ABB REF615 ANSI 5.0 FP1

() = optional

1) One of the following can be ordered as an option; Admittance based E/F, Wattmetric based E/F or Harmonics based E/F. The option is an addition to the existing E/F of the

original configuration. The optional E/F has also a predefined configuration in the relay. The optional E/F can be set on or off.

2) Multi-purpose protection is used for, for example, RTD/mA based protection, or Analogue Goose

3) Light only

4) Io selectable by parameter, Io measured as default

5) Io selectable by parameter, Io calculated as default

6) Io calculated is always used

7) IoB calculated is always used

8) IoB calculated and 3IB are always used

9) Uo selectable by parameter, Uo measured as default

10) Uo calculated and negative sequence voltage selectable by parameter, Uo calculated as default

11) Uo calculated is always used

12) Uo measured is always used

13) IoB measured is always used

14) IoB measured and 3IB are always used

15) Io measured is always used

16) IoB selectable by parameter, IoB measured as default

17) Power quality option includes Current total demand distortion, Voltage total harmonic distortion and Voltage variation.

18) Available in IED and SMT but not connected to anything in logic.

19) Must be added with ACT to be available in SMT and in IED.

20) Uob measured is always used for unbalance protection with unearthed single Y connected capacitor bank.

21) The Iunb measurements values will be taken from this block and put in Measurent view.

22) Master Trip included and connected to corresponding HSO in the configuration only when BIO0007 module is used. If additionally the ARC option is selected, then ARCSARC
