Calibration test system KFS series

high-voltage

Sphere Gaps (Horizontal & Vertical) for Impulse, AC or DC Voltage Calibration The KFS sphere gaps can be used for Impulse, AC or DC voltage calibration according to the IEC 60052 recommendation. It can also be used for chopping of lightning impulses. General Description The sphere gaps can be used for Impulse, AC or DC voltage calibration according to the IEC 60052 recommendation. The sphere-gap presents the undeniable advantage of a direct and straightforward voltage measurement, where only the sphere diameter and their distance give a voltage measurement within ± 3 % accuracy. As both spheres are mounted on columns of insulating material in the horizontal sphere gaps, it’s possible to superimpose impulse, alternating and direct voltages for special tests. For the chopping of lightning impulses, the sphere gap can be equipped with the optional chopping device KFS Z. The type designation consists of the characters KFS, H for horizontal design and V for vertical and the sphere diameter in mm, e.g. KFS H 250.
