What is inductive load device?

Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.

Which machine is used for power factor correction?

Power factor correction equipment including static contactors (thyristors) instead of usual contactors is particularly suitable for a certain number of installations using equipment with fast cycle and/or sensitive to transient surges.

What is the power factor of inductive load?

For the purely inductive circuit, the power factor is zero, because true power equals zero.

How does inductive load affect power factor?

Reactive power required by inductive loads increases the amounts of apparent power – and the required supply to the grid from the power supplier to the distribution system. Increased reactive and apparent power will decrease the power factor – PF.

Is a relay an inductive load?

For example, our digital outputs and alarm relays commonly drive inductive loads that include motor windings, solenoids, interposing relay coils, physical inductors, and even the load wiring itself. In all cases, we routinely recommend that protection be placed local to the inductive load being switched.

How is inductive load measured?

The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. XL =2p x f x L. L = the inductance value of the coil in henries.

What are different methods of power factor correction?

According to the location modalities of the capacitors, the main methods of power factor correction are:

  • Distributed power factor correction.
  • Group power factor correction.
  • Centralized power factor correction.
  • Combined power factor correction.
  • Automatic power factor correction.

What kind of power factor is available in case of inductive load?

But for inductive load, the load consumes reactive power, hence reactive component will be positive. The value of leading power factor i.e., with capacitive load ranges between -1 to 0. While for the lagging power factor i.e., with an inductive load, it lies between 0 and 1.

How do you calculate inductive load?

Why do inductive loads cause lagging power factor?

The main cause of lagging power factor is using Pure Inductive(L) Load or Resistive-Inductive(R-L) Load. When a pure inductive load(which has no resistance) is connected with AC supply then no active or real power is consumed only reactive power flowing in the circuit and the power factor will be Zero lagging.

Are solenoids inductive loads?

An inductive load is any device which has coils of wire, which when energized, generally perform some kind of mechanical work, for example solenoids, motors, and actuators.
