What is Synchronous Condenser ?

Synchronous Condenser Definitio

A synchronous condenser is defined as a synchronous motor running without a mechanical load, used to improve the power factor of power systems.

Improving Power Factor

It draws a leading current when over-excited, which helps balance the lagging current from inductive loads.

Three-Phase System Usage

In a three-phase system, the synchronous motor operates at no load to improve the overall power factor by adjusting the current angle.

Synchronous Condenser Advantage

Smooth, continuous control of the power factor

Synchronous Condenser Disadvantage

The system is not silent since the synchronous motor has to rotate continuously.

Economic Considerations

Synchronous condensers are economical for large power networks but less so for systems below 500 kVAR, where capacitor banks are preferred.

Smooth Control

Synchronous condensers provide smooth, continuous power factor adjustment, unlike capacitor banks, which adjust in steps.

Battery charging process using AC adapter

Battery charging process using AC adapter

The process of charging the battery using the AC adapter is as followsConnecting devicePlug the AC adapter into the power outlet, making sure the connection is secure and stable. At this point, the AC adapter starts to obtain AC power from the grid.Connect the output of the AC adapter to the device that needs to be charged, usually through a specific charging interface or data cable.Ac adapter operationInput AC conversionThe circuit inside the AC adapter first rectifies the input AC power, conve

The circuit working principle of one-way switch

The circuit working principle of one-way switch

A one-way switch is the most basic type of switch that has only one input (often called the "normally on" or "normally closed" state) and one output. The working principle of the one-way switch is relatively simple, but it has a wide range of applications in various electrical and electronic devices. The following details the circuit working principle of the one-way switch:The basic structure of a one-way switchA one-way switch usually consists of the following parts: Contact: A metal part used

What is the effect of applying alternating current to a DC machine?

What is the effect of applying alternating current to a DC machine?

Applying alternating current to a DC motor can have a variety of adverse effects because DC motors are designed and operate to handle direct current. The following are the possible effects of applying AC to a DC motor:Cannot start and run properly No natural zero crossing: AC has no natural zero crossing to help the motor start, while DC motors rely on constant direct current to establish a magnetic field and start. Inversion phenomenon: The sinusoidal waveform of alternating current changes dir
