Any devices or equipment that have coils in them are inductive in nature. Examples of inductive load are motors, solenoids, contactor coils, compressors, speakers, relays, transformers, inductors, power generators, etc.
Is a motor a resistive or inductive load?
As you might guess from the name, resistive loads only resist the current and are the simplest type of load. In inductive loads, such as an electric motor, the voltage wave is ahead of the current wave.
Is refrigerator an inductive load?
Loads that power electrical motors are inductive loads. These are found in a variety of household items and devices with moving parts, including fans, vacuum cleaners, dishwashers, washing machines and the compressors in refrigerators and air conditioners.
What is a non inductive load?
The load is connected to an electric circuit and it consumes electric energy. Loads are divided into inductive loads and non-inductive loads. An inductive load contains a coil, such as a motor. Non-inductive loads are divided into lamp loads and resistive loads.
Is a solenoid an inductive load?
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.
What is inductive load example?
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.
Are LED lights inductive or resistive load?
“When migrating from incandescent bulbs to either CFLs or LED lighting, the load isn’t resistive anymore, it’s inductive or capacitive so the dimmer doesn’t behave the same way as it would with an incandescent bulb.” “The result is flickering when the dimmer interacts with the input of the LED drivers,” Anumula added.
How do you know if a load is inductive or capacitive?
If both inductors and capacitors are present then simply find the equivalent impedance of the load network. If the imaginary part of the equivalent impedance is positive then the load is inductive, if it is negative then it is capacitive, and if it is zero then it is resistive.
Are LED lights inductive loads?
LEDs are a nonlinear load and probably these lamps will not have a power factor correction converter. This means that the current will not be sinusoidal therefore you will have some reactive power flowing. There may be a PFC choke before the rectifier bridge.
What are examples of resistive loads?
Two common examples of resistive loads are incandescent lamps and electric heaters. Resistive loads consume electrical power in such a manner that the current wave remains in phase with the voltage wave. That means, power factor for a resistive load is unity.
How do you calculate inductive load?
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.
What is the difference between inductive and non inductive resistors?
A non-inductive resistor is wound one way then again in the other direction, as shown below. … A non-inductive resistor can be used to replace an inductive resistor, but that might not be a realistic goal. Inductive resistors are typically cheaper to construct and are more commonly made with higher power ratings.
Is a microwave an inductive load?
By convention, a “lagging” or inductive load, such as a motor, … A “leading”, or capacitive load, such as a microwave oven, has negative reactive power.
What type of load is a solenoid?
Examples of devices that behave as inductive loads: Solenoids / electromagnetic valves. Electromagnets.
How can inductive load be reduced?
Inductive loads of fluorescent ballasts.
A few of these strategies are:
- Install capacitors in the distribution system.
- Minimize operation of idling or lightly loaded motors.
- Install variable frequency drive (VFD) systems to lightly loaded induction motors.
- Install new motors that will be operated near their rated capacity.
How do you protect inductive loads?
The most commonly used contact protection devices for inductive loads are Varistors and RC networks. These protection devices are always connected in parallel to the inductive load. For best results, locate the protection device as close as possible to the inductive load.
