The CT-T1 is a powerful current transformer test instrument specially designed for professional current transformer diagnosing. The main functions are precise turns ratio measurement, excitation curve drawing and knee points detection (ASA 10/50, IEEE 30°, IEEE 45°).

The CT-T1 includes 5 low side cables which can be used to connect to the secondary outputs of a CT. This enables the instrument to perform all various measurements for all taps combinations in the least possible time and in a fully automatic easiest way without having to switch the leads during testing.

In addition to precision, the CT-T1 provides useful tools such as the plotting tool on the colour touch display which be helpful for better diagnosing. The results can be stored in internal or external memory, can be transferred to the Raytech t-base pro software or simply can be printed by using the large 3-inch built-in thermal printer.
