· Many appliions of this type of circuit depend on the amount of circulating current as well as the resonant frequency, so you need to be aware of this factor. In fact, in realworld circuits that cannot avoid having some resistance (especially in L), it is possible to have such a high circulating current that the energy lost in R (p = i²R) is sufficient to cause L to .

In this chapter, we call a circulatingreflux stream a pumparound. The vast majority of fractionators have top reflux. Cold liquid from the reflux drum is pumped onto the top tray of the tower. The cold liquid flashes to a hotter vapor. For example, let s say 1500 lb/h of liquid butane at 100 F flashes to 1500 lb/h of vapor at 260 F.

Calculating the Pump Head Before we can discuss pump head, we must understand the difference between an open hydronic system and a closed hydronic system. It is important to know whether the pump serves an open or a closed system, because the pump head calculation depends on the type of system that the pump serves. In a closed system, the fluid is not .

Active or real or true power that do the actual work in the circuit can be calculated as. P = Urms Irms cos φ (12) where. P = active real power (W) φ = the phase angle between the current and the voltage (rad, degrees) Cos φ is also called the Power Factor. Reactive power in the circuit can be calculated as.

· Volts x Amps = Watts. Amps = Watts/Volts. These formulas can be used to calculate the capacity and loads of individual circuits, as well as for the entire electrical service. For example, a 20amp, 120volt branch circuit has a total capacity of 2,400 watts (20 amps x 120 volts). Since the standard recommendation is for the load to total no ...

When two transformers are in a parallel group, a transformer with a higher tap position will typically have a higher (LV side) noload voltage than the other one with a lower tap position. These unequal noload voltages (unequal tap positions) will cause a circulating current to flow through the parallel connected transformers.

Paralleling by the circulating current method makes use of the fact that it is desirable that the transformers share the load equally and, therefore, any difference of current in the paralleled transformers is to be minimized. Special circuits have been developed to "break out" the unbalanced current from the total transformer current and

Knowing this tiny bit of information helps you to know how much power you can draw without tripping your circuit breaker. With that in mind, here's how to calculate lighting load: Obtain your electrical circuit's amperage from your circuit box. Multiple your amperage by your voltage limits. Once you have your power load, subtract all other loads from that to know how much .

· If we think of a 3 phase load producing tripling harmonics (current sources in parallel with load, injecting harmonic currents into the system). (I've read that harmonics generated due to nonlinear loads can be thought of current harmonic sources connected in parallel to the load, so that is how I'm thinking when I'm imagining the following scenario.)

Here the current reaches zero before the voltage. Hence we can say that the current leads voltage by 90 deg. (angle as per diagram). This is called leading current. The Leading current can be called as leading Power factor. Also, the leading current can be defined as, an alternating current that reaches its maximum value up to 90 degrees ahead ...

· Circulating currents that diminish load capability and increased losses. The bus ratings could be too high. Paralleling transformers reduces the transformer impedance significantly, the parallel transformers may have very low impedance, which creates the high short circuit currents.
