T 3000 Primary current injection test set

T 3000 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. It is also capable of testing energy meters and transducers. In addition, T 3000 incorporates a powerful multimeter and phase angle meter, and oscilloscope functions.

Manufactory: ISA - ALTANOVA GROUP (Italy).

Description

T 3000 contains three independent generators:
  • Main generator. It has six outputs: High AC current; Low AC current; Low DC current; Current impulses; High AC voltage; Low AC voltage
  • Auxiliary AC voltage generator: it generates an independent, phase adjustable AC voltage
  • Auxiliary DC voltage generator, to feed the relay under test.
All outputs are adjustable and metered on the large, graphic LCD display. With the multi-purpose control knob and the graphic LCD display it is possible to enter the MENU mode,
that allows to control all functions, and makes T 3000 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 substation equipment such as: current, voltage and power transformers, over-current protection relays, energy meters and transducers
  • Primary injection testing capabilities
  • 3000 V AC high-pot test
