What is Power Factor?


Power Factor Definition


Power factor is defined as the ratio of real power used by a system to the apparent power transmitted through the circuit.

Understanding Reactive Power


Reactive power does no useful work itself, but it supports the active power in accomplishing useful work.


 

Power Factor Formula


The power factor is calculated as the cosine of the phase angle between the source voltage and current.

Power Factor Improvement Methods


  • Capacitor banks

  • Synchronous condensers

  • Phase advancers


 

Economic Benefits


Improving the power factor can significantly reduce electrical losses and operational costs, making the system more efficient and cost-effective.

Transformer operation and maintenance
Transformer operation and maintenance
Transformer Operating TemperatureDuring operation, transformers generate copper losses and iron losses, both of which are converted into heat, causing the transformer’s temperature to rise. Most transformers in China use Class A insulation. Due to heat transfer characteristics, significant temperature differences exist between different components during operation: winding temperature is the highest, followed by the core, and then the temperature of the insulating oil (with upper-layer oil being

What is Voltage Stability in Power Systems?
Definition of Voltage StabilityVoltage stability in a power system is defined as the ability to maintain acceptable voltages at all buses under both normal operating conditions and after being subjected to a disturbance. In normal operation, the system’s voltages remain stable; however, when a fault or disturbance occurs, voltage instability may arise, leading to a progressive and uncontrollable voltage decline. Voltage stability is sometimes referred to as "load stability."Voltage instability c

What is Dual Trace Oscilloscope?DefinitionA dual-trace oscilloscope uses a single electron beam to generate two separate traces, each deflected by an independent input source. To produce these two traces, it primarily employs two operating modes—alternate mode and chopped mode—controlled by a switch.Purpose of a Dual-Trace OscilloscopeWhen analyzing or studying multiple electronic circuits, comparing their voltage characteristics is often critical. While one could use multiple oscilloscopes for

What is Cathode Ray Oscilloscope (CRO)?
What is Cathode Ray Oscilloscope (CRO)?DefinitionA cathode ray oscilloscope (CRO) is an electrical instrument for measuring, analyzing and visualizing waveforms and other electronic/electrical phenomena. As a high - speed X - Y plotter, it shows an input signal against another signal or time. Capable of analyzing waveforms, transient phenomena and time - varying quantities across a wide frequency range (from very low to radio frequencies), it mainly operates on voltage. Other physical quantities
