what is the difference between real reactive and apparent power?

Reactive power does not do any work, so it is represented as the imaginary axis of the vector diagram. Active power does do work, so it is the real axis. The unit for power is the watt (symbol: W). Apparent power is often expressed in volt-amperes (VA) since it is the product of rms voltage and rms current.

Watts is the real power drawn by the equipment, while volt-amps are called the “apparent power” and are the product of the voltage applied to the equipment times the current drawn by the equipment.

The rate of doing work is called power. The basic difference between average and instantaneous power is that average power is the ratio of total work and total time. While instantaneous power is the limiting value of average power.

1. DC power is significantly more energy efficient than AC power. DC motors and appliances have higher efficiency and power to size characteristics. DC-based lighting (LED) is as much as 75% more efficient than incandescent lighting.

The power factor measured at the Utility meter increases to 80 kW / 85 kVA> X 100 = 94%. The relation between the real power (kW), the apparent power (kVA) and the reactive power (kVAR) may be represented by a triangle as follows: With respect to “inductive loads”, a load that uses magnetic fields.

Nominal Power is your average power consumed. Rated Power is usually the maximum power that the device may consume. An example is the rating on a motor. When the motor is running at normal loading, that is the nominal power rating.

In a nutshell, active components can, generally speaking, inject power into a circuit and are capable of electrically controlling and amplifying the flow of electrical current, whereas passive components cannot. Unlike active components, passive components either consume or store energy.

If the load power factor is unity then output power will be maximised and the efficiency will be maximum. If the load power factor is less than unity, the true or real output power will correspondingly reduce as will the efficiency.

An absolute truth is that there is no human soul not worthy of salvation. A realative truth is that if you don't pay your electric bill your power will get shut off. Lol realative is subject to you and your particular environment or culture or societal norm.

At resonance the voltage across the inductance and the capacitance will be 90 degrees out of phase with the current but in opposite directions. So the current will be in phase with the applied voltage and the voltages across the reactive components could be quite large. There are two basic circuits.

The main difference between 0-10V and 1-10V is the direction of the current between dimmer and driver. 0-10V is a current source system, which means that the dimmer provides the power for the 0-10V signals – a mains connection to the dimmer is necessary.

Here's a breakdown of these two loads: Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. ... Capacitive reactance resists the change to voltage, causing the circuit current to lead voltage.

Answer: The ideal voltage source has a constant voltage across its terminal, irrespective of the current drawn from the source. ... While the practical voltage source can supply only limited amount of current to the load. Also, practical voltage source has series internal resistance.

Power factor is the ratio of the real power to the apparent power. ... The displacement power factor is based purely on the fundamental line frequency (50 or 60 Hz) content, while the apparent power factor includes harmonics in the computation. All series WNB and WNC WattNode® models measure the displacement power factor.

Moreover, in power plant, power factor is 1 therefore MW is equal to MVA …… (MW = MVA x P.f).

MVA is the apparant power, MW is the real power and, MVAR is reactive power. MW describes the actual power that can be supplied to the load and MVA includes both the power supplied to the load AND the power that recirculates between the power plant and the load (volts*amps).
