CTTx2 and CTTx5

Current Transformer Testers
The CTTx2 & CTTx5 are rugged and easy to use current transformer testers, that offer automatic & manual testing
modes. These instruments are designed to deliver fast and reliable measurements.

COMPETITIVE ADVANTAGES
t High resolution color display
t All tests are performed in automatic sequence t
t without the need for operator intervention
t Rugged design to meet the most demanding t
t field testing environments
t Large internal memory
t Full QWERTY keypad for easy data entry

OPERATION
The CTT will test the Current Transformer Ratio, Phase
shift, Polarity, Excitation, Saturation, Winding resistance
and Insulation resistance using the voltage method in
compliance with ANSI/IEEE C57.13.1 & IEC 600441 standards, where voltage is applied to the secondary
X terminals of the current transformer. The CTT burden
test injects a current into the secondary loop to verify
the integrity of the current circuit and to determine its
impedance & VA. This information is required to insure
the CT will perform under all circumstances. The CTT
can also test the ratio, polarity, phase shift, winding
resistance & insulation resistance of voltage transformers.
