Reactive power is power that is reflected back to the grid - as opposed to active power, which is power that is consumed by the load.
Another way to explain this is that reactive power is the resultant power in watts of an AC circuit when the current waveform is out of phase with the waveform of the voltage, usually by 90 degrees if the load is purely reactive, and is the result of either capacitive or inductive loads....
real power is provided given the load sees a voltage & current of the same frequency that has at least some components in phase. reactive power is that power, for example in a transmission line that is 'sloshing around' but not delivering any work to your load. uncompensated inductance is ...
In AC electrical systems, phase-shifting between voltage and current introduces the concept of complex power, which has active power, reactive power, and apparent power as its components. Understanding complex power is fundamentally important for AC electrical system analysis, operation, an...
Learn what coercive power is, including its various types and examples of what it can look like in daily life. Plus, the pros and cons of using coercive power.
How does apparent power compare to true and reactive power? In an AC circuit, the product of the rms voltage and the rms current is calledapparent power. When the impedance is a pure resistance, the apparent power is the same as the true power. But when reactance exists, the apparent pow...
Figure 1 provides a conceptual overview of how real, reactive and apparent power fit together; it shows how apparent power is composed of both real power and reactive power. For most of today's circuits, the goal is to minimize the amount of reactive power in the circuit's load so it...
A comparatively small improvement in power factor can bring about a significant reduction in losses since losses are proportional to the square of the current. When the power factor is less than one the 'missing' power is known as reactive power which unfortunately is necessary to provide a ...
Reactive power is the power that is wasted and not used to do work on the load. Q=VrmsIrmssinφ Qis the reactive power in volt-ampere-reactive [VAR] Vrmsis the rms voltage = Vpeak/√2in Volts [V] Irmsis the rms current = Ipeak/√2in Amperes [A] ...
Reactive maintenance, sometimes called corrective maintenance, refers to anequipment maintenancestrategy where maintenance is only performed once an asset has broken down. The reactive maintenance approach is based on the belief that costs sustained during asset downtime or because of necessary repair are...
