Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

The traditional grid has been reliable because it is centralized. When a customer flips a switch, the lights turn on. Originally, the grid was designed with large generators accounting for much of the ...

Fundamentally, electrical power is developed, delivered, and consumed as voltage and current. In a simple direct current (DC) device such as a flashlight, the power (the brightness of the bulb) is the ...

It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

Electricity transmission network operators are being tasked with adding more renewable energy resources to the power grid. The use of static VAR compensators (SVCs) is growing as a means to control ...

Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

As gas and steam power generation plants approach the end of their operational life, plant owners face a challenging decision between upgrading or retiring the plant. Retiring a power generation unit ...
