Re: Reactor in Substation

Isn't that a synonym for "capacitor," as in a capacitor bank for power factor correction?
 
Re: Reactor in Substation

In a nutshell, it's a choke.

A reactor is an inductive impedance deliberately added for specific affect.

What's the one you are thinking of connected to?

Power line reactors add inductance to lightly loaded HV power lines that are quite capacitive by design. Under little or no load, an HV line, 115KV and above, will sometimes see an increase in the receiving end voltage instead of seeing a drop in voltage over the line. This often happens under lightly loaded conditions, and the reactor will tend to negate the voltage rise.

Also sometimes there are small reactors in individual phases used to block relay communications signals from travelling thru substations and interfering with other signals as well.

Hope that helps

Hey. I had it right, except for the small detail of having it backwards. :D
 
Re: Reactor in Substation

In industrial substations and sometimes in older utility substations, reactors are used to reduce the short circuit current. Adding a reactor is cheaper than replacing equipment if the available short circuit current gets too high.
 
Re: Reactor in Substation

thanks... the reactors actually interconnect different feeders in my drawings. I can definitely picture the reactors(inductances) slowing down a massive current surge (fault).

Your punishment is to draw 100 exponetial growth curves on the chalkboard. :D
