Power Quality Analyzers, often referred to as Power Analyzers, make a digital recording of the voltage and current waveform (typically either one phase or three phase) and accurately calculate true power (watts), apparent power (VA) power factor, AC voltage, AC current, DC voltage, DC current, frequency, IEC61000-3-2/3-12 Harmonic measurement ...
In Electrical Engineering, a static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks.
APFC may refer to: Active/automatic power factor correction/control (panel), used to control the power factor of electrical loads; Alaska Permanent Fund Corporation; Albert Park Football Club, a present-day amateur Australian rules football club; Albert Park Football Club (VFA), a former Australian rules football club from the 1860s and 1870s
The Alaska Permanent Fund (APF) is a constitutionally established permanent fund managed by a state-owned corporation, the Alaska Permanent Fund Corporation (APFC). [1] It was established in Alaska in 1976 [2] by Article 9, Section 15 of the Alaska State Constitution [3] under Governor Jay Hammond and Attorney General Avrum Gross. From February ...
An important property of three-phase power is that the instantaneous power available to a resistive load, = =, is constant at all times.Indeed, let = = To simplify the mathematics, we define a nondimensionalized power for intermediate calculations, =
In telecommunications, the free-space path loss (FSPL) (also known as free-space loss, FSL) is the attenuation of radio energy between the feedpoints of two antennas that results from the combination of the receiving antenna's capture area plus the obstacle-free, line-of-sight (LoS) path through free space (usually air). [1]
You can use an online calculator to figure the present and future value of an annuity. ... The formula for calculating the present value of an ordinary annuity is: PV = C x [(1 – (1 + i)^-n) / i]
In the power systems analysis field of electrical engineering, a per-unit system is the expression of system quantities as fractions of a defined base unit quantity. . Calculations are simplified because quantities expressed as per-unit do not change when they are referred from one side of a transformer to t
