Model 16201 5/10 Turn Current coil
Introduction:
The 5/10 turn 16201 Current coil is used as a tool for
calibrating clamp type current meters that operate by two different principles - as
current transformers (AC only), and by the Hall Effect (both AC and DC). As it is
typically impractical to calibrate 1000A rated current clamp meters with a 1000A source,
one can easily use 10 turns of the 16201 coil in conjunction with a 1620A current source calibrator to effectively
multiply the current of the current source calibrator by a factor of 10. Now it is
easy to support the calibration and verification of these clamp-on type current
meters.
Using the Coil:
Clamp-on current meters operate as current transformers, with varying
degrees of magnetic coupling between the primary and secondary. The position of the
clamp meter with respect to the cable also affects the magnetic coupling between the
primary and the secondary of the current transformer, which causes variation in reading of
the current meter. This is important to understand in order to make the most
accurate and repeatable measurements.
