Simple electrical sources include inductive loads such as relays, solenoids, and the brush contacts in electric motors.
12.
Capacitive loads are leading ( current leads voltage ), and inductive loads are lagging ( current lags voltage ).
13.
Real transmission lines typically serve inductive loads, which are the motors that exist everywhere in modern electronics and machines.
14.
That is to say, for each 100 kW of resistive load, 75 kVAr of inductive load is provided.
15.
This happens because in an inductive load, it is the induced electromotive force that causes the current to flow.
16.
By convention, a " lagging " or inductive load, such as a motor, will have positive reactive power.
17.
Body diodes may be utilized as freewheeling diodes for inductive loads in configurations such as H-bridge or half bridge.
18.
Inductive loads such as transformers and motors ( any type of wound coil ) consume reactive power with current waveform lagging the voltage.
19.
Typical application of this technique in an inductive load chopper circuit showed a significant reduction in the tail current of freewheeling diode used.
20.
The main commercial benefit when installing VO units, is on inductive loads, like motors which run pumps, fans and the like.
