This article describes in detail what a Inductive loads on electricity is and Inductive load characteristics, advantages and disadvantages.
Inductive loads are the loads that power electric motors or induction load. The list of inductive loads includes moving parts for household and industrial appliances, including Fan, Dishwasher, washing machine, Vacuum cleaner, Refrigerator, Air Conditioner and Air compressor.
Electrical loads and types;
Electrical circuits have three basic types of loads, which are classified according to their nature as resistive loads, inductive loads and capacitive loads. Each of these differs in how an alternating current (AC) uses electricity. This article will give you an in-depth look at the inductive loads mentioned above. These are compatible with mechanical loads. Some scholars and engineers refer to "linear" and "nonlinear" loads, which are difficult to understand in practical.
Inductive Load Phase Angle Relationship
Current and voltage waves travel at different phases
and at different angles under inductive load. E.g., The voltage wave crosses at
180°, and then the current wave stays
directly at an angle of 210°. The angle between
these two angles (210 - 180 = 30 degrees) is called Pi. Symbol of Pi - φ
At this load the waveform of the voltage crosses zero point first than the current (I). That is, it is called the lagging current, because delay the crossing of the current from the positive wave to the negative wave for next half cycle. Voltage (V) crossed 180 degree, Current (I) crossed 210 degree. You can see this gap between the two wave axes called pi (Symbol of pi φ) here in the inductive load wave foam image. This is also called the RL load. The following characteristics do not apply to DC voltages on inductive loads.
Difference between Resistive loads and Inductive loads
The main difference between resistive loads and inductive loads is the difference between their voltage and current waves.
Unlike resistive loads, at pure inductive loads, the current follows a sinusoidal pattern that rises after the voltage sine wave peak. Current is the wave that rises after the maximum, zero, and minimum points of the voltage sine wave are out of phase. Hence these loads are called Resistance Inductive Loads. These are commonly referred to as resistive lagging loads (RL Load). RL load means that resistance inductive load.
Inductive loads characteristic
In the wave characteristic of inductive loads, their current wave passes after the voltage. Therefore, they are electrically classified as lagging loads because the current wave passes after the voltage wave.
