SFT 2841 expert UMI

The UMI on the front panel of Sepam may be completed by an expert UMI comprising the SFT2841 PC software tool, which may be used for all Sepam functions

– parameter setting, – local operation – and customization.

The expert UMI comes as a kit, the SFT 2841 kit, which includes:– Sepam software CD– CCA 783 cord

5. Timer hold

Definitions:– Timer hold: time added to reset time to:

– delay the return to the initial situation – and activate a memory for the detection of recurrent faults.

– Reset time (of a protection function): time of return to the initial situation of a protection function after the disappearance of the fault (<50ms)

Applications:– definite time: detection of recurrent faults on networks earthed by a

Petersen coil (for directional earth fault protection)– IDMT: used to have a reset time similar that of a disc-type

electromechanical relay for improved discrimination when the relay is situated upstream.

5. H2 restraint

Stability upon transformer energizing

This function should only be activated with Σ 3I earth fault protection upstream from a transformer

Transformer energizing generates number 2 harmonics . This function restrains the protection if the harmonic is above the set 17% threshold.

MAIN POINTS TO REMEMBER


faire "ce qu'il faut retenir"

A compléter

Astuces de paramétrage

Faire attention que le type de fichier corresponde au type de Sepam

Ne pas oublier de mettre les protections en service

Ne pas perdre le code de déverrouillage du SFT2841 qui se trouve sur la boite du CD d’installation.

Penser à valider les sorties qui doivent être utilisées dans la matrice de commande.

Le changement du type arrivée / départ modifie le signe de la puissance.

La passage par la navigation guidée permet de ne pas oublier de configurer des écrans.

Le SFT2841 vérifie la cohérence des valeurs rentrées en fonction des plages de réglage et du ratio des TC / TP
