1 Introducing the A1582
The A1582 Flexible Current Clamps consist of the flexible sensor and an
electronic module on the connected wire. It has three current ranges 30A, 300A and
3000A. The current range of the A1582 is selected directly by the connected instrument.
The electronic module is powered from the connected instrument to. The flexible sensor
permits measurements on conductors where standard clamp-on current transformers
can not be used. It is particularly useful for installation in tight spaces, or around breaker
panels, cable bundles, wide or large bus bars and irregular shapes. Unlike standard
current transformers, this flexible CP does not use magnetic cores. The transformation
principle is based on an air core. It presents virtually no load to the system under test,
has a low phase shift and excellent frequency response.
A1582 Flexible Current Clamps have silicone cover, and therefore are particularly
suitable for measuring on substations busbars where temperature can reach more than
105 °C temporary. Additionally, A1582 cannot be damaged by overloads. The A1582
Flexible Current Clamps are insensitive to DC current and measure only the AC
component of the measured signal.
