WORKING PRINCIPLE

 An air-cored toroidal winding is placed around the conductor, themagnetic field produced by the current induces in the coil a voltage

proportional to the rate of change of current.

Integrating this voltage the output become proportional to the current

(as for a current transformer).

ROGOWSKI COIL ADVANTAGES

0uitable to measure from few Amps to hundreds of 1Amps

2ery useful with large si3e or aw1ward shaped conductors or in

places with limited access

No danger for installation around current-carrying conductors

Non-intrusive, no power drawn from the circuit under test

2ery high linearity

4ight enough even to be suspended on the measured conductor
