General Description
The
A 1398 PQA
current clamps are designed for measuring alternating currents on insulated
conductors on low power installations: 5
0 mA ÷ 20 A. They are designed for Metrel Power Quality
Instruments MI 2893 / MI 2892 / MI 2885 / MI 2884 / MI 2883.
The current transducer is housed in a plastic case that maintains double insulation. Parts are
shown on figure bellow:
1) handles,
2) safety barrier,
3) conductor opening,
4) clamps jaw,
5) cable connection with connector.

Typical applications
Power Quality Measurement
The A 1398 PQA current clamps have linear response through wide frequency bandwidth.
Therefore, they are well suited for:
– Power Quality auditing,
– EN 50160 or troubleshooting. Particularly for:
o
Current distortion measurement
o
Inrush measurement
o
Functional testing of appliances, machines, etc.
High precision and measurement range up to 20A can cover most current measurements on the
secondary side of current transformer (CT) without opening of current circuit.
Energy and Power Measurement
The A 1398 PQA current clamps have small phase shift over wide frequency range. Therefore,
they are well suited for:
– Power and energy measurements (active, reactive, apparent)
– Power factor measurements
– Power/Energy efficiency
