Omicron's CT
Analyzer is a unique lightweight instrument designed to meet the
highest standards by performing excitation ratio, polarity and
winding resistance tests on current transformers (CT's) 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, as well as CT switchgear manufacturers and engineers.

Features and Benefits
- Extremely small and lightweight approx. 8kg (17 lb).
- Reduced commissioning time due to fully automatic testing.
- Allows testing and result assessment according to
IEC 60044-1, IEC 60044-6 or IEEE C57.13-1993
(ANSI Standard).
- Accuracy level 0.02%/1min. enables field calibration and
verification of class 0.1 CTs for metering.
- Testing and automated assessment of specialized CT's such as
TPS, TPX, TPY and TPZ.
- Allows testing of CT's for power frequencies from 16.7Hz to
400Hz.
- Automatic analysis of CT's 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.

- Determination of accuracy limiting factor (ALF), instrument
security factor (FS), secondary time constant (Ts), remanence
factor (Kr), transient dimensioning factor (Ktd), knee point
voltage/current, class, saturated and non-saturated inductance.
- Assessment according to defined standards: IEC 60044-1, IEC
60044-6, IEEE C57.13-1993.
