A low power factor due to inductive loads ( usually due to motors such as air conditioning ) causes extra expense to the utility, since they have to have oversized conductors and transformers.
32.
Usually the source terminal of the N-MOSFET is connected to the cathode of a recirculation diode allowing for efficient management of stored energy in the typically inductive load ( See Flyback diode ).
33.
Typically, the inductive load will be rated at a numeric value 75 % that of the corresponding resistive load such that when applied together a resultant 0.8 power factor load is provided.
34.
As Edison noted, lowering the voltage reduces the amount of electricity delivered to resistive loads; lowering the frequency similarly reduces the amount delivered to inductive loads, i . e . electric motors.
35.
It is the slide type, and they do call it a dimmer, but don't give the disclaimer that it's just for resistive loads, not inductive loads, as another model did.
36.
The commutating d " v " / d " t " is very important when the TRIAC is used to drive a load with a phase shift between current and voltage, such as an inductive load.
37.
A lagging power factor signifies that the load is inductive, as the load will consume reactive power, and therefore the reactive component Q is positive as reactive power travels through the circuit and is consumed by the inductive load.
38.
They are normally designed to provide very high current output compared to a purely electronic UPS, and are better able to provide inrush current for inductive loads such as motor startup or compressor loads, as well as medical MRI and cath lab equipment.
39.
Consequently, for relays used to control inductive loads, we must specify the maximum current that may flow through the relay contacts when it actuates, the " make rating "; the continuous rating; and the " break rating ".
40.
:: : : In this picture current is flowing across the wireless gap between the rail and the pickup shoe and supplying uninterrupted power to the inductive load of the motor . " Distance " is a relative, not absolute, concept . talk ) 15 : 28, 9 July 2012 ( UTC)
