The C series contains powerful clamp transformer for 1000 A. The round shape of the jaws and the uniform winding of the coil guarantee a high accuracy and minimum phase shift.The optimum adjustment of the magnetic circuit through a pendulum-joint system and a patented support system for the progressive opening of the jaw plates facilitate the operation.The 52mm diameter of the wrap allows CAT III 600V measurements to be made on most industrial and office building conductors.Due to the low phase shift and the high linearity, this clamp transformer equipped with a core made of µ-metal is excellently suitable for power measurements.This text is machine translated.
