Type L Choke Coil, 200 Ampere Capacity End View of For 13,200 Volt Circuit Same Coil When a lightning disturbance travels along a line, it usually has a verysteep wave front. This incoming wave striking the highly inductive windingsof a transformer or other piece of electrical apparatus dams up and frequentlybreaks down the insulation of the first few turns of wire, causing a burn-outand throwing the apparatus out of service. This phenomenon is based on the well-known fact that a turn or coil ofcopper wire offers a high inductive resistance to the passage of high frequencyalternating currents. This inductive resistance is affected very slightly by theresistance of the wire, but depends almost entirely on the inductance of the coiland on the frequency of the discharge flowing through it. The use of choke coils is based on thi> phenomenon and it is to knock-off the crests of these incoming waves that they are used. If we take a coil of heavy copper wire, connect it between a generato
