7% Dry Type Iron Core Reactor
When operating a frequency converter, it is possible that the mains voltage waveform may be distorted in the form of harmonics with a frequency of 250 Hz, 350 Hz, 550 Hz, etc.
The presence of harmonics leads to emergency operation of consumer electrical installations. The use of network chokes makes it possible to eliminate such modes.
In addition, the mains choke is an element of protecting the frequency converter from voltage surges in the supply network, as it reduces the rate of current rise and allows you to protect the electrical installation without its failure.
The use of network chokes in combination with a frequency converter makes it possible to increase the reliability of operation and obtain a significant economic effect, since the service life increases dramatically.
