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
). Therefore they are well suited for:
Power Quality auditing,
EN 50160 or troubleshooting. Particularly for:
Current distortion measurement
Inrush measurement
Functional testing of appliances, machines, etc.
High precision (see Figure 5 and
) and wide measurement range can cover most of
practical LV current measurements.
5.2 Energy and Power Measurement
Current clamps have small phase shift (see Figure 8 and
) over wide frequency range.
Therefore they are well suited for:
Power and energy measurements (active, reactive, apparent)
Power factor measurements
Power/Energy efficiency
6 Connecting and using clamps in the field
1. Wrap the flexible measuring head around the conductor to be tested and close
coupling
