What is Rogowski's coil?
and Rogowski Coil is a simple device used to measure alternating current or high -speed electric currents. Its unique design distinguishes it from other measuring devices structurally and powerful. These coils are used in many fields and are sought for the accuracy they provide. Recently, Rogowski Coils received a lot of competition from simpler sensors using similar technology.
The design of Rogowski coil is unique because of its air core, unlike previous measuring devices that used the iron core. The core of the air comes to the kind permission that one conductor is skidding several times until it creates a tight coil, looked similar to a miniature ended garden hose. This coil is then created into a circular shape that is wrapped around the conductor that requires its current measured. The design of this coil is also unique because the ends of the wire or terminals are on the same side and create a complete loop around the conductor.
The winding of the Thacl wire E Rogowski is the most important element of the whole device. The coil loops must be evenly distributed, or they will risk lifting the magnetic interference. The more interference enters the sphere of the coil, the less accurate the measurement will be.
and Rogowski Coil measures the AC electrical current by connecting each of the wires to the integrating circuit. The target lifts the output current coming from the conductor and sends the data back to the integrator. The result is a map of current patterns and, if properly calibrated, measurement of the amount of current.
rogowski coils are used in many industries to measure currents. Electric transmission and welding, where powerful currents are often used, are the two most popular use of the coil. His ability to fit through an active conductor, because of his light construction, allows you to be used on virtually any conductor.
rogowski coil recorded a largeCompetition in the field of alternating current measurement. Newer components are able to accurately measure the current of the wire by low -cost technology of circuit and electronic sensors. These cheaper and lighter measuring equipment threatened decades of dominance of coil in the field of current measurement.
