Rogowski Coil - Advantages

Advantages

This type of coil has advantages over other types of current transformers.

  • It is not a closed loop, because the second terminal is passed back through the center of the toroid core (commonly a plastic or rubber tube) and connected along the first terminal. This allows the coil to be open-ended and flexible, allowing it to be wrapped around a live conductor without disturbing it.
  • It has an air core rather than an iron core, it has a low inductance and can respond to fast-changing currents.
  • Because it has no iron core to saturate, it is highly linear even when subjected to large currents, such as those used in electric power transmission, welding, or pulsed power applications.
  • A correctly formed Rogowski coil, with equally spaced windings, is largely immune to electromagnetic interference.

Famous quotes containing the word advantages:

    To say that a man is your Friend, means commonly no more than this, that he is not your enemy. Most contemplate only what would be the accidental and trifling advantages of Friendship, as that the Friend can assist in time of need by his substance, or his influence, or his counsel.... Even the utmost goodwill and harmony and practical kindness are not sufficient for Friendship, for Friends do not live in harmony merely, as some say, but in melody.
    Henry David Thoreau (1817–1862)

    But there are advantages to being elected President. The day after I was elected, I had my high school grades classified Top Secret.
    Ronald Reagan (b. 1911)

    We work harder than ever, and I cannot see the advantages in cooperative living.
    Lydia Arnold, U.S. commune supervisor (of the North American Phalanx, Red Bank, New Jersey, 1843- 1855)
