How do inductive loads work

Capacitive reactance resists the change to voltage, causing the circuit current to lead voltage. A capacitive load bank is similar to an inductive load bank in rating and purpose.

However, lightly loaded switched mode power supplies applied to reduce harmonic currents and long cable runs cause a system draw, a leading power factor, allowing reactive power to be supplied from these loads to the system.

As a result, power factor improves. More resources. Achieve Solar System Testing, without the Grid. Read more. Contact a power testing equipment expert today Do you have a question?

Select one The current becomes Lagging from the Voltage Wave. Capacitive loads causes the Voltage rate to be blocked, resulting in a shift in the position of the current wave leading to the voltage wave, Electrical devices that including type of Capacitive Loads is Capacitors Condensers.

Unknown November 1, at PM. So that includes, light bulbs, computers, refrigerator, etc all these consumes electric power and hence we can refer them as electrical load. Now, if we look at the nature of such load, we can actually categories them in three different types. And those are. Load which consumes only active power is called as resistive load.

Now when I say they are perfectly in phase, that means, both the waveforms reaches their peak value at the same time. They also reaches the zero value at the same time. One example is shown above. As such type of load only consumes active power, power flows from Source to load only.

There will be no power flowing from Load to source. As such loads only consumes active power, power factor of such loads is Unity! And which is a very good sign. If you want to know power factor in detail you can go through my complete playlist on Power Factor. Load which consumes only reactive power is called as inductive load. Now, when I say they out of phase, that means, both the waveforms reaches their peak value at different times. They also reaches the zero value at different times. Load banks create power demand using resistive, inductive, and capacitive elements.

This brief summarizes their differences. Overview In an alternating current system, current occurs in sine waves according to the frequency of the power source.

In a circuit unaffected by inductance or reactance, voltage and current would rise and fall together during each cycle. This condition, known as unity , is shown in Figure 1. In practice, circuits present inductive or reactive characteristics that cause voltage and current to peak at separate times in an ac cycle. In inductive circuits, voltage leads current, as shown in Figure 2.

In capacitive circuits, voltage lags current, as shown in Figure 3. Greater amounts of time between current and voltage peaks indicate a greater amount of inductive or capacitive load, and either condition increases the work needed to deliver the required amount of real power to loads. The extent to which the voltage and current peak at separate times is quantified by the power factor. For purely resistive loads, power factor equals 1.
