Page 6: Typical Applications
Flex current clamps A 1501, A 1502 and A 1503 5 Typical applications 5.1 Power Quality Measurement Current clamps have linear response through wide frequency bandwidth (see Figure 7 and Figure 11). Therefore they are well suited for: Power Quality auditing, ... - Page 7 Flex current clamps A 1501, A 1502 and A 1503 It is very important that the conductor is in the centre and perpendicular to the current censor as much as possible, in order to minimise position measurement error. Minimise influence of adjacent current-carrying conductors, and measure at the point where they are far away from each other.
