System ITTS Series 3.0 is a whole assembly for laboratory or field testing
transformers. The equipments are very compact and can be
accommodated inside a van for
The system includes the following equipments:
Instrument Transformers Test Set Model CTI-CT3
Model CTI Current Comparator lets calibrate
current transformers with secondary nominal current
of 1 A or 5 A using a standard current transformer with only 5 A of nominal
Model CT3 Voltage Comparator lets calibrate voltage transformers with
voltage ratio being different
than that of the standard voltage transformer.
The PC based software guides the operator step by step, calculates ratio
and phase errors, and
results can be pasted into Excel or similar format.
Both comparators CTI and CT3 can also be operated manually, by means of a
with cursors for voltage readings.
2. Standard Current Transformer Model TI 1205
Includes most primary currents from 5 A up to 1 200 A (21 ratios)
Secondary nominal current: 5 A
Accuracy is 50 ppm
