T 2000 Primary current injection test set

T 2000 is a unique solution for all testing operations during commissioning and maintenance of substations, as it allows to perform the test of over-current relays, current and voltage transformers. In addition, T 2000 incorporates a powerful multimeter and phase angle meter, and oscilloscope functions.

Manufactory: ISA - ALTANOVA GROUP (Italy).

Description

T 2000 includes a multiple generator, with six outputs:
  • High AC current;
  • Low AC current;
  • Low DC current;
  • Current impulses;
  • High AC voltage;
  • Low AC voltage.
The selected output is adjustable and metered on the large, graphic LCD display. With the multipurpose control knob and the graphic LCD display it is possible to enter the MENU mode, that allows to control all functions, and makes T 2000 the most powerful testing device, with manual and automatic testing capabilities, and with the possibility to transfer test results to a PC via the RS232 interface. These results can be recorded, displayed and analysed by the powerful TDMS software, which operates with all WINDOWS versions, starting from WINDOWS 98 included.

Features
  • Multi function system for testing: current, voltage and power transformers
  • Current transformer excitation, ratio and polarity test set
  • Primary injection testing capabilities
  • 3000 V AC high-pot test
