Flexible current coil, also known as a Rogowski coil, is useful for testing objects, on which hard clamps cannot be attached. The HD version (Heavy Duty) features increased resistance to mechanical damage. In the measurements of alternating current, flexible coils are connected directly to the meter.

With the 5-pin termination, they are connected directly to the instrument. The rated current of this product is 3000 A and the diameter of the enclosed conductor is maximum 145 mm.
