients, Example, Advantages & Its Applications
In the year 1821, German Physicist namely ‘Thomas Seebeck noticed various thermoelectric effect properties. He noticed that an electrical circuit with two dissimilar metals with different temperatures created an EMF at their junctions. Thomas Seebeck observed that the compass needle deflected when he created a closed loop between two different metals, forming a thermocouple. The circuit generates a current known as the thermoelectric current. Previously, … [Read more...]

Solid State Relay : Block Diagram, Circuit, Working, Types, Differences & Its Applications
Generally, both electromechanical and solid-state relays are similar, but solid-state relays electrically isolate the low-voltage input from the output that simply switches and controls an electric load. Electro-mechanical relays have a limited contact life cycle, so they have slower switch speeds, particularly in contractors and large power relays, whereas solid-state relays do not have such limitations. The solid-state relay (SSR) doesn’t have any moving … [Read more...]
Cycloconverter : Circuit, Working, Types, Control Strategies, Characteristics & Its Applications
A power supply is used to change the electric current from a source to the voltage, frequency & current to power the electric load. Sometimes these are called electric power converters. Power supply is classified into two categories; AC & DC power supply. We know that AC power is more economical and it can be used for transmission thus most of the electrical devices or machines run on AC power.
