OMICRON's CT Analyzer is a unique lightweight instrument designed to meet the highest standards for performing excitation, ratio, polarity and winding resistance tests on current transformers (CTs) as well as burden-impedance measurement.
OMICRON's CT Analyzer delivers a unique capability for the fast comprehensive testing and calibration of current transformers, for protection and metering engineers as well as CT and switchgear manufacturers.
Features and Benefits
Extremly small and lightweight (< 8kg/17 lb), beneficial for on-site testing
Reduced commissioning time due to fully automatic testing
Allows testing and result assessment according to IEC 60044-1, IEC 60044-6 or IEEE C57.13 (ANSI standard)
Accuracy level (0.02 %/1 min.) enables field calibration and verification of class 0.1 CTs for metering
Testing and automated assessment of specialized CTs such as TPS, TPX, TPY and TPZ
Allows testing of CTs for power frequencies from 16,7 to 400 Hz
Automatic analysis of CTs with unknown data ("name plate guesser" function)
Recalculation of test results after tests with different burden and different primary current (no further on-site measurements)
High level of safety - all tests utilize low voltages (120V)
European Patent EP 1 398 644 A1
Almost unlimited in: Ratio (50 000 : 1), Primary current (999 000A max.),
Knee point voltage (15kV max.)
Automatic demagnetization of the CT after the test
Data storage on a removable Compact Flash (CF) card, which can be read by any standard memory card reader
Remote interface to integrate CT Analyzer into an automatic production process
Customizable reporting within Microsoft ExcelTM
Easy importing and editing into MS OfficeTM standard software
