The COSI-MU integrates a set of analog voltages together with the full COSI product range, which includes COSI-CT, COSI-CM and COSI-CT F3.
COSI-CT
The COSI-CT design permits current measurements to be made with extended range accuracy.
To address stringent revenue metering applications, its performance exceeds
IEC 0.2S / IEEE 0.3 / IEEE 0.15S Classes with a dynamic range that extends from 1 A to 4800 A.
To address protection applications, its performance exceeds IEC5P / IEEE 10% / TPY protection: 63 kArms for 1s.
COSI-CM
The COSI-CM combines analog voltage transformers with wide dynamic range optical current transformers to make a compact metering and protection system. The optical CT has the same specifications as the COSI-CT. Capacitive voltage transformers (CVTs) are used in high-voltage and extra high-voltage transmission systems to provide potential outputs to metering instruments and to protective relays.
COSI-CT F3
The Alstom Grid COSI-CT F3 optical current sensor is the most flexible, portable optical current transformer sensor available and the easiest to install.
