DESCRIPTION : The OMICRON
CT Analyzer is a compact, highly accurate test system for testing, calibration and assessment of conventional
current transformers (CTs).The instrument injects low test signals into the CT secondary, determines the CT
equivalent-circuit parameters and automatically evaluates the CT according to the selected standard.

Key measurements and functions:
– CT ratio and phase accuracy
– Winding resistance
– Excitation characteristics and knee-point voltage
– Burden impedance
– Composite error and protection parameters
– Transient CT classes and parameters
– Remanence and residual magnetism
– Automatic determination of unknown CT nameplate parameters
– Automatic demagnetization after testing
– Immediate good/bad assessment

Key benefits:
– Automatic test duration of less than one minute
– High measurement accuracy, including 0.02% class calibration capability
– Lightweight design under 8 kg for field use
– Tests performed at a maximum of 120 V for improved workplace safety
– Automatic evaluation according to IEC, IEEE and supported customized or local standards

The CT Analyzer is suitable for commissioning, maintenance, troubleshooting and calibration of protection and
metering CTs.
