Model 5500A/COIL
50-Turn Current Coil
Introduction
The 5500A/COIL is a 50-Turn Current Coil 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). It is impractical to calibrate 1000A rated current clamp meters using a 1000A source. How-
ever, by using the 50 turns of the 5500A/COIL in conjunction with a current source calibrator one can ef-
