Reactor vs resistor
WebMay 3, 2024 · In an AC circuit, reactance is the opposition to current flow. A reactor, also known as a line reactor, is a coil wired in series between two points in a power system to minimize inrush current, voltage notching effects, and voltage spikes. Reactors may be tapped so that the voltage across them can be changed to compensate for a change in … WebFeb 24, 2012 · Series Reactors are connected to the system in series. They are normally used to limit the fault current in the system or to facilitate proper load sharing in a parallel power network. When a series reactor is …

WebApr 1, 2024 · The following has to be true: - The voltage across the resistor (red arrow) and the voltage across the inductor (blue arrow) have to spatially add-up to equal the supply voltage (black arrow). That addition is shown by the dotted lines. WebMay 1, 2024 · Resistive heating is the process by which an electric current passes through a conductive material (the resistor) and releases heat. The greater the resistance the electricity encounters, the more heat is created. This can be measured as a value of "electrical resistance", and its inverse property is measured as "electrical conductance."
Webreactors are prone to magnetic saturation at high current levels, this limitation can be mitigated by the use of air cored reactors. Air core reactors show a linear characteristics … WebJan 15, 2013 · This would be unusual in your situation but may influence the choice of a reactor over a resistor.
