Neutral Grounding Reactors are single phase units, and are installed at specific locations in the transmission network, particularly at the neutral of large power transformers. They are used to limit the line to ground fault current under system earth fault conditions to specified levels.
Neutral Grounding Reactors are widely preferred over other resistors mainly because of much lower losses arising from the unbalance currents. It is widely accepted practice for improving the transient stability in EHV transmission systems where single pole reclosing is needed.
Neutral Grounding Reactors interrupt secondary arc currents produced by capacitive and inductive coupling with the two energized phases of the same circuit or with the parallel circuit in case of double circuit lines. And it can be installed along with the already available line connected shunt reactors to reduce the magnitude of secondary arc current.
While the rector is suitable for both indoor and outdoor use, there are some important things, and before you start looking for some top neutral grounding reactors, you should know them.
The temperature of the place where the reactor is installed should not exceed 50 °C and it should not be less than 40 °C. You should keep the temperature according to your needs. And the reactor is capable of working within that temperature range, which is ambience temperature.
The reactor position should not go beyond three thousand meters. You can install it at any height below that limit. You should keep this in mind when you are looking for neutral grounding reactors for a power networking system.
Maximum wind speed
Wind can affect the functioning of your neutral grounding reactors. So make sure the place it is to be installed at does not receive wind blowing at more than 45m/s.
It is one of the crucial factors that impact the performance of neutral grounding reactor. If there is more than 90% humidity at the place, this may cause the reactor to develop some problems. Or it (reactor) may not work as efficiently as it should.
The seismic capacity of neutral grounding reactors will vary. This may be anything between 0.30g horizontal and 0.15g vertical
In addition, installation location should also be clean. There should be no harmful gas, stream, electric conductivity, or explosive dust. They may adversely affect the performance of the reactor. So you should make sure the place where the reactor is to be installed is extremely perfect. Once everything is fine, you should buy high quality neutral grounding reactor here at TEEE, which has carved a niche by offering high performance transmission, electric, and energy equipment at the most competitive price in the USA.
