New functions for the grid and system protection NA003

TELE adapts the new version of the NA003 according to new and important standards and creates an easier operation

At a glance

The new version 01.04.01f of the grid and system protection device NA003 comes with an essentially revised software update. On the one hand, the device has been adapted to the requirements of the standards G59 / 3/3 LV and G59 / 3/3 MV. On the other hand, a revised setup for an easier programming of the device. In addition, extended operating options are now available for the NA003. Tele’s grid and system protection device can thus be adapted even more easily to internationally valid standards.

New Standards G59/3/3 LV and G59/3/3 MV

  • Adaptation to the new version of the G59 valid since Feb. 1st 2018 (Amendment 3).
  • PShift deactivated, RoCoF activated, threshold RoCoF 1.000 Hz/s, delay 500ms.
  • All delays (except for RoCoF) can be set up to 300s.
  • All errors cause the relay R3 to be energized.
  • Due to the certification conditions, the previous standards (G59 / 3 LV and G59 / 3 MV) have been maintained in the device.

Adaptation of the Open Setup

  • Adaptation of the parameters for RoCof, to fulfil the requirements of G59 (Amendment 3) here as well.
  • All delays can be set up to 300s.
  • All errors cause the relay R3 to be energized.

Extended operating options

  • Installation of a 2nd turbo stage to enable a faster setting of parameter with a big setting range:
    • 1 short key press: change by 1 step
    • If you keep this button pushed, the parameter will change step by step
    • If keep this button pushed longer, the parameter changes faster
    • If you stay even longer on this button, the parameter changes even faster
  •  Self-test can now be triggered either via the menu or from any window in level 1 directly via “ESC”
