What are the benefits of improving power factor? (Part 1)
Electricity transmission and distribution systems are designed to carry a certain amount of current without overloading. Too much current causes excessive resistive losses in electric...
Basics of reactive power compensation (Part 2)
Inductive elements, such as transformers and magnetizing coils in AC motors, store energy into their magnetic field. The direction of the magnetic field (is such...
Basics of reactive power compensation (Part 1)
Power is defined as a rate of flow of energy past a given point. In electrical circuits, power is also defined as the product of...
Basics of Harmonic Distortions (Part 2)
As the harmonic currents generated by the users’ equipment flow back towards the power source, they cause additional voltage distortion due to impedance associated with...
Basics of Harmonic Distortions (Part 1)
The load current of a purely resistive load is sinusoidal and in phase with the voltage. When the load also contains reactance, a phase-shift between...
