Web27 nov. 2024 · Answer: The way the delta is ‘closed’ determines which side leads or lags. There are two possible combinations which are discussed below: Delta Closing- Type DAB This is one method of closing the delta triangle. In this connection, the polarity side of A phase is connected to the non-polarity side of B phase. WebA power factor closer to 1 provides the maximum utilization of power drawn from the grid. A low power factor indicates inductive or capacitive elements in the circuit causing the current drawn to lag or lead the voltage, respectively, decreasing the instantaneous real power available to the load and consuming unnecessary current capacity on the cables.

Web15 aug. 2024 · The real power is along the horizontal axis, the reactive power is along the vertical axis, and the apparent power forms the hypotenuse of the triangle as shown in Figure 2. Figure 2. Power triangle. Using geometry, S can be calculated by: The cosine of angle θ is defined as the power factor (pf). The power factor is the ratio of the real ... Leading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In this type of circuit, the terms lead, lag, and in phase are used to describe current with reference to voltage. Current is in phase with voltage when there is no phase shift between the sinusoids describing their time varying beh… WebAs it is discussed the phase of a wave either lags or leads with that of another wave, leading corresponds that a wave is at the forefront of the other having the same amount of frequency. Whereas lagging corresponds that a wave is at the back of the other wave with the having amount of frequency. paisa bazaar cibil score company
