Blondel's Theorem tells us that, to measure the total power of a three-phase load (balanced or unbalanced), we can use one less wattmeter than there are conductors supplying that load.So the two-wattmeter method will work for anythree-phase load, provided there are only threeconductors supplying that load, e.g. three-wire delta or three-wire star (wye).Bear in mind that wattmeter's read true power (expressed in watts) and ignores the reactive power of inductors and capacitors.
You measure the capacitance of a capacitor in an active circuit by observing the voltage across it and the current through it. That gives you, by Ohm's law, the impedance of the capacitor. Plug that in the the equation for capacitive reactance, and you get capacitance. Note: There is no such thing as a three phase capacitor. A capacitor is a two terminal device that resists a change in voltage inversely proportional to its capacitance. You connect one capacitor to one phase. If you have a "three phase capacitor", then you are talking about three capacitors. Deal with each one separately.
A capacitance meter is a piece of electronic test equipment used to measure capacitors. Depending on the sophistication of the meter, it may simply display the capacitance or it may also measure a number of other parameters such as leakage, equivalent series resistance, and inductance.
most capacitors will measure infinite resistancestarting capacitors are used to set up a rotating magnetic field by phase shifting a coil in a single phase motorwhen the motor gets up to speed a centrifugal switch will disconnect the capacitorthis happens at a random time and can leave the capacitor with a charge easily 4x the applied ac voltage (+/-1,000V)so some capacitors rated as starting capacitors will have an internal bleeding resistorGas discharge lamp ballast capacitors sometimes have discharge resistors.Microwave ovens have capacitors usually in a voltage doubling configuration(+/-20,000V) most have an internal bleeding resistor.Never rely on this resistor being intact or even present.It can have fatal consequences.the internal resistors are sized to discharge the capacitors in tens of minutesTc = R * C ( seconds = ohms * farads )
Joules measure energy (power x time). If the AC voltage is expressed as rms (root mean square) and not peak, and there are no capacitors or inductors in the circuit, then the joules per second (=power ) will be the same.
Impedance, resistance, and reactance.
The unit of measurement for inductive reactance (XL) is the ohm.
If its capacitors you are talking about, it stands for nanoFarad and it is a unit of measure.
Capacitors are measured in Farads or microfarads.

While it is true that an inductor opposes the flow of an alternating current, it does not necessarily 'block it'. The quantity that opposes the flow of an AC current is the inductor's inductive reactance, expressed in ohms. Inductive reactance is proportional to the frequency of the supply voltage and, at 50 or 60 Hz, the reactance of a transformer's winding is relatively low (although very much higher than its resistance) and, while this acts to limit the amount of current flow, it certainly doesn't act to block that flow.
The electrical abbreviation ( UH ) is a measure of inductance , as in a ferrite transformer core , inductors , choke etc. .
Latitude and longitude are angles, and can be expressed in any unit of angle measure. Degrees are quite popular.
The measure of the steepness of line expressed as rise over run is called slope.
Mass is not expressed in kilometers (km). That is a measure of distance. Mass is expressed in units of kilograms (kg)
This measure is called concentration, expressed in g/L.
