T-2000 Current and voltage transformer testing device - I.S.A. - Altanova group

Multifunctional system for testing current transformers (CT), voltage transformers (VT), power transformers, overcurrent protection, electricity meters, converters and grounding networks. The T-2000 allows for semi-automatic testing, which significantly reduces test time and prevents errors.

The T-2000 device is designed for testing current transformers (CT), voltage transformers (VT), power transformers, overcurrent protection, electricity meters, converters and grounding networks.

The T-2000 test system includes one main generator with 6 outputs: high-current AC (up to 800 A), low-current AC (up to 60 A), low-current DC (up to 6 A), pulse current (up to 10 A) , high-voltage alternating voltage (up to 3000 V), low-voltage alternating voltage (250 V). All outputs are adjustable and have their own meters.

Parameter checks are carried out in semi-automatic mode. The operator selects the type of test, the outputs used and controls the output values. The device, in turn, measures output and input quantities and calculates indirect parameters, such as transformation ratio, resistance, inflection point when taking the current-voltage characteristic

The current status of the output values is displayed on the large graphic LCD display. Using the multifunction control button and the graphic LCD display, you can enter the MENU mode, with which you can control all functions of the device.

Test results can be recorded, viewed and analyzed using TDMS software. The TDMS program is available entirely in Russian, it allows you to control the T-2000 setup, download test results, prepare professional test reports and export them to various formats using a graphical user interface.

In addition to the T-2000 device, various options can be supplied that expand the functionality of the device.
