Current transformer testers manufactured by NDB Technologies, Inc. are rugged and user-friendly instruments used for the commissioning and maintenance of power systems. The testers are available in two models: CTTx2 and CTTx5. The former has two tap connectors, while the latter has five. For efficient data transfer and analysis, a PC software is also included with the device. The PC interface is composed of an RS-232C & USB port.
Data can be stored both in an internal memory and in a flash drive. 20ft(6m) “X” & 35ft(10m) “H” cables also come with the instrument. The testers are enclosed in a waterproof housing/case with wheels and a retractable handle. They are designed for application in CT saturation/excitation, CT ratio, polarity & phase angle, CT winding resistance, CT insulation resistance, and CT burden.
